FERMENTATIVE PRODUCTION OF NON-VOLATILE MICROBIAL METABOLISM PRODUCTS IN SOLID FORM

摘要

The invention relates to a method for production of at least one non-volatilemicrobial metabolism product in solid form by sugar-based microbialfermentation, wherein a microbial strain producing the required metabolismproduct is cultivated with a sugary liquid medium with a monosaccharidecontent of more than 20 wt. %, based on the total weight of the liquid medium,the volatile components of the fermentation brew are mostly removed, thesugary liquid medium being produced by: a1) milling a starch source selectedfrom cereal grains, a2) liquefying the milled material in an aqueous liquid inthe presence of at least one starch-digesting enzyme and subsequentsaccharification using at least one saccharifying enzyme, wherein theliquefying is carried out with addition of a partial amount of the milledmaterial to the aqueous fluid continuously or batch-wise. The inventionfurther relates to a solid formulation obtained by the above method of a non-volatile microbial metabolism product and the use of such a solid formulationas additive or supplement to animal or human food or for textile, leather,cellulose, paper or surface treatments.
