[0001a] The present application is a divisional application of Australian Patent Application No. 2014277770, which is a divisional application of Australian Patent Application No. 2010319435 10 (PCT/US2010/056520), the content of each of which is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

[0002] The present invention relates to bioactive fractions isolated from stress-induced .5 photosynthetic organisms, methods of isolating the bioactive fractions, methods of using the bioactive fractions, and compositions and formulations containing the bioactive fractions.

BACKGROUND OF THE INVENTION

[0003] Environmental stresses are major limiting factors of plant development, growth and Ό productivity. There are two general types of stress factors that can produce plant responses: (1) abiotic, which arise from excesses or deficiencies in the environment, and (2) biotic, which are imposed by other organisms.

[0004] Plant responses to stress factors trigger modulation of cellular metabolism, altered gene expression, changes in the growth rate, yield of phytomass, and reproductive capabilities. The 25 following conditions, among others, cause plant stress: water-logging and submergence, drought, high or low temperatures, high or low soil salinity, inadequate minerals in the soil, too much or too little light, exposure to high concentrations of ozone and underexposure or overexposure to UV light.

[0005] Resistance or sensitivity of photosyntlietic organisms to the stress depends on the species, genotype and development age. There are three major stress resistance mechanisms: (1) avoidance 30 mechanisms which prevent exposure to the stress; (2) tolerance mechanisms which permit the plant to withstand stress; and (3) acclimation, i.e., alteration of plant physiology in response to stress.

[0006] Stress response is initiated when plants recognize stress at the cellular level and then stress recognition activates signal transduction pathways that transmit information within the individual cell and throughout the plant. Regulators of plant stress response include, but are not limited to, abscisic 35 and jasmonic acids, osmotic adjustment factors, 1 #13450535 osmotin, protein stabilizing factors, heat shock proteins, specific mRNAs, Ca2+ ions and defense-related secondary metabolites. 2017213518 10 Aug 2017 [0007] The impressive ability of plants to sustain high levels of multiple stresses indicates that the defense mechanism is very complex in nature and involves multiple 5 mechanisms of cellular adaptation and numerous metabolic pathways. Although this comprehensive and powerful defense system is not completely understood yet, utilization of its components and their interactions can be very beneficial.

[0008] U.S. Patent Application Publication No. 2009/0031446 discloses stress-related polypeptides and methods of use in plants: a transgenic plant transformed with an SLSRP 0 coding nucleic acid, wherein expression of the nucleic acid sequence in the plant results in increased growth under water-limited conditions and/or increased tolerance to an environmental stress as compared to a wild type variety of the plant.

[0009] ft was shown that synthesis of rutin, an antioxidative flavonoid in buckwheat herbs, is affected by different UV-B radiation levels: the rutin content is lower in plants 5 growing at a level of UV-B light corresponding to 17% ozone depletion. Applied doses of UV-B radiation exert a state of stress, where limits of tolerance are exceeded and adaptive capacity is overtaxed, possibly resulting in a disturbance in rutin synthesis. The measurements suggest that ambient levels of UV-B radiation stimulate rutin accumulation in buckwheat plant compared with reduced UV-B level. The effect is more evident in leaves Ό than in flowers. Enhanced UV-B radiation obstructs rutin accumulation (Samo Kreft et al., Journal of Experimental Botany, Vol. 53, No. 375, pp. 1801-1804, August 2002).

[0010] Broad physico-chemical diversity of stress-induced complexes and compounds and absence of universal specific “markers” suggest that capturing all stress-induced biologically active complexes and compounds in a single extract is not possible. 25 [0011] Therefore, there is a need for methods and systems for generating and isolating stress-induced bioactive fractions in photosynthetic plants. The present invention is directed to overcoming these and other deficiencies in the art. 30 2

SUMMARY OF THE INVENTION 2017213518 10 Aug 2017 [0012] The present invention is generally directed to biologically active fractions obtained from stress-induced photosynthetic organisms (the biologically active fractions being referred to herein as “BAFSI”). The BAFSI of the present invention have complexes 5 and compounds with desirable target activities that are generated by natural defense mechanisms. The BAFSI can be captured and isolated via fresh plant fractionation technologies and are well suited for their utilization in skin care, sun care, hair care and personal care formulations and applications comprising at least one BAFSI and other cosmetically acceptable ingredients and actives. 0 [0013] In one aspect, the present invention relates to a method for producing a stress- induced photosynthetic organism for use in isolating altered bioactive fractions (i.e., BAFSI). This method involves (i) providing a photosynthetic organism and (ii) cultivating the photo synthetic organism under stress-inducing cultivation conditions effective to produce a stress-induced photosynthetic organism suitable for use in isolating an altered bioactive 5 fraction therefrom. Suitable stress-inducing cultivation conditions include, without limitation, subjecting the photosynthetic organism to a stress factor or to a plurality of stress factors. The stress factor or plurality of stress factors can include, without limitation, stress factors such as ultraviolet light, ozone, osmotic pressure, hydrostatic pressure, and/or a combination thereof. The stress factor or plurality of stress factors used in this method are Ό effective to alter at least one characteristic of at least one bioactive fraction isolated from the stress-induced photo synthetic organism compared to a corresponding bioactive fraction isolated from a non-stress-induced photo synthetic organism. The present invention also relates to a stress-induced photo synthetic organism produced by this method.

[0014] In another aspect, the present invention relates to a method for isolating an 25 altered bio active fraction from a stress-induced photo synthetic organism. This method involves (i) providing a stress-induced photosynthetic organism produced according to the present invention; (ii) separating the stress-induced photo synthetic organism into cell juice and a cell walls component; (iii) treating the cell juice under conditions effective to yield a bioactive fraction, where the bioactive fraction includes, but is not limited to, a cell serum 30 fraction, a membrane fraction, a cell juice supernatant fraction, and a cell serum filtrate fraction; and (iv) isolating the bioactive fraction from the treated cell juice. The isolated bioactive fraction has at least one altered characteristic compared to a corresponding 3 bioactive fraction isolated from a non-stress-induced photo synthetic organism. The present invention also relates to an altered bioactive fraction isolated according to this method. 2017213518 10 Aug 2017 [0015] In another aspect, the present invention relates to a bioactive composition that includes an isolated bioactive fraction derived from a stress-induced photosynthetic 5 organism, where the bioactive fraction includes, but is not limited to, a cell serum fraction, a membrane fraction, a cell juice supernatant fraction, and a cell serum filtrate fraction.

[0016] In another aspect, the present invention relates to a bioactive topical formulation suitable for topical application to a mammal, where the bioactive topical formulation includes (i) a topically effective amount of the bioactive composition of the 0 present invention and (ii) a topically acceptable carrier.

[0017] In another aspect, the present invention relates to a method for inhibiting inflammatory activity in skin tissue of a mammal. This method involves (i) providing the bioactive composition according to the present invention and (ii) applying the bioactive composition to the skin tissue in an amount effective to inhibit inflammatory activity in the 5 skin tissue.

[0018] In another aspect, the present invention relates to a method of protecting skin tissue of a mammal from ultraviolet light-induced damage. This method involves (i) providing the bioactive composition according to the present invention and (ii) applying the bioactive composition to the skin tissue in an amount effective to reduce ultraviolet light- Ό induced damage of the skin tissue and to prevent oxidative damage of the skin tissue.

[0019] In another aspect, the present invention relates to a method for normalizing skin disorders in skin tissue of a mammal. This method involves (i) providing the bio active composition according to the present invention and (ii) applying the bioactive composition to the skin tissue in an amount effective to normalize a cell disorder in the skin tissue. 25 [0020] In another aspect, the present invention relates to a system for cultivating stress-induced photo synthetic organisms. This system includes (i) a bioreactor for cultivating a photo synthetic organism; and (ii) a cultivation control system for controlling cultivation conditions in the bioreactor. The cultivation control system is configured to introduce a stress factor or a combination of two or more stress factors into the bioreactor, and is 30 configured to modulate the intensity, duration, and/or concentration of the stress factor or combination of two or more stress factors in the bioreactor. The stress factor or combination of two or more stress factors include, but are not limited to, a stress factor such as ultraviolet light, ozone, osmotic pressure, hydrostatic pressure, and a combination thereof. 4 [0021] Stress induced biologically active complexes and compounds (“SIBAC”) isolated via fresh plant fractionation technologies can also accurately be described as biologically active fractions from stress-induced photosynthetic organisms (abbreviated herein as “BAFSI”). As used herein, the terms “biologically active” and “bioactive” are used 2017213518 10 Aug 2017 5 interchangeably.

[0022] BAFSI contain complexes and compounds that are generated by natural defense mechanisms, which protect photosynthetic organisms (plants, marine organisms) against various stresses and provide subsequent access to all these complexes and compounds and a basis for their evaluation. 0 [0023] It was surprisingly and unexpectedly found that various stress factors, their intensity, and their duration generate modulatory effects (increase, decrease or alteration) on the various characteristics of the BAFSI, including, but not limited to: physico-chemical properties (dry matter content; osmolality, surface tension, surface modification capabilities) and biological activities that include, but are not limited to: enzyme inhibition; antioxidant 5 activity and free radical scavenging.

[0024] It was also unexpectedly found that similar stress factors applied to different photo synthetic organisms can produce different effects on the characteristics of BAFSI obtained from these plants.

[0025] Various stresses applied to the cultivated photo synthetic organisms induce Ό generation of BAFSI with desirable biological activities and physico-chemical properties, which also can be useful in skin care, sun care, hair care and personal care compositions and applications. For example, BAFSI of the present invention can be used as ingredients regulating activity of certain enzymes (trypsin, elastase, etc.), which play important roles in human skin metabolism, as well as ingredients with antioxidant and free radical scavenging 25 activities. The isolation and screening of prospective BAFSI with the optimal combination of the useful physico-chemical properties and biological activities that include, but are not limited to, antioxidant and free radical scavenging activities; inhibition of enzymes associated with skin ageing and environmental damage, skin protection and repair of human tissues, can create a foundation for developing novel multifunctional ingredients for use in the skin care, 30 sun care, hair care and personal care markets.

Basic input stress signals include, but are not limited to, impulse function (f(t) = Sit)), unit step function (f(t) = u(t)), and ramp function (f(t) = i). 0 [0028] Photo synthetic organisms of the present invention include, but are not limited to, aquatic photosynthetic organisms that are valuable sources of ingredients with various biological activities.

This system includes (i) a bioreactor for cultivating a photosynthetic organism; and (ii) a cultivation control system for controlling cultivation conditions in the bioreactor. The cultivation control system is configured to introduce a 5 stress factor or a combination of two or more stress factors into the bioreactor, and is configured to modulate the intensity, duration, and/or concentration of the stress factor or combination of two or more stress factors in the bioreactor. The stress factor or combination of two or more stress factors include, but are not limited to, a stress factor such as ultraviolet light, ozone, osmotic pressure, hydrostatic pressure, and a combination thereof. 0 [0090] In one embodiment, the system of the present invention is used for cultivating an aquatic photosynthetic organism, where the bioreactor is configured for cultivating the aquatic photosynthetic organism in a liquid medium. An example of a suitable configuration of the system for use with aquatic photosynthetic organisms is illustrated in FIG. 17. In a particular embodiment, the bioreactor can be, without limitation, an aquarium. Various 5 components of one embodiment of the system of the present invention are set forth in

Table 1 (herein below). In view of the teachings herein, one of ordinary skill in the art can readily determine other general or specific components suitable for use in the system of the present invention, and such other general or specific components are therefore contemplated by the present invention. :o [0091] Set forth herein below are additional details regarding the various aspects and embodiments of the present invention.

[0092] In one embodiment, giant brown kelp (Macrocystis pyrifera) was selected due to its fast growth rate and ability to survive at extreme conditions, particularly at high pressure and relatively low temperature. It is found off the coasts of several continents 25 around the world, for example, off the west coast of North America, from southern Alaska to Baja California; off the coast of South America, South Africa, and southern Australia. In order for giant kelp to flourish in a particular environment, it must have a hard surface for attachment, high nutrient concentration, moderate water motion, and clear and clean ocean water. Macrocystis prefers salty, well-mixed salty water in the outer coastal waters (Connor J, 30 Baxter C, Kelp Forest. Monterey Bay Aquarium Foundation, Monterey: 1989). Giant brown kelp is a rich source of iodine, calcium, and sulfur, and a good source of iron, phosphorus, sodium, potassium, magnesium, and the vitamins A, D, E, K, and B complex. The main constituents of kelp are: mucopolysaccharides, alginates, phenolic compounds, 15 polar lipids, and glycosyl ester diglycerides, as well as protein, carbohydrates, essential fatty acids, amino acids, and about thirty minerals, chlorophyll a and c, as well as carotenes and xanthophylls (Wurges, J., and R. J. Frey. 2005. In J. L. Longe, The Gale Encyclopedia of Alternative Medicine, Farmington Hills, Mich: Thomson/Gale. ISBN 0787693960). Cell 5 walls are composed of cellulose layered with polysaccharide (such as the valuable alginic acid). 2017213518 10 Aug 2017 [0093] Giant kelp stipes are similar to stems of terrestrial plants. The essential sugars produced in photosynthesis are used to fuel their own metabolic needs, as well as transport them to other parts of the algae, including the holdfast, spore producing blades, and new 0 fronds.

[0094] Giant brown kelp blades are the site where most of the sun’s light energy is captured and converted into sugars by photosynthesis; sugars produced are then used by the algae for energy. Giant brown kelp pneumatocysts are gas-filled bladders that act as buoys to raise the blades closer to the surface where photosynthesis can occur (Bold HC, Wynne M J. 5 Introduction to the Algae. Prentice Hall, Englewood Cliffs: 1978).

[0095] A giant kelp holdfast in appearance looks similar to roots. However, these roots do not uptake nutrients and water as terrestial plants do. The holdfast maintains the kelp’s position. The holdfast of giant kelp is perennial, and will last one to seven years (Connor J, Baxter C, Kelp Forest. Monterey Bay Aquarium Foundation, Monterey: 1989). :0 [0096] In another embodiment, green algae (Chaetomorpha linurn) were selected due to its fast growth rate, its ability to survive at relatively high temperature and its high level of photo synthetic activity relative to Macrocystis pyrifera. Chaetomorpha linum is found in relatively shallow sub tropical to tropical Pacific Ocean reefs. It is a free floating algae that grows in filamentous clumps without attachment to any substrate. Chaetomorpha linum is 25 frequently aqua cultured for use as a natural filter to remove impurities, especially nitrates.

[0097] In another embodiment, generation of BAFSI was initiated by different stress factors which include, but are not limited to, ultraviolet light (UV), ozone (O3), osmotic pressure (Biological Control Systems Analysis. John H. Milsum - McGraw-Hill Book Company NY, 1966), and the significant change in original cultivation conditions, for 30 example, in hydrostatic pressure.

[0098] In one embodiment, basic input stress signals presented in FIG. 1 include, but are not limited to, impulse function (f(t) = S(t)), unit step function (f(t) = u(t)), and ramp function (f(t) = t). The functions describing stresses applied to algae are shown in FIG. 2. 16 [0099] In another embodiment, in case of Giant Kelp, there is an additional factor of hydrostatic stress, as cultivation in aquariums provides less water pressure than common for natural growth conditions for the species. Hydrostatic stress begins when the kelp is removed from its normal environment and ends with the end of the experiment. It is a factor that 2017213518 10 Aug 2017 5 applies to all of the kelp in the experiment equally and is thus not shown.

Cultivation Conditions and Parameters [0100] In one embodiment of the present invention, four identical 150 liter aquariums 0 were allowed to cycle for 14 days with 35 g/1 artificial sea salt. Then Proline F/2 algae food was added to each aquarium and maintained by monitoring the nitrate level during the course of cultivation. Detailed information related to the equipment components of this embodiment is presented in Table 1. 5 Table 1

The UV source modeled radiation in the UVB region. Wave makers provided water flow and turbulence to simulate natural 5 environmental conditions. A control system monitored pH, redox potential, conductivity, ozone concentration and temperature. Additionally, timers controlled lighting, UV and ozone systems. Osmolality, refractive index, and specific gravity along with levels of ammonia, nitrite, nitrate, phosphate, calcium and carbonate hardness (KH) were also monitored. One aquarium was always used as control and three others were used to introduce (a) three 0 different levels of selected stress factor or (b) three different types of stress factors.

[0102] Set forth in FIG. 17 is a photo of these aquariums with cultivated Giant brown kelp (Macrocystis pyrifera).

[0103] In one embodiment, UVB stress in aquariums was applied with external UVB lights. Two 30 Watt UVB light fixtures were installed over the aquariums and intensity of 15 UVB was measured with a UVX Radiometer. Ozone stress in aquariums was introduced by injection of ozone into the aquariums with the system described in Table 1. Aquariums without ozone generation also had the same ozone injection system installed to eliminate differences in air and water flow. Dissolved Ozone concentration was measured with Aquasensors Ozone Sensor and Analyzer. Osmotic stress in aquariums was introduced via 20 regulation of salt water concentration. The osmolality was measured with Model 3250 freezing point depression Osmometer (Advanced Instruments, Inc., MA). Hydrostatic stress (reduced hydrostatic pressure conditions) in aquariums was in effect for Giant brown kelp, which typically grow in deeper water (10 ft or deeper). The ranges of cultivation parameters used for control and stressed systems stress factors and their parameters are presented in 25 Table 2. 18 2017213518 10 Aug 2017

For daylight cycle, typically 12 hours/day. For UVB lighting from 3 hrs/day to 12 hours/day. ***) Hydrostatic stress occurs when algae, which typically grow in deeper water (10 ft or deeper), for example, 0 Giant brown kelp (Macrocystis pyrifera), are transferred and then cultivated in more shallow reservoirs (aquariums) with reduced hydrostatic pressure compared to that in original conditions.

[0104] In one embodiment, the ranges of cultivation parameters used for control and stressed systems with Giant brown kelp (Macrocystis pyrifera) were as follows: Cultivation 15 times were 72 hrs (3 days) or 96 hrs (4 days). Control (No stress): Giant brown kelp (Macrocystis pyrifera) was harvested from original cultivation conditions in deeper water and processed without being transferred to an aquarium; Hydrostatic pressure stress only was ongoing during respective cultivation times; Hydrostatic stress occurs when algae, which typically grow in deeper water (10 ft or deeper), for example, Giant brown kelp (Macrocystis 20 pyrifera), are transferred and then cultivated in more shallow reservoirs (aquariums) with reduced hydrostatic pressure compare to the one existing in original cultivation conditions; Hydrostatic Stress + UVB Stress = 2 mW/cm2 UVB 3-12 hrs/day; Hydrostatic Stress +

Ozone Stress = lOOmg/hr continuous injection; Hydrostatic Stress + Osmotic Stress - 19 osmolality of cultivation media = 75% of control. Cultivation times were: 72 hrs (3 days) or 96 hrs (4 days). 2017213518 10 Aug 2017 [0105] In one embodiment, the ranges of cultivation parameters used for control and stressed systems with Green algae (Chaetomorpha linum) that typically grow in shallow 5 water and thus do not experience hydrostatic stress in the experiment were as follows:

Cultivation times were 24 hrs (1 day), 96 hrs (4 days), 288 hrs (12 days), 456 hrs (19 days). Control (No stress). UVB Stress = 2 mW/cm2 UVB 12hrs/day; Ozone Stress = lOOmg/hr continuous injection. Osmotic Stress - osmolality of cultivation media = 85% of control. 0 Definitions and Methods [0106] Set forth below are various definitions of characteristics that can be determined for the bioactive fractions of the present invention, and related methods for measuring or analyzing these characteristics. 5 Surface tension [0107] Surface tension is defined as the force along a line of unit length, where the force is parallel to the surface but perpendicular to the line. Surface tension is measured in forces per unit length, its SI unit is N/m (Newtons per metre) (Pierre-Gilles de Gennes; Fran9oise Brochard-Wyart; David Quere (2002). Capillary and Wetting Phenomena — Ό Drops, Bubbles, Pearls, Waves. Springer. ISBN 0-387-00592-7; White, Harvey E. (1948). Modem College Physics, van Nostrand. ISBN 0442294018).

[0108] Surface tension is caused by the attraction between the liquid's molecules by various intermolecular forces. In the bulk of the liquid, each molecule is pulled equally in every direction by neighboring liquid molecules, resulting in a net force of zero. At the 25 surface of the liquid, the molecules are pulled inwards by other molecules deeper inside the liquid and are not attracted as intensely by the molecules in the neighboring medium (be it vacuum, air or another liquid). Therefore, all of the molecules at the surface are subject to an inward force of molecular attraction which is balanced only by the liquid's resistance to compression, meaning there is no net inward force. However, there is a driving force to 30 diminish the surface area. Thus, the liquid squeezes itself together until it has the locally lowest surface area possible. As a result of surface area minimization, a surface will assume the smoothest shape it can. Since any curvature in the surface shape results in greater area, a higher energy will also result. Consequently, the surface will push back against any curvature 20 in much the same way as a ball pushed uphill will push back to minimize its gravitational potential energy. 2017213518 10 Aug 2017 [0109] Surface tension measurements were performed using a Kruss EasyDrop drop shape analysis system with attached computer running Kruss DSA1 software for device 5 control, image acquisition and analysis of drop shape images. Disposable 2mL syringes with 1.8mm diameter disposable dosing needles were used to hold and dispense the samples, with new syringe and new needle for every different sample material. The procedure for performing the measurement is described in Kruss Software for Drop Shape Analysis DSA1 v 1.91 User Manual as supplied with the system. Room lighting was adjusted to eliminate 0 bright and non-diffuse light, thus preventing reflections on drop surface. System was turned on, backlight set to 25% intensity, syringe and needle positioned for needle image to take up -10% of the frame. Focus was adjusted so sharpness as determined by software was maximum achievable. Region of interest was defined with a hanging drop of deionized water. Drop type was set to hanging drop. Image magnitude was read as per needle diameter. 5 Immersion medium density was entered as air density at room temperature at sea level. Water was used for initial control measurement. For water, and for each sample material, sample density was entered, and then volume necessary to produce a properly shaped pendant drop was determined. Following that, surface tension was measured on three pendant drops, a fresh drop for every measurement. Young-Faplace drop contour fit was used for calculation. Ό The mean of the three measurements was considered as the surface tension of a given sample material.

Osmolality [0110] Osmolality is the measure of solute concentration, defined as the number of 25 osmoles of solute per kg of solution. Osmolality measures the number of osmoles of solute

particles per unit mass of solution. Osmolality is distinct from molarity because it measures moles of solute particles rather than moles of solute. The distinction arises because some compounds can dissociate in solution, whereas others cannot. Ionic compounds, such as salts, can dissociate in solution into their constituent ions, so there is not a one-to-one relationship 30 between the molality and the osmolality of a solution. For example, sodium chloride (NaCl) dissociates into Na+ and Cl“ ions. Thus, for every 1 mole of NaCl in solution, there are 2 osmoles of solute particles (i.e., a 1 M NaCl solution is a 2 Osm NaCl solution). Both sodium and chloride ions affect the osmotic pressure of the solution. Nonionic compounds do not dissociate, and form only 1 osmole of solute per 1 mole of solute. For example, a 1 M 21 solution of glucose is 1 Osm (Widmaier, Eric P.; Hershel Raff, Kevin T. Strang (2008). Vander's Human Physiology, 11th Ed. McGraw-Hill. pp. 108-112). Osmometer, model 3250 (Advanced Instruments, Inc) was used to determine osmolalities of BAFSI. This instrument utilizes freezing point depression as measuring principle. Freezing point is a colligative 5 property that is dependent on the presence of dissolved particles and their number, but not their identity. The freezing point depression happens both when the solute is an electrolyte, such as various salts, and a non-electrolyte, such as carbohydrates. 2017213518 10 Aug 2017

Dry matter 0 [0111] Dry matter reflects the concentration of non volatile components in BAFSI.

Dry matter levels were determined by comparing the weight of liquid sample with weight of residual dry matter after liquid components have been evaporated. Disposable aluminum weighing dishes (VWR 25433-016), Ohaus Explorer E00640 balance (Ohaus Corporation) and Shel Lab model 1400E oven (VWR) set at 105 C were utilized. Dry matter percentage is 5 calculated as (‘tare+dry’-‘tare’) / (‘tare+wet’-‘tare’) * 100.

Vitro Skin (N-19) Surface Modification after Application of BAFSI

[0112] A test methodology that utilizes measurements of the contact angle of water to quantify the effects of various substances on the surface properties of a skin-substitute Ό substrate (Correlating Water Contact Angles and Moisturization/Sensory Claims” by Olga V. Dueva-Koganov et al. Cosmetics & Toiletries, January 2007, Vol. 122, No. 1, pp. 20-27) was employed. The data presented in this article show that contact angle measurements can be used to quantify and compare the effects of skin care products on the surface properties of this skin-like substrate. Products that generate lower contact angles (less than 80 deg.) tend to 25 make more sensory claims related to light and non-greasy feel, and short-term moisturization, while products that produce relatively high contact angles tend to make more claims related to long-term moisturization.

[0113] Contact angles were measured according to sessile drop method using Kruss EasyDrop drop shape analysis system with attached computer running Kruss DSA1 software 30 for device control, image acquisition and analysis of drop shape images (www.kruss.de/en/products/contact-angle/easydrop .html).

[0114] Deionized water was used as a probe solution and Vitro Skin (N-19) from IMS, Inc. as a substrate. Application dose of test BAFSI was 2 mg/sq. cm that is similar to the topical application dose of products used in various skin studies in vivo. 22

Elastase inhibition 2017213518 10 Aug 2017 [0115] Elastase is an enzyme that is capable of degrading a number of proteins including elastin, an elastic substance in the skin that supports its structural framework. 5 Elastase is involved in skin inflammation, ageing, photoageing, wrinkle formation, etc. Elastase inhibitory activity was determined by a kinetic colorimetric assay adapted for use with 96-well micro titer plates (Coming 3641) from Coming Incorporated (Coming, NY) and Synergy 2 microplate reader from BioTek Instmments, Inc. (Winooski, VT). Enzymatic activity in cleaving the substrate was indicated by a development of yellow color measured as 0 increase in absorbance at 410 nm wavelength. The mean of maximum rates of absorbance increase for negative control wells was considered as 100% of enzyme activity, and IC50 was calculated as concentration of sample in the well necessary to reduce the enzyme activity to 50%. Lower IC50 values indicate higher elastase inhibition activity. The N-Methoxysuccinyl-Ala-Ala-Pro-Val-pNA substrate (EPC FH237), and elastase (EPC SE563) were obtained 5 from EPC (Elastin Products Company, Inc., Owensville, MO). Reaction volume in each well was 200 μΐ, with concentration of elastase equal to 0.87 units/ml, and substrate equal to 363 μΜ. This procedure was adapted from method titled “Assay with N-MeO-Suc-Ala-Ala-Pro-Val-pNA (EPC No. FH237) as substrate” from page 84 of Elastin Products Company, Inc. Research Biochemicals Catalogue (2004, 92 pages). :0

Trypsin inhibition [0116] Trypsin is a proteolytic enzyme that is involved in in vivo epidermal proliferation and inflammation. Trypsin inhibition activity was determined by a kinetic colorimetric assay designed for use with 96-well microtiter plates (microplates) and 25 computer-controlled microplate reader. Enzymatic activity in cleaving the substrate was indicated by a development of yellow color measured as increase in absorbance at 405 nm wavelength. The mean of maximum rates of absorbance increase for negative control wells was considered as 100% of enzyme activity, and IC50 was calculated as concentration of sample in the well necessary to reduce the enzyme activity to 50%. Lower IC50 values 30 indicate higher trypsin inhibition activity. L-BAPA (Να-Benzoyl-L-arginine 4-nitroanilide hydrochloride) substrate, trypsin, and solvent reagents were obtained from Sigma-Aldrich. pH 8.2 Tris-CaCb buffer was used for preparing working solutions of trypsin and L-BAPA substrate. Deionized water was used as solvent for buffer reagents, as negative control, and as 23 the diluents for preparing serial dilutions of the samples. Reaction volume in each well was 200 μΐ, with concentration of trypsin equal to 60 nM and substrate equal to 0.5 mM. 2017213518 10 Aug 2017

Antioxidant activity 5 [0117] Antioxidant is an agent that reduces the damage caused by oxidation.

Antioxidant activity was determined by ORAC testing using an adaptation of the method described in “Performing Oxygen Radical Absorbance Capacity (ORAC) Assays with Synergy HT Multi-Detection Microplate Reader” Application Note from BioTek available at (www.biotek.com/resources/docs/ORAC_Assay_Application_Note.pdi) for use with Synergy 0 2 microplate reader from BioTek Instruments Inc (Winooski, VT). In this assay, AAPH (2, 2'- azobis 2-amino-propane) generates reactive oxygen species which damage the fluorescent probe (sodium fluorescein). Antioxidants such as (R)-Trolox methyl ether prevent or slow this damage, and their effects can be quantified by fluorescence measurements. Fluorescence readings were taken with excitation wavelength set at 485 nm and emission wavelength set at 5 528 nm, with reaction volume of 200 μΐ, AAPH concentration of 55 mM, sodium fluorescein concentration of 1.33 μΜ, and (R)-Trolox methyl ether concentration range between 80 μΜ and 2 μΜ. Sodium fluorescein (Fluka 46960), AAPH (Sigma 440914) and (R)-Trolox methyl ether (Fluka 93509) were obtained from Sigma-Aldrich (St. Louis, MO). AUC (Area Under Curve) values were calculated as sum of proportions (current fluorescence reading for the :0 well divided by first fluorescence reading for the well). Average of AUC values of wells with deionized water was subtracted from AUC of wells with (R)-Trolox methyl ether and wells with test articles to obtain AUC corresponding to preservation of fluorescence by antioxidants. A calibration curve was generated as function of a wells’ antioxidant-related AUC showing (R)-Trolox methyl ether weight-equivalent ORAC activity. ORAC activity for 25 test articles was then calculated as units weight test article necessary to achieve antioxidant effect equal to one produced by 1 unit weight (R)-Trolox methyl ether, with lower numbers indicating higher ORAC activity. DPPH (2,2-Diphenyl-l-Picrylhydrazyl) free radical scavenging activity 30 [0118] Free radical scavenger is an ingredient that reacts with free radicals in a biological system, reduces free radical-induced damage, and protects against the effects of free radicals. Free radical scavenging activity, i.e. DPPH (2,2-Diphenyl-1-Picrylhydrazyl) free radical scavenging activity, was determined by a kinetic colorimetric assay adapted for use with glass-coated polypropylene 96-well microtiter plates (catalog number 400 062) from 24 2017213518 10 Aug 2017 SUN-SRi (Rockwood, TN) and Synergy 2 microplate reader from BioTek Instruments Inc (Winooski, VT). Absorbance was measured at 515 nm wavelength. Reaction volume in each microplate well was 200 μΐ, with initial concentration of DPPH equal to 114 μΜ. L-ascorbic acid was used as positive control. DPPH (Sigma D9132) and USP L-ascorbic acid (Sigma A-5 2218) were obtained from Sigma-Aldrich (St. Louis, MO). Stoichiometry of the reaction was calculated and expressed as units weight test article necessary to quench 1 unit weight DPPH, with lower numbers indicating higher activity. This method was adapted from procedure described in “Use of a free radical method to evaluate antioxidant activity” by W. Brand-Williams et al, published in LWT - Food Science and Technology, Volume 28, Issue 1, 1995, 0 pp 25-30. 5 Ό 25

Color (Gardner Scale) [0119] The Gardner Color scale as specified in ASTM D1544 is a single number colour scale for grading light transmitting samples with color characteristics ranging from light yellow to brownish red. The scale is defined by the chromaticities of glass standards numbered from 1 for the lightest to 18 for the darkest. The Gardner Color of samples was determined on the Lovibond Gardner Comparator 3000 (The Tintometer Limited of Salisbury, UK), a 3-field instrument for visually determining the Gardner Color of samples by direct comparison with colored glass standards. Refractive Index, nD [0120] Refractive Index was determined by measuring on Arias 500 reffactometer from Reichert Analytical Instruments (Depew, NY) with temperature regulation provided by Polystat model 12108-10 temperature controller from Cole-Parmer (Vernon Hills, Illinois). Procedure is based on the instruction manual for Arias 500 reffactometer, sections 6.0, 4.1 and 4.4-4.5. pH Determination [0121] pH is defined as minus the decimal logarithm of the hydrogen ion activity in a 30 solution and used to determine acidity or basicity of a solution. [0122] pH levels were determined on a pH meter Model 250 pH / ISE / conductivity meter from Denver Instrument Company (Bohemia, NY) with pH / ATC electrode number 300729.1 (Denver Instrument Company). Procedure is based on Denver Instrument Company 301127.1 Rev. D manual, pages ii and 9 - 12. 25

Determination of wavelength of maximum absorbance in UV spectrum (ληι:1χ, nm) [0123] λη,8χ, nm was determined on Ultrospec 4300 pro UV / Visible 2017213518 10 Aug 2017 spectrophotometer from Biochrom Ltd (Cambridge, UK), formerly under GE Healthcare, 5 formerly known as Amersham Bio sciences, with water heated cell holder (Amersham part # 80-2106-08). The procedure is based on sections 2 and 4 from Amersham manual number 80-2108-25 entitled SWIFT II Applications Software UV/Visible Spectrophotometers, and on pages 7 and 15 from Amersham manual number 80-2111-79 entitled Ultrospec 4300 pro UV/Visible Spectrophotometer User Manual. Instrument control was provided by SWIFT II 0 software suite (Biochrom Ftd) and temperature regulation by CB20 Mini Circulator from Torrey Pines Scientific (Carlsbad, CA).

Depending on the specific photosynthetic organism (plants, aquatic plants or algae) the regimes of this process can be further modified. Photosynthetic organisms are subjected to various stresses, harvested, collected, and washed to yield fresh biomass (plant or algae).

[0128] This fresh biomass is subjected to grinding, maceration, and pressing. Biomass 35 is grinded at 3,000 rpm for 30 seconds. Grinded biomass is immediately pressed using a 26 horizontal, continuous screw press (Compact Press "CP-6", Vincent Corporation, FL). The pressure on the cone is maintained at level 24 kg/cm2, screw speed at 12 rpm, and the temperature increase is < 5°C. As a result, cell juice is effectively separated from cell wall fraction. Cell juice is then filtered through nylon mesh to yield filtered plant cell juice. 2017213518 10 Aug 2017 5 [0129] Separation of fresh phytomass to cell wall fraction and cell intracellular juice is followed by fractionations of cell juice conducted to produce core BAFSI: membrane and serum fractions.

[0130] Filtered cell juice is exposed to microwave treatment in order to coagulate cell juice. The coagulated cell juice is cooled and then subjected to centrifugation or 0 ultracentrifugation in order to yield membrane fraction and cell juice supernatant.

[0131] BAFSI membrane fraction is used to prepare skin care, sun care, hair care and personal care compositions containing BAFSI membrane fraction.

[0132] Cell juice supernatant “as is” can be considered as suitable BAFSI as well and used as bioactive ingredient. 5 [0133] In addition, cell juice supernatant can be used to prepare skin care, sun care, hair care and personal care compositions containing BAFSI.

[0134] Depending on the marine organisms or plant source, cell juice supernatant can be further subjected to refinement of cell serum to yield stable and active cosmetic ingredients. This is accomplished by removing from the cell serum the major components Ό responsible for the irreversible transformations that lead to generation of unwanted precipitate and deterioration of color and odor. These procedures include, but are not limited to: pH adjustment, isoelectric precipitation, microwave treatment, heat treatment, cooling, centrifugation, vacuum filtration, and stabilization.

[0135] Isoelectric precipitation is used to yield a mixture containing cytoplasm 25 fraction and cell serum fraction. Cell serum fraction is then subjected to microwave treatment to cause coagulation. In order to separate cell serum fraction from cytoplasm fraction, the mixture is subjected to centrifugation. Depending on the plant source, prior to microwave treatment, cell serum fraction can be pH-adjusted. After coagulation, the mixture is then cooled followed by filtration or centrifugation to yield cell serum filtrate. It should be noted 30 that this procedure must be used immediately after separation of cell serum from cytoplasm fraction is completed. The quantitative criteria to evaluate the complete separation of cytoplasm fraction are the absence of detectable levels of high molecular weight proteins (e.g., absence of ribulose biphosphate carboxilase) in subsequent filtrate or supernatant. As an 27 example, the precipitated cell juice supernatants may be separated in a refrigerated centrifuge for greater than or equal to 20 minutes at greater than or equal to 3,000 rpm, and an absence of the proteins having molecular weight of greater than or equal to 10,000 in cell serum achieved. 2017213518 10 Aug 2017 5 [0136] Cell serum filtrate is than stabilized with stabilizers, preservatives, chelating agents and antioxidants to yield cell serum-derived BAFSI.

[0137] Suitable preservatives for use in the present invention include, for example, potassium sorbate, sodium benzoate, sodium methyl paraben, and citric acid. Suitable stabilizers include, but are not limited to, pentylene glycol, ethylhexylglycerin, Suitable 0 chelating agents include but are not limited to tetrasodium EDTA, disodium EDTA, oxalic acid, citric acid, tartaric acid. An example of a suitable antioxidant for use in the present invention is sodium metabisulfite.

[0138] BAFSI are captured and isolated via fresh plant fractionation technologies and are well suited for their utilization in skin care, sun care, hair care and personal care 5 formulations and applications comprising at least one BAFSI and other cosmetically acceptable ingredients and actives.

[0139] The present invention also relates to a method for preparing the BAFSI-containing skin care, sun care, hair care and personal care compositions exhibiting optimal combination of the useful physico-chemical properties and biological activities that include, Ό but are not limited to anti-oxidant and free radical scavenging activities; inhibition of enzymes associated with skin inflammation, skin ageing and environmental damage, skin protection and repair of human tissues.

[0140] Stabilized BAFSI demonstrate properties which fully satisfy all requirements of cosmetic ingredients. Stability studies indicate that cosmetic ingredients produced from 25 cell serum via these methods are stable at room temperature for 12-24 months (i.e., they maintain physico-chemical integrity and activities).

Example 2 30 Preparation of BAFSI serum fractions from Giant brown kelp (Macrocystis pyrifera) [0141] Macrocystis pyrifera starts ranging in size from 15 cm to 60 cm in length were harvested off the Southern California Ocean floor. The starts were immediately bagged after collection with six to seven starts per bag in ocean water, packed in coolers with gel ice packs and shipped via overnight delivery to the laboratory in Ossining, N.Y. The kelp was placed 28 in the aquariums within thirty minutes of delivery and left to acclimate in the circulating aquariums. 2017213518 10 Aug 2017 [0142] Four identical 150 liter aquariums were prepared prior to each shipment to replicate ocean conditions in the kelp’s natural environment. Thirty-five (35) grams per liter 5 of Coralife Scientific Grade artificial sea salt was mixed with deionized water and circulated through the aquariums. Twenty five milliliters of Part A and Part B Proline F/2 algae food was added to each aquarium.

[0143] The ranges of cultivation parameters used for control and stressed systems with Giant brown kelp {Macrocystis pyrifera) were: Control (No stress): Giant brown kelp 0 (Macrocystis pyrifera) harvested from original cultivation conditions in deeper water and processed; Hydrostatic pressure stress only was on-going during all respective cultivation times; Cultivation times were: 72 hrs (3 days) or 96 hrs (4 days). Hydrostatic stress occurs when algae, which typically grow in deeper water (10 ft or deeper), for example, Giant brown kelp (Macrocystis pyrifera), are transferred and then cultivated in more shallow reservoirs 5 (aquariums) with reduced hydrostatic pressure compared to the one existing in original cultivation conditions; Hydrostatic Stress + UVB Stress = 2 mW/cm2 UVB 3-12 hrs/day; Hydrostatic Stress + Ozone Stress = lOOmg/hr continuous injection; Hydrostatic Stress + Osmotic Stress - osmolality of cultivation media = 75% of control.

[0144] Description of cultivation equipment and control system components and the Ό ranges of cultivation parameters used in aquariums are described in Table 1 and Table 2, respectively.

[0145] Biomass samples of Giant brown kelp (Macrocystis pyrifera) were taken upon delivery and removed from the cultivation aquariums at specific cultivation times: 72 hrs (3 days), 96 hrs (4 days). After cutting off and discarding the holdfasts, the following parts of 25 this macroalgae: blades, pneumatocysts and stipes were collected, rinsed and placed in receptacle of Grindomix GM 200 Knife Mill (Retsch, Germany) with stainless steel knife and gravity lid and grinded for 30 seconds at 3000 RPM.

[0146] The grinded biomass was then immediately pressed using a horizontal, continuous screw press (Compact Press "CP-6", Vincent Corporation, FL). The pressure on 30 the cone was maintained at level 24 kg/cm2, screw speed was at 12 rpm, and the temperature increase was < 5°C. As a result, cell wall fraction was effectively separated from cell juice which was utilized for further fractionation. 29 [0147] Initial pH of cell juice was from 6.50 to 7.30. It was adjusted to pH about 4.0 2017213518 10 Aug 2017 and subjected to the microwave treatment at about 194 F (90 °C) for about 30 s., chilled to about 30 C, centrifuged and separated in a refrigerated centrifuge for greater than or equal to 45 minutes at greater than or equal 4,000 g. 5 [0148] The following composition of preservatives and stabilizers was used: potassium sorbate 0.1%; sodium benzoate 0.1%; sodium metabisulfite 0.1%, tetrasodium EDTA (Dissolvine 220S) 0.1% and pentylene glycol (Hydrolite 5) 1.9%.

Modulatory effects of stress factors on the properties of BAFSI serum fractions from Giant brown kelp {Macrocystis pyrifera) [0152] BAFSI from Giant brown kelp {Macrocystis pyrifera) were analyzed to 0 determine the impact of various stress factors on their physico-chemical properties (surface tension; surface modification properties; dry matter; osmolality) and biological activities using enzyme inhibition, anti-oxidant, and free-radical scavenging assays. The results are presented in FIGS. 3-10 and summarized in Table 4. 5 Table 4

Additionally, osmotic 31 stress results in lowest dry matter content, which can be explained by mechanisms of coping with lower osmotic pressure (FIG. 3). 2017213518 10 Aug 2017 [0154] Osmolality follows a somewhat similar pattern to dry matter (FIG. 4).

[0155] However, when comparing the number of particles generated by same amount 5 of dry matter content, the differences are more telling, especially for osmotic stressed kelp.

[0156] It could be that kelp cell components have bound a greater number of particles, decreasing relative osmolality further, or that relatively small particles such as molecules and ions of lower molecular weight have been transported out of the cells (FIG. 5). 0 [0157] Surface tension depends on the concentration and nature of solutes and varies depending on the applied stress factor(s) and simultaneously helps to assess the composition changes due to stress factors (FIG. 6).

[0158] Stresses are capable of altering surface modification capabilities of resulting serum fractions. For example, if a hydrostatic stress is combined with certain UVB stress, 5 BAFSI serum fractions capable of producing lower contact angles could be produced. Skin care products produced with them could therefore have improved skin feel and moisturizing properties (FIG. 7).

[0159] Free radical quenching measurements as measured by DPPH assay show that all stresses result in lower capacity; dramatically lower in case of hydrostatic stress combined Ό with UVB stress. One possible reason would be that at given UVB exposure intensity and total duration much of the available and produced free radical quenching factors have been depleted (FIG. 8).

[0160] All stresses applied, hydrostatic stress alone and combined with osmotic, ozone and UV stresses improve the elastase-inhibiting activity, some very significantly (FIG. 25 9).

[0161] Stresses can induce changes in more specific activities, such as increasing the trypsin-inhibiting activity in case of hydrostatic stress combined with certain UVB stress and reducing this activity under other stress factors (FIG. 10).

[0162] Increase of elastase and trypsin inhibition activity of selected BAFSI from 30 Giant brown kelp (Macrocystis pyrifera) indicates an improvement of their anti-inflammatory and anti-ageing properties. 32

Example 5 2017213518 10 Aug 2017

Comparison of elastase inhibition by BAFSI serum fractions from Giant brown kelp (Macrocystis pyrifera) vs. elastase inhibition by alginate 5 [0163] It is known that alginates are capable of reducing elastase activity, leading to their use in applications such as wound dressings where anti-inflammatory properties are desirable (Influence of alginate and alginate containing silver on elastase and ROS activity in vitro, C. Wiegand et al, Annual Congress 2006 of the ETRS 13.09.-16.09.2006, Pisa/Italy).

[0164] Dry matter of kelp blades contains 17%-25% alginates by weight (Monthly 0 Determination of Alginate, M/G Ratio, Mannitol, and Minerals in Cultivated Laminaria japonica, Masura Honya et al, Nippon Suisan Gakkaishi, 59(2), pp 295-299, 1993).

[0165] To check the contribution of alginate to elastase inhibitory activity of kelp BAFSI, a sample of sodium alginate (Alginic acid sodium salt, from brown algae, A2158) was obtained from Sigma-Aldrich (St. Louis, MO). A solution of sodium alginate in 5 deionized water, 0.2% w/w was prepared by stirring and sonication. A series of dilutions of this solution was tested alongside series of dilutions of two different kelp BAFSI serum fractions according to method for determining elastase inhibition as defined earlier.

[0166] Elastase IC50 of sodium alginate was determined to be 0.0075 mg/ml. In the same test, kelp BAFSI dry matter IC50 was determined to be 0.0012 mg/ml for one serum Ό fraction and 0.0009 mg/ml for another serum fraction. This also corresponds well with the values shown for kelp BAFSI elastase IC50 in FIG. 9.

[0167] The demonstrated difference is significant even with the improbable assumption that kelp BAFSI serum fraction dry matter is composed of 100% alginate. If one takes into account the more likely level of alginate as mentioned above, the difference is 25 dramatic.

[0168] Therefore, elastase inhibitory activity of kelp BAFSI serum fractions dry matter is greater than that of pure sodium alginate which can be explained by the contribution of other components more potent than alginate at inhibiting elastase. 30 Example 6

Thermal stability of elastase inhibitory activity of selected BAFSI serum fractions from Giant brown kelp (Macrocystis pyrifera) [0169] Thermal stability of elastase inhibitory activity of selected kelp BAFSI serum 35 fraction was tested by taking three identical aliquots of the same serum fraction, storing them 33 in identical containers at different temperatures for 6 days and determining their elastase inhibition activity according to the method described above. 2017213518 10 Aug 2017 [0170] Elastase IC50 of the sample stored at 4 °C was 0.0012 mg/ml, IC50 of the sample stored at 60 °C was 0.0012 mg/ml, and IC50 of the sample stored at 80 °C was 0.0011 5 mg/ml.

[0171] Therefore, the elastase inhibitory activity of kelp BAFSI serum fractions can remain stable after exposure to elevated temperatures typically used in thermal stability and accelerated aging studies. 0 Example 7

Preparation of BAFSI serum fractions from Green algae (Chaetomorpha linum) [0172] Green algae (Chaetomorpha linum) are known for their fast growth rate, ability to survive at relatively high temperatures and demonstrate higher levels of 5 photo synthetic activity when compared with giant kelp.

[0173] The Green algae was aqua cultured (Live Aquaria.com Aquaculture Coral &amp; Marine Life Facility, CA.). It was harvested, bagged and shipped via overnight delivery to the laboratory in Ossining, N.Y. The Green Algae was removed from the shipping bags. One portion of Biomass was taken and processed for the Control Day 0 sample. The remainder of :0 the Green Algae was proportioned and placed into the four aquariums all at water temperature of about 25.0 degrees C. within thirty minutes of delivery.

[0174] The ranges of cultivation parameters used for control and stressed systems with Green algae (Chaetomorpha linum) were: Control; UVB Stress = 2 mW/cm2 UVB 12hrs/day; Ozone Stress = 100 mg/hr continuous injection; Osmotic Stress - osmolality of 25 cultivation media = 85% of control; Cultivation time: 24 hrs (1 day), 96 hrs (4 days), 288 hrs (12 days), 456 hrs (19 days).

[0175] Description of cultivation equipment and control system components and the ranges of cultivation parameters used in aquariums are described in Table 1 and Table 2, respectively. 30 [0176] Biomass samples of Green algae (Chaetomorpha linum) were removed from cultivation aquariums at specific cultivation times: 0 hrs, 24 hrs (1 day), 96 hrs (4 days), 288 hrs (12 days), 456 hrs (19 days), rinsed and placed in receptacle of Grindomix GM 200 Knife Mill (Retsch, Germany) with stainless steel knife and gravity lid. The Green Algae was grinded for 30 seconds at 3000 rpm. 34 [0177] The Grinded Biomass was then immediately pressed using a horizontal, continuous screw press (Compact Press "CP-6", Vincent Corporation, FL). The pressure on the cone was maintained at level 24 kg/cm2, screw speed was at 12 rpm, and the temperature increase was < 5°C. As a result, cell wall fraction was effectively separated from cell juice 2017213518 10 Aug 2017 5 which was utilized for further fractionation.

[0178] Initial pH of cell juice varied from 6.30 to 7.90.

[0179] It was adjusted to pH about 4.0 and subjected to the microwave treatment at about 194 F (90 C) for about 30 sec, chilled to about 30 C, centrifuged and separated in a refrigerated centrifuge for greater than or equal to 45 minutes at greater than or equal to 4000 0 g- [0180] The following composition of preservatives and stabilizers was used: potassium sorbate 0.1%; sodium benzoate 0.1%; sodium metabisulfite 0.1%, tetrasodium EDTA (Dissolvine 220S) 0.1% and pentylene glycol (Hydrolite 5) 1.9%. 5 Example 8

The changes in dry matter content of the test articles shown as percentage difference from the control sample taken on the same day are particularly dramatic for osmotic-stressed Chaetomorpha linurn (FIG. 11). 5 [0186] As with kelp, osmolality of BAFSI serum fractions from Chaetomorpha linum follows the similar pattern as dry matter content (FIG. 12). Unlike kelp, the number of particles generated by a given weight of BAFSI serum fractions from green algae dry matter does not fluctuate much with exception of UVB-stressed green algae. This may indicate a different mechanism for stress adaptation for green algae (Chaetomorpha linum) VS. 0 macroalgae (Macrocystis pyrifera ) (FIG. 13).

[0187] Brief stresses regardless of their nature increase the ability of serum fractions to inhibit elastase, especially for UVB and ozone-stressed Chaetomorpha linum (FIG. 14).

[0188] Stresses modulate surface tension of all BAFSI serum fractions from Chaetomorpha linum. Greater durations show significant divergence (FIG. 15)

5 [0189] UVB stress increases the Oxygen Radical Absorbance Capacity of BAFSI serum fraction from Chaetomorpha linum (FIG. 16).
