Method for producing an L-amino acid using a bacterium of the enterobacteriaceae family with attenuated expression of any of the cynT, cynS, cynX or cynR gene or combination thereof

摘要

The present invention provides a method for producing an L-amino acid using a bacterium of the Enterobacteriaceae family, particularly a bacterium belonging to genus Escherichia or Pantoea, which has been modified to attenuate expression of one or more of the cynT, cynS, cynX and/or cynR genes.
