【発明の詳細な説明】
(産業上の利用分野)
本発明は微生物の培養が効果的になされ得る微生物培養
用発泡体に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a foam for culturing microorganisms that can effectively culture microorganisms.
(従来の技術)
微生物の培養には、液内培養法のほかに、米ふすまなど
を用いる固体培養法がある。目的生産物(例えば、菌体
9代謝生産物など)の種類により。(Prior Art) In addition to the submerged culture method, microorganisms can be cultured using a solid culture method using rice bran or the like. Depending on the type of target product (for example, bacterial cell 9 metabolic products, etc.).
液内培養法や固体培養法が単独で、あるいは組み合わせ
て用いられている。しかし、液内培養法では、培養によ
りベレットが形成され、それにより微生物の培養効率が
低下する。固体培養法では微生物により生産された生産
物の分離が困難である。Submerged culture methods and solid state culture methods are used alone or in combination. However, in the submerged culture method, pellets are formed during culture, which reduces the culture efficiency of microorganisms. With solid state culture methods, it is difficult to separate products produced by microorganisms.
このような欠点を解決するために1発泡体に培地を担持
させ、培養を行う方法が提案されている。In order to solve these drawbacks, a method has been proposed in which a single foam is made to carry a medium and culture is carried out.
例えば、特公昭55−36313号公報には、スポンジ
などの発泡体に培地液を含浸した後、静置培養する方法
が開示されている。しかし、この方法では。For example, Japanese Patent Publication No. 55-36313 discloses a method in which a foam such as a sponge is impregnated with a culture medium and then cultured stationary. But with this method.
発泡体への培地液の含浸が困難である。しかも。It is difficult to impregnate the foam with the medium solution. Moreover.
含浸量には限界があり、市販のポリウレタン発泡体で3
0〜50%、含浸性の良好な発泡体でも90%までであ
る。従って、微生物に対し充分な培地が供給され得ず、
微生物の培養が効果的になされない。There is a limit to the amount of impregnation, and commercially available polyurethane foam has a limit of 3.
0 to 50%, and up to 90% even for foams with good impregnability. Therefore, sufficient culture medium cannot be supplied to microorganisms,
Microorganisms are not cultured effectively.
このような発泡体は、保水力に乏しく乾燥しやすいため

No. 878) and a hydrophilic foam in which bebutide matrix is formed in the molecule (Japanese Patent Publication No. 53-11316)

養されるため、微生物の培養効率が低い。However, in these foams, the solid content and fats and oils in the medium components are adsorbed by the foam, so the medium does not penetrate into the inside of the foam. Therefore, since microorganisms are cultured only on the surface of the foam, the efficiency of culturing microorganisms is low.

の発明者の知見にもとづいて完成された。(Means for Solving the Problems) The present invention provides a medium solution in one foam matrix by mixing and foaming medium components in one foam composition, instead of the conventional method of impregnating two foams with a medium solution. Due to the incorporation of components, cultivation can occur not only on the surface of the foam, but also inside the foam, thereby allowing effective cultivation of microorganisms. It was completed based on the inventor's knowledge.

生し1発泡を促進する。The medium components are primarily physically incorporated into the foam matrix during foaming of a foam composition. However, if, for example, the medium component has amino or carboxyl groups and the foam composition has isocyanate groups, the medium component and the foam matrix will chemically react. Thereby, the medium components are chemically supported within the foam matrix by urea bonds and acid amide bonds. The hydroxyl groups of the medium components react with the isocyanate groups to generate carbon dioxide gas and promote foaming.

発泡させて得られる。Examples include diphenyl diisocyanate, naphthalene diisocyanate, xylene diisocyanate, butane diisocyanate, and triphenylmethane-4,4'', 4''-triisocyanate. Polyether or polyester is reacted with an isocyanate compound to form a prepolymer, and by reacting this prepolymer with water, carbon dioxide gas is generated and foamed to form polyurethane foam. Polystyrene foam is formed by adding a blowing agent (pentane, hexane, heptane, etc.) to a polystyrene prepolymer and emulsion polymerizing it in water. Vinyl chloride foam can be obtained by a pyrolysis method or a gas blowing method. A polystyrene foam is obtained by adding a foaming agent such as petroleum ether or gas Freon 12 to a polyethylene prepolymer, kneading the mixture, and foaming the mixture by heating.

反応が遅延し、所望の発泡密度の発泡体が得られない。If the foam matrix is polyurethane foam,
Medium components are added to a prepolymer (a reaction product of polyether or polyester and an isocyanate compound), water and other blowing agents, and the mixture is subjected to one reaction. Water-soluble medium components are mixed with the prepolymer in an aqueous solution. The water-insoluble medium components are dispersed in the aqueous solution of the prepolymer. The amount of water is preferably in the range of 10 to 100 parts by weight based on 100 parts by weight of the prepolymer. If it is less than 10 parts by weight, the foaming reaction will be delayed and a foam with the desired foam density will not be obtained.

培地成分が発泡体マトリックス内に取り込まれにくい。The reaction between the prepolymer and the medium components and the support of the medium components into the foam matrix are also insufficient. When the amount exceeds 100 parts by weight, the reaction between water and prepolymer takes priority and the medium components are difficult to be incorporated into the foam matrix.
