Abstract

We found that Corynebacterium glutamicum ATCC 13032::argF extracellularly produced a large amount of D-ornithine when cultivated in a CGXII medium containing 1 mM L-arginine. This is the first report that C. glutamicum ATCC 13032 or its mutant produces a D-amino acid extracellularly. C. glutamicum ATCC 13032::argF produced 13 mM D-ornithine in 45 h of cultivation.
