发明名称 |
Microorganism with deregulated cysteine metabolism, useful for high-level production of cysteine and its derivatives, has increased activity of the CysB transcription regulator |
摘要 |
The invention relates to a method for production of l-cysteine or l-cysteine derivatives by means of a fermentation with micro-organisms and micro-organisms suitable for said method. The micro-organism strain adapted to fermentative production of l-cysteine or l-cysteine derivatives comprises a deregulated cysteine metabolism which is not dependent upon an altered cysB activity. Said micro-organism strain is furthermore characterized by an elevated cysB activity, whereby the cysB activity comprises a regulation pattern typical for a wild type cysB.
