Studies on the Metabolism of D-amino acid in Microorganisms

Part. I. Degradation of D-glutamic acid in Genus Aerobacter

Abstract

Oxidatie metabolism of D-glutamate by microorganism was investigated. It was found that several isolated strains of bacteria belonging to the genus Aerobacter could metabolize D-glutamate more rapidly than the L-form even when they were grown in the DL-glutamate medium. Pure L-glutamic acid could be successfully obtained from the DL-form by decomposing D-glutamic acid using one of these strains. From several experimental results, the occurrence of a specific oxidase responsible for the oxidation of D-glutamic acid was suggested.
