摘要:
This invention relates to a process for the production of L-amino acids using coryneform bacteria, in which the glutamate dehydrogenase gene is amplified.
摘要:
The invention provides a process for the fermentative preparation of L-amino acids using coryneform bacteria, in which the subunit carrying the biotin-carboxyl carrier protein domain and the biotin-carboxylase domain of the nucleotide sequence encoding the enzyme acetyl-CoA carboxylase (accBC gene) is amplified, in particular is overexpressed.
