Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing at least one nonvolatile microorganism metabolic product by performing micororganism-fertilization based on sugar.SOLUTION: In the method, a microorganism culture which produces a desired metabolic product is cultivated by using a sugar-containing liquid culture medium containing a monosaccharide content exceeding 20 wt.% on the basis of the total weight of the liquid culture medium, most of volatile components of fertilization liquids are removed, and the pickles are produced by (a1) a step of powdering a starch supply raw material selected from grains, and (a2) a step of liquefying the powdered material in an aqueous liquid under the existence of at least one starch liquefied enzyme, then saccharifying the material by using saccharified enzyme, adding a partial amount of a crushed raw material to the aqueous liquid continuously or in a batch manner, and performing the liquefaction. Related to a solid preparation of the obtained nonvolatile microorganism metabolic product, the method uses the solid preparation as an additive or a supplementary agent to the food of human beings or animals, or fabric, leather, cellose, paper, or for treating the surface the product.
