RECA-NEGATIVE AND RHAB-NEGATIVE MICROORGANISM

摘要

The present invention describes new microorganisms specifically for use as expression systems for rhamnose-inducible promoters. Due to the combination of rhamnose and recombination deficiency artificially created in these organisms, expression systems which require less of the expensive rhamnose for induction and therefore can be induced more inexpensively, and have a higher genetic stability are obtained.
