Abstract

Nucleotide sequences from coryneform bacteria which code for the cysD, cysN, cysK, cysE and cysH genes and a process for the fermentative preparation of amino acids using bacteria in which the genes mentioned are enhanced, a process for the fermentative preparation of L-amino acids using coryneform bacteria in which at least the cysD gene, the cysN gene, the cysK gene, the cysE gene and/or the cysH gene is present in enhanced form, and the use of polynucleotides which contain the sequences according to the invention as hybridization probes and a process for the preparation of an L-methionine-containing animal feedstuffs additive from fermentation broths.
