Definitions
- This invention relates to components that, within a matrix, have the ability to aggregate to multidimensional structures, and to organisms containing such components and their use as solute, gas, thermal and UV-barriers in plastic materials and textile, and to thus formed multidimensional structures as carriers of living microbial cells and their use as solute, gas, thermal and UV-barriers in plastic materials and textile.
- This matrix can be an aqueous or a non-aqueous liquid or a polymeric solid material.
- These multidimensional structures can vary from being two-dimensional, e.g. planar, to more complex three-dimensional structures.
- Examples of multidimensional structures are vesicles consisting of one or more closed bilayer shells made of amphiphilic molecules, surrounding an aqueous core. These amphiphilic molecules comprise a hydrophobic and a hydrophilic part. These amphiphilic molecues can be surfactants Typical for vesicle forming surfactants is that the projected surface area of the hydrophobic group is about equal to the projected surface of area of the hydrophilic group. Vescile-forming surfactants are natural, such as phospholipids, or synthetic, such as double-tailed quaternary ammonium halides.
- surfactants can be negatively charged, such as the phospholipid phosphatidyl glycerol, zwitterionic, such as the most abundant phospholipid phosphatidyl choline or positively charged, such as the double- tailed dialkyldimethalammonium halides (Cocquyt, 2005).Petkova et al. (2003) and Platikanov (2003) have investigated the gas permeability of phospholipid bilayers using a very specific bubble diminishing method.
- the polar head groups of archaeal lipids are phospholipids or glycosides that are linked to one of the core lipids.
- the most common phospholipids are phosphoserin, phosphoinositol, phosphoglycerol, phosphoetanolamin and many phosphoglyicolipids, among them the most common carbohydrates found among archaeal lipids are glucose, gulose, mannose, galactose, inositol and A/-acetylglucosamine, which can form mono-, di-, or oligosaccharides on one or both sides of caldarchaeol.
- Phosphoglycolipids with two polar head groups on both sides of the caldarchaeol may have glycerophosphate as the phosphoester moiety on one side and gulose alone or glucose and mannose, which form mono-, di-, or oligosaharides as the sugar moiety on the other side as is in the case of Thermoplasma acidophilum (Shimada et al. 2008). Replacement of one glycerol moiety of the core lipid backbone by a nonitol has also been observed (De Rosa and Gambacorta, 1988).
- ether linkages are more stable than ester over a wide range of pH, and the branching methyl groups help to reduce both crystallization (membrane lipids in the liquid crystalline phase at ambient temperature) and membrane permeability (steric hindrance of the methyl side group).
- Ether lipids are also resistant to enzymatic degradation by phospholipases and archaeal liposomes are exceptionally stable, they do not fuse or aggregate during storage at 4°C over a period of 4 months (De Rosa, 1996).
- the saturated alkyl chains would impair stability towards oxidative degradation particularly in halophiles that are exposed to air and sunlight (Benvegnu et al., 2008).
- the membranes of methanogens and thermoacidophiles essentially consist of bipolar monolayer structures (Table 2).
- the high proportions of glycosylated lipids presented in membranes of thermoacidophiles and methanogenes may further stabilize their membrane structures through the interglycosyl headgroup hydrogen bonding.
- the presence of large sugar heads towards the convex surface of the membrane is likely to promote an asymmetric orientation, thus making the monolayer organization easier.
- lipids in particular planar lipids, more particularly liposomes, lipids were shown to be an excellent source for the formation of liposomes with thermostability and tightness against solute leakage (Gambacorta et al. 1995).
- Membrane stability can be conveniently monitored by determining the release of fluorescent dyes originally trapped in the intravesicular compartment of the liposomes.
- several studies have focused on investigation of membranes made solely from bipolar lipid fractions. Different physicochemical properties, such as structure, dynamics, and polymorphism, thermal and mechanical stability, of bipolar lipid fractions extracted from several archaeal species have been investigated (Chang 1994; Elferink et al. 1994; Yamauchi et al. 1993).
- Arakawa and his coworkers investigated the polymorphism and physicochemical properties of the macrocyclic lipids by synthetic 72-membered macrocyclic tetraether lipids.
- DSC, 31 P NMR and electron microscopy analysis studied the physicochemical features of diphospholipids.
- the cyclic tetraetherlipids appeared to show lower phase transition temperature (T c ).
- Fluorescence studies have shown that the passive proton permeability in bipolar tetraether liposomes isolated from S. acidocaldarius is lower and less temperature sensitive than that in liposomes composed of monopolar diester lipids, although the permeability increases with temperature in all liposomes.
- the invention aims at proposing a polymer product providing a contribution over the known materials and applications considering the drawbacks and shortcomings thereof.
- the invention leads to a polymer product containing beside the polymer also a multidimensional structure.
- the multidimensional structure can be synthetic, it can be derived from a cell membranes of a living organism or it can be a living organism. Further the multidimensional structure can also serve as carrier for a living organism in this polymer product.
- the first aspect of the invention comprises the selection of amphiphilic molecules that have the ability to aggregate to multidimensional structures in an aqueous or a non-aqueous liquid or a polymer matrix.
- amphiphilic molecules can be lipids found in cell membranes of living organisms, but they can also be synthetic compounds like surfactants or polymers.
- the multidimensional structure is typically a microemulsion, an L3 (sponge) phase, a hexagonal or a lamellar structure such as a vesicle or liposome,
- the multidimensional structure can also be a living organism.
- the structure of the cell membrane of living organisms is very similar to the structure of a unilamellar vesicle.
- the multidimensional structure is composed of archaeal lipids.
- the multidimensional structure composed of amphiphilic molecules is used as a carrier for living organisms. This bioaggregate structure is then incorporated in the polymer product.
- Coloring with biological pigments included in the cell wall or membrane of the microbial cells. Additionally coloring prevents oxidation of products in the bottle, due to scavenging abilities of pigments.
- living organisms can be selected from a category known as prokaryotic or eukaryotic vegetative cells and/or a phase of inactive or dormant stage such as sexual or asexual spores or cysts or meristematic clumps.
- said cells, mersistematic clumps or cell dormant stages, encapsulated in liposomes should withstand extremely dry conditions and temperatures well above 100° C and act as permanent oxygen or C0 2 barriers, UV blockers and potentially colorings.
- a reliable, slow and prolonged diffusion of organic molecules can be achieved through said polymers into said liposomes and to the encapsulated microbial cells, being realized, creating in the polymer a moist and fluctuating environment, that could activate slow metabolic microbial processes.
- the composition of the selected liposome as carrier, the selected liposome could or could not be degraded, enabling enlargement of immediate space within the polymer for the selected encapsulated microbial cell, enabling its slight expansion or growth and basic nutrition, creating an active and/or passive barrier for oygen ad other gases permeation.
- the bio component of the liposome - bioagreggates could be a type of yeastwith a dry spore, such as for example Saccharomyces cerevisiae, which would be able to withstand the physicochemical conditions required for the inclusion of liposome-bio-aggregates into the polymer.
- yeast could be pleomorphic yeasts such as Hortaea wasneckii, able to grow as yeast cells, hyphal cells, budding hyphae, spores or meristematic clumps.
- pleomorphic yeasts such as Hortaea wasneckii, able to grow as yeast cells, hyphal cells, budding hyphae, spores or meristematic clumps.
- fungal cells are molds such as Aspergillus spp. and their conidia, sexual spores, hyphal fragments, mycelial strands and dormant structures such as chlamidial cells or sclerotia.
- algal cells could be incorporated into the liposome - bioagreggates, such as Haematococcus or Dunaliella salina, or their spores.
- the bio component could be also a mixture of algal and fungal cells.
- the bio component of the liposome - bioagreggates could be prokaryotic cells such as a type of bacterial cell with a dry spore or endospore, like for example Bacillus spp. or lactic acid bacteria or an archeal cell such as halophilic Halococcus or thermophilic Aerppyrum pernix.
- said living organisms are selected from among the extremophiles.
- said living organisms are selected from among the species Bacillus Subtilis, in particular the one bearing No. ID9698.
- said polymers are selected from among the family of the thermoplastic polymers, in particular from among the family of the polyolefins, or polyesters, more particularly from among the family of the polyethylenes, or polypropylenes, even more particularly polyethylene terephthalate (PET), yet more particularly in the form of PET granules that are coated with living organisms brought to a temperature higher than 260°C during the injection molding process.
- the family of the thermoplastic polymers in particular from among the family of the polyolefins, or polyesters, more particularly from among the family of the polyethylenes, or polypropylenes, even more particularly polyethylene terephthalate (PET), yet more particularly in the form of PET granules that are coated with living organisms brought to a temperature higher than 260°C during the injection molding process.
