A PROCESS FOR THE FERMENTATIVE PREPARATION OF D-PANTOTHENIC ACID AND/OR ITS SALTS

摘要

The invention provides a process for the fermentative preparation of D-pantothenic acid and/or its salts or feedstuffs additives containing these by the fermentation of microorganisms from the Enterobacteriaceae family in particular those which already produce D-pantothenic acid, wherein the nucleotide sequence(s) coding for the glyA gene is enhanced in the microorganisms, in particular is overexpressed.
