Abstract: | It is confirmed by a new method for the determination of d-glutamic acid, that Aerobacter strain A rapidly metabolizes d-glutamic acid, while it only shows feeble metabolic activity towards l-glutamic acid when it is grown on a dl-glutamate-K2HPO4 medium. A specific d-glutamic oxidase is demonstrated in the cell-free extracts of Aerobacter strain A. This enzyme seems to be different from d-glutamic-aspartic oxidase obtained from Aspergillus ustus by the authors, since the former has no activity towards d-aspartic acid. |
