METHOD OF PRODUCING L-ARGININE USING Enterobacteriaceae BACTERIA, CONTAINING DISRUPTED-ACTIVITY N-ACETYLORNITHINE DEACETYLASE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to biotechnology and provides a method of producing an L-amino acid, such as L-arginine, via fermentation using Escherichia bacteria, modified to contain an argJ gene which codes an enzyme having at least ornithine acetyltransferase activity, wherein the bacteria are modified to contain disrupted-activity N-acetylornithine deacetylase.EFFECT: invention enables to obtain L-arginine with high efficiency.10 cl, 2 dwg, 4 tbl, 7 ex
