Definitions
- This invention relates to a method of producing cyanobacteria (green-blue photosynthetic algae), specifically to the development of an artificial process, massive, under controlled conditions, useful for generating metabolites of interest, such as paralyzing toxins, at the level industrial.
- the method is characterized by its efficiency, high performance, simplicity and high profitability.
- Neosaxitoxin and Saxitoxin are components of the so-called paralytic poison, these toxins are produced by dinoflagellates of the genera Alexandrium sp., Pyridinium sp., And Gimnodinium sp. and therefore, they are also sometimes found in filtering bivalve shellfish and carnivorous gastropods contaminated by harmful algal blooms, commonly known as red tides, (Lagos, N. (1998)) Microalgal blooms: a global issue with negative impact in Chile. Biol. Res. 31: 375-386). These ficotoxins, in addition to being produced by dinoflagellates in the sea, are also produced by cyanobacteria in fresh water (green-blue algae photo-synthetic).
- the method proposed in the present application is the continuous culture and under controlled conditions of a cyanobacterium that produces a simple profile of paralyzing phycotoxins. This profile depends on the cultivated species, and includes neosaxitoxin and saxitoxin or Gonyaulatoxins 2 and 3. In addition, this cultivation method includes micro nutrient attachments, allowing the highest production of these pharmacologically active compounds per wet weight of microalgae so far. described.
- Neosaxitoxin, saxitoxin and gonyaulatoxins are compounds that have a basic structure that corresponds to tetrahydropurines and are produced by the cyano-bacteria mentioned as secondary metabolites. These compounds, like all secondary metabolites, are found within the cells but are also released into the culture medium. Thus, two sources of these products are generated: in the fraction of the cell pellet and in the medium where the cyanobacteria are grown.
- Another advantageous feature is the very high production of ficotoxins under the selected culture conditions and procedures, and which are described herein. invention, which makes it possible to define cyanobacteria as the best source of these ⁇ -cotoxins, especially neosaxitoxin in the case of Aphanizomenon (Aph) gracile (Lemm) Lemm, the major component and the one of greatest interest for mass production.
- cyanobacteria as the best source of these ⁇ -cotoxins, especially neosaxitoxin in the case of Aphanizomenon (Aph) gracile (Lemm) Lemm, the major component and the one of greatest interest for mass production.
- This species of cyanobacteria Aphanizomenon (Aph) gracile (Lemm) Lemm is a producer of saxitoxin and mostly neosaxitoxin, and was collected in Lake Crato, a water reservoir in Portugal, isolated and coded as LMECYA 41 and was identified as Aphanizomenon (Aph) gracile (Lemm) Lemm, first based on its morphology and then according to its 16S rRNA gene sequence (Paulo Pereira, et al., 2001. 5th International conference on toxic cyanobacteria, July 15-20, 2001, Queensland, Australia).
- This method of isolating a cyanobacterium and obtaining a pure culture can be applied to any of the other cyanobacteria producing paralytic ficotoxins mentioned above.
- the general objective of the present invention is the massive, continuous and industrial production, under controlled and low-cost conditions of a cyanobacterium mainly producing paralytic phycotoxins such as saxitoxin, neosaxitoxin and / or gonyaulatoxins.
- a specific objective of the invention is the development of an optimized production process, in a kind of monoculture cyanobacteria at a low and commercially competitive cost.
- Another specific objective of the invention is the achievement of an industrial and continuous process, in perpetual form of this strain, as a source of compounds of high added value, not commercially available and with applications in clinical therapy of various pathologies.
- Another specific objective of the invention is the achievement of a continuous culture of this cyanobacterial strain, aimed at favoring the production of fundamentally neosaxitoxin, with a small amount of saxitoxin (one fifth of neosaxitoxin) or fundamental production of gonyaulatoxins 2/3 as a majority and primary component
- Another specific objective of the invention is to achieve high production of neosaxitoxin and / or gonyaulatoxins per cyanobacteria cell.
- the present application presents a method of obtaining and producing massive cyanobacteria through continuous culture.
- the cyanobacteria susceptible to continuous culture are among others:
- Another preferred requirement is a permanent light cycle without darkness, this is also an innovation of this massive culture procedure, since cyanobacteria are photosynthetic organisms and require light, and are kept at their maximum development always in the exponential phase of increase. In relation to this, it is important to note that light and dark cycles of different time ranges can also be used, during the development of this continuous culture, even using the cycles given by natural light.
- Another innovation of the process described in this application is the permanent maintenance of the growing crop in exponential phase and in permanent production of ficotoxins, the latter, making selective and quantified crops, depending on the quantitative development of the crop in each reactor.
- the optimum temperature range, for the growth of these cyanobacteria is within the normal range of environmental temperature variations of a Chaparral-Mediterranean climate such as that of the Central area of Chile (between Arica to Temuco).
- a suitable volume is removed for use, for example, in the purification of a metabolite produced by the cyanobacterium, and the volume removed from the cell culture is replenished, adding an equivalent volume of sterilized medium .
- the filament count over time once a certain development has been reached, another suitable volume of cyanobacteria can be collected again, always maintaining the same final volume of the culture medium, renewing with an equivalent volume of replacement every time collect a certain volume of cells.
- a system of cyanobacteria in culture is thus obtained, as a continuous source of cyanobacterial production.
- the cultivation of cyanobacteria is carried out in appropriate aerated reactors, with permanent agitation and light.
- the light can be artificial, for example, emitted by fluorescent tubes.
- the culture medium considered for the reproduction of cyanobacteria consists of distilled water, mineral salts and micronutrients, all of them sterilized.
- the culture medium is prepared based on the MLA X 40 medium (MLA medium,
- CSIRO marine research CSIRO microalgae research center, Hobart, Australia, for cyanobacterial culture (microalgae @) marine.csiro.au), which contains, among others, the following components MgSO 4 7H2O, NaNO 3 , K 2 HPO 4 , H 3 BO 3 , H 2 SeO 4 , Biotin, vitamin B 12 and thiamine-HCl, EDTA-Na, ferric chloride hexahydrate, carbamate sodium and hydrated manganese chloride, NaHCO 3 , CaCl 2 2H 2 O, CuSO 4 5H 2 O, ZnSO 4 7H 2 O, CoCl 2 6H 2 O, NaMoO 4 2H 2 O.
- the culture medium of the present invention incorporates arginine, methionine and allantoic acid.
- FIGURE 1 Filament production on a culture day considering the culture medium of the present invention (MLA medium modified with methionine, arginine and allantoic acid) under continuous light conditions and unmodified culture medium (Simple MLA medium ) with light cycle: darkness. Best way to realize the invention
- the culture medium comprises between 2 and 3.5 mM final of arginine, between 1 and 2.2 mM of methionine and between 0.7 and 1.3 mM of allantoic acid.
- the preparation of the culture medium is carried out using 'stock' solutions that are prepared separately and sterilized, either by filtration or by autoclave.
- the CSIRO MLA culture medium for cyanobacterial growth is known, however, the complete culture medium described in the present invention considers mineral salts, micronutrients and vitamins that are not found in said medium or in any other publication. regarding the culture of cyanobacteria.
- the cyanobacteria are inoculated in a range of 20 to 40 million filaments per 3 liters of the culture medium of the invention.
- the culture conditions consider constant illumination, provided by fluorescent tubes at a controlled temperature of between 15 to 35 0 C, preferably in a range of between 20 to 25 0 C with an optimum of 22 ⁇ 2 0 C.
- the method of the invention comprises generating an inoculum in a range of 20 to 40 million filaments, this inoculum is developed in small 250 milliliter flasks in a light-dark culture chamber (16: 8 hours) and temperature controlled at 22 ⁇ 2 0 C.
- Aphanizomenon (Aph) gracile (Lemm) Lemm it should be considered that this strain is grown well in the range of 15 - 30 0 C, its optimal conditions being between 22 + 2 0 C .
- Aphanizomenon (Aph) gracile (Lemm) Lemm cells have an already known division cycle of 0.33 per day. This means that in three days the culture doubles its cell mass. This allows, to collect a liter of culture of each reactor of 3 liters, every 1 to 2 days maximum.
- the volume removed from the cell culture is replenished by adding a liter of sterilized medium. The next day or both, according to filament count, another liter of cyanobacteria can be collected again, always maintaining a volume of 3 liters of the culture medium.
- a system of cyanobacteria in culture is obtained as a continuous source of cyanobacterial production in perpetual form.
- the collection of culture medium with cyanobacteria can be conveniently carried out every two days, thus achieving a greater number of filaments.
- Under the conditions of maximum production it is not convenient to space the crop for periods of more than 4 days, since when increasing the concentration of filaments in the crop it deteriorates and there is a decrease in production of ficotoxin.
- the cell pellet corresponds to cyanobacteria forming filaments. These filaments have from 20 to 100 cells and even more cells attached in a filament. That is why they are called filamentous cyanobacteria. When they are 'healthy' and growing very well they form the filaments, because that is where they divide themselves cellularly. This filamentous characteristic is used as a growth control, since it is a positive control of cyanobacterial development. The ability to form filaments allows better control of the contamination of the environment, since when the medium is contaminated and an infection occurs, cyanobacteria do not form filaments.
- the cell pellet is made up of filaments and it is these that are quantified in the inverted phase microscope, since the individual cells are very small, difficult to count and do not exist in a healthy culture.
- the cell-free medium, the centrifugal supernatant is collected to obtain the pellet, the centrifugation is conveniently performed at 10,000 x g x 20 minutes. In this supernatant in soluble form, the ⁇ -cotoxins are also found.
- This supernatant corresponds to the second source of phycotoxins, in good culture conditions, with healthy filaments and without contamination and in the phase of permanent exponential growth, tends to be less than 5% of the total content obtained in the fraction of the pellet .
- the productivity described in the present invention is between 60-125 times higher than the productivity described by Paulo Pereira, et al., 2001, (5th International conference on toxic cyanobacteria, July 15-20, 2001, Queensland, Australia) .
- EXAMPLE 1 Preparation of culture medium [71] For more elaboration of the culture medium, more concentrated 'stock' solutions of micronutrients, mineral salts and vitamins are prepared. All solutions were prepared in distilled water.
- Vitamin Stock (solution A) is prepared according to the indications in the following table: [73]
- micronutrient stock (solution B) was prepared from primary solutions of CuSO 4 5H 2 O (1 gf ⁇ ), ZnSO 4 7H 2 O (2.2 g / 1), CoCl 2 6H 2 O (1 g / 1), NaMoO 4 2H 2 O (0.6 g / i).
- Each reactor of 3 liters capacity was inoculated with the culture medium described in example 1, with 35 million filaments, of Aphanizomenon (Aph) gracile (Lemm) Lemm.
- the reactors were maintained at a controlled temperature of 22 0 C ⁇ 2 0 C, with permanent light provided by fluorescent tubes.
- a third of the total reactor volume (1 liter) was collected and replaced with 1 liter of fresh medium.
- the previous culture had a doubling rate of 0.33 times a day.
- the yields of the present invention are always expressed as a function of the number of filaments obtained, since the presence of filaments (association of many individual cells), is an indicator of the quality of the culture, and in permanent reproduction and development.
- a culture rich in filaments corresponds to a 'healthy' crop and in permanent development.
- the cell pellet corresponds to filament pellet, and from them the purification of phycotoxins begins.
- the cell pellet of each batch corresponds to the volume of one liter of culture collected from each reactor each day. This can also be done every two days, achieving greater number of filaments. Under these conditions of maximum production it is preferable to never harvest for periods of more than 4 days, due to crop deterioration and decreased production of ficotoxin.
- EXAMPLE 3 Comparison of culture with simple MLA medium (unmodified) and modified MLA medium of the present invention.
- Figure 1 shows the difference between a culture of Aphanizomenon gracile in the simple MLA medium (unmodified) and a culture of Aphanizomenon gracile with the culture medium of the present invention, modified MLA. It is easy to appreciate that the modified medium of the present invention, with a final concentration of 2.8 mM arginine, 1.7 mM methionine and 1 mM allantoic acid, is surprisingly superior to culture using the simple MLA medium (unmodified) ).
- Table 2 shows the concentration in the supernatant of the different ficotoxins and the yield per cyanobacterial filament thereof. It also indicates the concentration of filaments per me. of culture medium, according to the method of the present invention.
- Cyano fil cyanobacterial filaments [106] * Cyanobacteria filaments correspond to associations of 20 to 100 cyanobacterial cells. These cyanobacteria form filaments in solution and these are the ones that are counted using inverted phase microscope.
- Table 3 shows different production lots of phycotoxins. It is clearly seen on the average that the yield of ficotoxin per filament is much higher when the modified MLA culture medium is used together with the growth conditions of the present invention, compared to the simple (unmodified) MLA culture medium, which It represents the prior art.
- cyanobacteria are always in logarithmic growth, with 24-hour permanent light and permanently harvesting cyanobacteria, inducing permanent growth, by providing new nutrients in volumes equivalent to the volume harvested in each replacement.
