Abstract
A microorganism strain has a deregulated cysteine biosynthesis pathway that is thereby suitable for fermentative production of at least one substance selected from L-cysteine, L-cystine and thiazolidine. The relative expression of the crp gene is reduced in relation to the expression of the crp gene having a wild-type promoter sequence as a result of mutation of the crp promoter sequence.
