- the target substance of the method of the present invention is a substance that is expected to have many physiological activities such as anticancer effects, but in the conventional method, the supply is unstable because the raw material depends on fish oil. Quality is not constant. In addition, many processes and costs are required for purification to remove the smell peculiar to fish oil, but nonetheless, it is difficult to use because the smell peculiar to fish oil cannot be sufficiently removed. There is a problem that products are expensive due to the need for technical issues.
- An object of the present invention is to provide a method for stably and inexpensively producing docosahexaenoic acid using raw materials other than fish in order to solve these problems.
- an algal strain of marine microalgae that is capable of industrially producing and supplying docosahexaenoic acid stably at a constant quality.
- the algae strain in the presence or absence of a surfactant and Z or an antifoaming agent, in the absence of a liquid ( «culture, liquid deep aeration stirring culture and Z or aeration stirring culture Dramatically increases the content of docosahexaenoic acid in the algal cells, further increases the algal cell productivity, and stably reduces the cost of docosahexaenoic acid by extracting docosahexaenoic acid from the resulting algal cells.
- a manufacturing method has been found.
- marine microalgae which had been grown only by the stationary culture method, were subcultured in the presence of a surfactant and / or an antifoaming agent, and were then subjected to an antifoaming agent-resistant strain or a surfactant-resistant strain.
- Successful production of algal cells at a high concentration by liquid shaking culture or liquid deep aeration agitation culture and / or aeration agitation culture in the presence of surfactant and Z or defoamer did.
- the present inventors controlled the inoculum amount of the seed mother to a constant amount, and controlled the stirring peripheral speed to a certain value or less, thereby separating single cells from defoamer-resistant strains or surfactant-resistant strains.
- Algal strains were selected and bred successfully by repeated cultivation and cultivation, making it possible to dramatically increase productivity.
- Cryptocordium 'Ko-121' has been difficult to culture except for stationary culture, because marine microalgae are killed by shearing of cells when agitating with a stirring blade.
- Matec showed that DHA can be produced using agitated culture. But productivity is still not enough.
- various surfactants and / or defoamers used for microbial fermentation are sensitive, and it has been difficult to obtain DHA stably at a high concentration.
- the present inventors succeeded in discovering and breeding Cryptocodinium 'co-121 algal strains that can withstand these by repeating single cell isolation and culture adaptation of resistant algal strains capable of growing. This is what made the light.
- the content of docosahexaenoic acid in the lipids of the marine microalgae provides a medium composition and culture conditions that can be increased. Furthermore, it was found that culturing marine microspheres in a medium in which a surfactant and Z or an antifoaming agent were present increases the algal cell growth and the content of docosahexaenoic acid in lipids. The present invention has been reached.
- the algae used in the present invention belong to marine microalgae, and in particular, algae belonging to Cryptocedinium ii.
- These are known algae, for example, available from storage institutions such as ATCC (American Type Culture Collection), and exemplified by Crypthecodinium cohnii ATCC 30021. 30543, 30556, 3057U 30572, 30775, 50051.50053.50055, 50056, 50058.50060. can do.
- Crypthecodinium cohnii ATCC 30021 is preferable because of high DHA productivity.
- an algal cell strain obtained by breeding as a surfactant-resistant and Z- or antifoam-resistant algal cell strain by repeated single cell separation and conditioned culture.
- a cultured alga body is diluted with a 2% physiological saline solution to a concentration of 10 2 to 10 3 times, and this is diluted with 2% glucose, 0.2% yeast extract, and the interface.
- Catch the resulting colonies and add surfactant and Z or antifoam The algae strain produced by shaking culture in the containing liquid medium is removed, and the same operation is performed again.
- algal strains obtained by selecting an algae strain that is resistant to shaking culture and resistant to surfactant and Z or an antifoaming agent and that has a high ability to produce docosahexaenoic acid.
- the culture is cultivated, and the same operation is repeated 5 to 10 times to obtain and breed an antifoam-resistant and Z- or surfactant-resistant strain.

- the dissolved oxygen content can be about 2 to 50%, but if it is less than 2%, the growth will be slow, and if it exceeds 50%, the algal body yield will be reduced.
- the peripheral speed of the stirring blade is 250 cm / sec. It is preferred that: When the peripheral speed of the stirring blade is more than 250 cm / sec, the cells of the marine microalga alga are sheared and many of the alga are killed, and the proliferation is extremely reduced, which is not practical.
- the cultivation can be performed at a temperature of 15 to 34, but an optimal temperature is 25 to 32 ° C.
- the pH should be around neutral, and the number of culture days should be determined according to the remaining amount of carbon source and the amount of secretion into the medium, but it is usually about 2 to 12 days.
- a surfactant such as a fatty acid ester, a defoaming agent such as a silicone, or a mixture thereof
- the surfactant include glycerin mono fatty acid esters and the like, and examples thereof include glycerin monostearate, glycerin monostearate, glycerin monopalmitate, glycerin monolinolate, and sorbitan monostearate as the sorbitan fatty acid ester.

- the surfactant and / or antifoaming agent is present in the medium at a concentration of 0.01 to 1.0 g / L, preferably 0.05 to 1.0 g / L. If these concentrations are less than 0.01 g / min, the effect of adding surfactant and Z or antifoam is extremely low. If the concentration exceeds 1. Og / L, the effect of adding a surfactant and Z or an antifoaming agent can be obtained, but the efficiency of the recovery of algal cells and the purification of docosahexaenoic acid decreases, which is not preferable.
- the addition of a surfactant and Z or an antifoaming agent to the culture method of the present invention can be used for the culture of marine microalgae used in the present invention, since the strain may be killed. It was unknown whether it could be applied.
- the addition of a surfactant and Z or an antifoaming agent not only suppresses foaming but also increases the algal body yield by 20 to 30% compared to the conventional method, If good, increase by 50% and allow stable culture. Furthermore, with the increase in algal cells, the yield of DHA can be increased by 20 to 30% and more preferably by 50% compared to the conventional method.
- the amount of the culture solution added to the initial medium of the main culture is 1.5 to 20% by weight relative to the initial medium (about 1.5 to 20 ml per 100 ml of the initial medium). ) Is preferred. If the amount is less than 1.5% by weight, a sufficient amount of algal cells cannot be obtained. If it exceeds 20% by weight, the final algal body concentration per unit time will be almost constant. Culture efficiency is not good.
- the algal cells are collected from the culture solution by a general centrifugation method.
- the temperature is preferably lower than the culture temperature, for example, 5 to 15 ° C, 50,000 to 12 Performed by centrifugation at 100,000 xg for 10-15 minutes.
- the collected algal cells are converted into wet algal cells as raw algae or dried algal cells by freeze-drying, heating and ventilation drying.
- Docosahexaenoic acid can be extracted from this algal body. Furthermore, lipids can be extracted from wet algal cells or dry algal cells, and crude lipids containing high levels of docosahexaenoic acid can be extracted and used. Extraction and purification of docosahexaenoic acid from algae are carried out by adding an antioxidant for fatty acids, such as sodium tocopherol, or using an organic solvent such as methanol and chloroform in a nitrogen stream. It can be performed by a method of extracting lipids by a suitable extraction method, or a purification method of Folch, Lees, Stanley et al.
