METHOD FOR PRODUCING L-ARGININE USING BACTERIUM OF THE FAMILY ENTEROBACTERIACEAE HAVING N-ACETYLORNITHINE DEACETYLASE WITH DOWNREGULATED ACTIVITY

摘要

The present invention describes a method for producing L-amino acid such as L-arginine by fermentation using a bacterium of the family Enterobacteriaceae, particularly a bacterium belonging to the genus Escherichia, which has been modified to contain the argJ gene, encoding an enzyme having at least an ornithine acetyltransferase activity, and the attenuated or inactivated the argE gene encoding N-acetylornithine deacetylase.
