Microorganisms and method for L-arginine production by fermentation

摘要

The present invention relates to a microorganism having an L-arginine producing ability, said microorganism being a microorganism synthesizing L-arginine through the biosynthetic linear or cyclic pathway, and bearing a recombinant DNA comprising a gene argJ coding for an enzyme having an ornithine acetyltransferase activity. It also relates to a method for producing L-arginine comprising the steps of cultivating the microorganism as defined above.
