Coryneform bacterium in which the metD gene is attenuated, in which the metD gene comprises a polynucleotide that a) is at least 70% identical to a polynucleotide encoding a polypeptide comprising the amino acid sequence of SEQ ID No 2, or b) encodes a polypeptide comprising an amino acid sequence that is at least 70% identical to the amino acid sequence of SEQ ID No. 2, and the polypeptide has transcriptional regulatory activity in which the Attenuation is achieved - using a weak promoter, - using an allele that encodes a protein with low activity, or - inactivating the gene. |
