METHOD FOR PRODUCING RIBOFLAVIN

摘要

The invention relates to a method and to means for biotechnologically fermentively producing riboflavin (also referred to in the following as vitamin B2), and to means for performing said method, in particular a modified microbial host cell having increased riboflavin production. The invention thus discloses novel methods and means for regulating the expression of enzyme activities participating in the riboflavin production of the host cell.
