の価値が高まりつつある。The red pigment astaxanthin is a type of carotenoid pigment that is widely distributed in the animal kingdom. Astaxanthin is responsible for the red color of crustaceans such as crabs and shrimp, and in the seafood industry, crab and shrimp shells are used to give the red color to sea bream, Nishikigoi, and shrimp. For a long time in the food industry, shrimp and crab have been added to foods such as Senbei, either as they are or as a powder, to add flavor and color, and recently they have also begun to be used in noodles, bread, etc. In both cases, astaxanthin is effective in increasing color by one color. Furthermore, although astaxanthin does not have the same vitamin A efficacy as β-carotene, it has recently been confirmed that it has a stronger immunostimulatory effect and tumor elimination (reduction) effect than β-carotene, and its value as a useful pigment is increasing. be.

た動物や人が利用(食)しやすいものではない。However, the shells of crabs, shrimp, krill, etc. are currently used as natural resources for astaxanthin, but the astaxanthin content contained in these is low, with 0.1 to 0.5 g of astaxanthin per 1 g of dry matter. Moreover, it is not something that animals or people can easily use (eat).
一方、緑藻類は通常アスタキサンチンは含有しないか、
含有しても極めて微量であることが定説になっている。On the other hand, green algae usually do not contain astaxanthin or

Ccus) is known to contain a large amount of astaxanthin (2 mg/g) in N-deficient culture, and has been experimentally cultured and reported to be effective as color-enhancing feed for shrimp and sea bream. In addition, the green algae Chlorella and Scenedesmus, which are currently cultivated in large quantities and used as food, are known to biosynthesize astaxanthin if cultured in N- or magnesium-deficient cultures, and the astaxanthin content at this time is approximately 0. .5 to 1.5 mg/g.

ことはできず、工業的な利用には適していないという問
題点があった。However, the content of astaxanthin contained in green algae cultured by the above method cannot necessarily be said to be high, and there is a problem that it is not suitable for industrial use.
この発明の目的は、上記問題点を解決するため、簡単な
培養方法により、アスタキサンチンを高濃度に含有する
緑藻類の生産方法を提供することである。An object of the present invention is to provide a method for producing green algae containing astaxanthin at a high concentration by a simple culture method in order to solve the above-mentioned problems.
この発明は、アスタキサンチンを生合成する緑藻類を、
ナトリウム塩、カリウム塩およびルビジウム塩から選ば

を特徴とするアスタキサンチン高含有緑藻類の生産方法
である。This invention uses green algae that biosynthesize astaxanthin.
This is a method for producing green algae with a high content of astaxanthin, which is characterized by culturing in a medium containing 0.2 to IM of one or more selected from sodium salts, potassium salts, and rubidium salts.
本発明において培養の対象となる緑藻類は、アスタキサ

もアスタキサンチンは生合成されない。Table 1 Algae other than green algae, such as Spirulina (blue-green algae), an edible algae that is produced in large quantities, and so-called marine chlorella (taxonomically speaking, it is not a green algae but a different algae from chlorella) are both N-deficient. Astaxanthin is not biosynthesized by culture or the culture method of the present invention.

本発明では上記のようなアスタキサンチンを生合成する
緑藻類を、ナトリウム塩、カリウム塩およびルビジウム
塩から選ばれる1種以上の塩を0.2〜IM含む培地中
で培養することにより、アスタキサンチンを生合成させ
、高濃度にアスタキサンチンを含有する緑藻類を生産す
ることができる。In the present invention, astaxanthin can be biosynthesized by culturing the green algae that biosynthesize astaxanthin as described above in a medium containing 0.2 to IM of one or more salts selected from sodium salt, potassium salt, and rubidium salt. It is possible to produce green algae containing astaxanthin at a high concentration.
上記の塩としては、塩化物、硝酸塩、硫酸塩などがあげ
られる。Examples of the above salts include chlorides, nitrates, and sulfates.
緑藻類の培養方法は、従来よりクロレラ、セネデスムス
等の培養に採用されている方法が適用可能である。As a method for culturing green algae, methods conventionally employed for culturing Chlorella, Scenedesmus, etc. can be applied.
クロレラやセネデスムスの大量培養は光(太陽光)照射
下で行われているのが大部分であるが。Most of the mass cultivation of Chlorella and Scenedesmus is carried out under light (sunlight) irradiation.
全く光を必要としない従属栄養培養も可能である。Heterotrophic culture, which requires no light at all, is also possible.
前者は開放攪拌培養、後者はタンク培養と一般に呼ばれ

殖速度ははるかに低下する。このためアスタキサンチン
の生合成は促進されるが、生産量では緑藻の増加は期待
できない。したがってまず通常使用される培地(窒素源

ム塩、ルビジウム塩等を0.2〜IM濃度で添加し、培
養を続けるのがよい。The former is generally called open agitation culture, and the latter is generally called tank culture, but the present invention can be applied to either type of culture. If sodium salts, potassium salts, rubidium salts, etc. are added to the 0.2 to IM medium during these cultures, the growth rate of Chlorella, Scenedesmus, etc. will be much lower than in normal culture. As a result, astaxanthin biosynthesis is promoted, but an increase in green algae cannot be expected in terms of production. Therefore, first, a commonly used medium (known medium containing nitrogen source, phosphoric acid source, potassium, magnesium, iron, and other trace metal elements) is used, and open agitation culture is performed using carbon dioxide gas, acetic acid, glucose, etc. as a carbon source. Alternatively, it is preferable to carry out mass culture by tank culture, and then add sodium salt, potassium salt, rubidium salt, etc. at a concentration of 0.2 to IM, and continue culturing.

れによりアスタキサンチンの生合成は若干促進され、培
養日数の短縮がみられる。Within four days, green algae such as Chlorella and Scenedesmus begin to contain astaxanthin at a high concentration, and the culture solution turns red. At this time, it is also possible to combine a nutritional deficiency state such as nitrogen deficiency or magnesium deficiency, which slightly accelerates astaxanthin biosynthesis and shortens the number of culture days.
こうして生産されたアスタキサンチン高含有緑藻類はア

いは藻体からアスタキサンチンを抽出して利用される。The astaxanthin-rich green algae produced in this way contains astaxanthin from 4 to lo+sg/g, which is 4 to 10 times higher than that of the nutrient-deficient culture. The obtained algae is treated in the same manner as conventional algae treatment and used as is as algae containing high astaxanthin content, or astaxanthin is extracted from the algae and used.
以上の通り、本発明によれば、アスタキサンチンを生合
成する緑藻類を特定の塩類を含む培地で培養するように
したので、簡単な培養法により。As described above, according to the present invention, green algae that biosynthesize astaxanthin are cultured in a medium containing specific salts, so that a simple culture method can be used.
