1. by produce the method for at least a non-volatile microbial metabolite with solid form based on the microbial fermentation of sugar, the microorganism strains of producing the expectation metabolite in the method uses and contains the sugar liquors culture medium culturing, and substantially remove the volatile component of fermented liquid subsequently, the wherein said sugar liquors substratum that contains has based on the gross weight of this liquid nutrient medium by weight greater than 20% contents of monosaccharides, and this production that contains the sugar liquors substratum comprises:

  • A1) be selected from the starch source production of grain through abrasive material by grinding;

    AndA2) in waterborne liquid, under the situation that at least a starch liquefacation enzyme exists, liquefy this through abrasive material, use at least a saccharifying enzyme to carry out saccharification afterwards,Wherein, for the purpose that liquefies, with in liquefaction process, adding in the described waterborne liquid continuously or in batches of at least a portion through abrasive material.
