Summary
Two Arthrobacter strains were identified as having high alanine productivity and L-alanine dehydrogenase (ADH) activity upon growth on glucose. They excreted large amounts of DL-alanine (37 and 81 g/1), but Bacillus sphaericus with glucose-repressible ADH did not at all. These results suggest that the glucose-nonrepressible ADH might be involved in alanine overproduction in the Arthrobacter strains.
