Abstract
The invention relates to recombinant microorganisms which, in comparison to the starting organism, have a higher concentration or activity of a D-amino acid oxidase, of an L-amino acid dehydrogenase, of an NADH cosubstrate regenerating enzyme and, if necessary, of a catalase. The invention also includes methods for preparing L-amino acids from D-amino acids using of these microorganisms.
