I got
- the production of beta-methylmethane dimamine is carried out by using the microorganism Streptomyces nassieuvirensis MD743-GF4 by ordinary microorganisms. By inoculating such a nutrient-containing medium, culturing, and growing under favorable or aerobic conditions, the D-beta-diphenylmethane is mainly contained in the culture medium. By producing and accumulating amines, and further by separating the target substance from the culture, especially the culture broth or culture filtrate. It is.
- a known carbon source or nitrogen source used as a nutrient source for actinomycetes can be used as a nutrient source for actinomycetes.
- Carbon sources that can be assimilated include commercially available carbohydrates such as glucose, galactol, starch, glycerin, maltose, dextrin, sucrose, and lactose. Or soybean oil, fat, etc.
- inorganic salts such as salt, calcium carbonate, magnesium sulfate, manganese chloride, ammonium sulfate, phosphates, and various amino acids can be used.
- D-All night-D-beta-Rigyl tandiamine-producing bacteria can be used, and D-beta-Rigyl tandiamine can be used for production. All materials can be used for cultivation of the above-mentioned MD744-GF4 strain.
- the culture temperature is D.
- the culture temperature is D.
- Culture of the strain MD 7 4 3-GF 4 is usually continued until D-sufficient amount of lysyldiamine is accumulated in the culture. Usually, cultivation of bean is carried out for 2 to 7 days.
- D _ beta-lysinolemethandiamin and its acid addition salts or hydrates are soluble in water, and cultivate D-beta-lysylmethazine diamin-producing bacteria.
- D-beta-lysylmethazinediamine in the liquid portion of the culture is virtually insoluble in organic solvents such as butanol, butyl acetate, and cross-linked form. Treatment with these organic solvents can be used if necessary to remove unwanted compounds or contaminants from the culture filtrate.
- Activated carbon is used as an adsorbent that can be collected by adsorption using various adsorbents for D-base in a culture solution or an aqueous solution. In this case, the adsorbed D-beta-diylmethanediamin is eluted with weakly acidic water and weakly acidic organic, propanol, and acetate water. By this, it is desorbed from the activated carbon.
- D-base-lysylmethazinediamine is adsorbed on the cation-exchange resin in good yield and eluted with a suitable eluent.
- the cation exchangers used for this purpose include amberlite IRC-150, which has a carboxyl group as an active group, and amino-lite CG-150 (Rome-Anne).
- CM - Se off a de-click scan made off Alma shea Co., Ltd. of any H-type, N a type, NH 4
- a positive ion exchange resin such as a mold, or a mixture thereof.
- Antibiotics adsorbed on the cation exchanger are eluted with acidic water, dilute ammonia water and aqueous solutions of inorganic salts in good yields, usually 0.2 N-1 N hydrochloric acid and 0.5 N—2 N ammonia water is used. Since D-beta-methyldiamine diamin does not substantially adsorb to the anion-exchange resin, this means neutralization of the acidic solution containing the compound or acidification from the compound. Can be used to remove contaminants.
