The invention relates to polynucleotides from coryneform bacteria which code for the mdhA gene and comprise polynucleotide sequences, chosen from the group consisting of polynucleotide which is identical to the extent of at least 70 % to a polynucleotide which codes for a polypeptide which comprises the amino acid sequence of SEQ ID No. 3, polynucleotide which codes for a polypeptide which comprises an amino acid sequence which is identical to the extent of at least 70 % to the amino acid sequence of SEQ ID No. 3, polynucleotide which is complementary to the polynucleotides of a), b) or c) [sic], and polynucleotide comprising at least 15 successive nucleotides of the polynucleotide sequences of a), b) or c); and a process for the fermentative preparation of L-amino acids using coryneform bacteria, in which at least the mdhA gene is present in attenuated form, and the use of the polynucleotide sequences as hybridization probes. |
