Description

Pseudomonas alcaligenes ATCC-12815 was used as one of the best strains metabolizing pyrrolidone carboxylic acid (PCA). Each of D-, L- and DL-PCA was well utilized as a sole source of carbon and nitrogen by this strain. Yeast extract was required for the maximal formation of L-glutamic acid and majority (90%) of the added DL-PCA in low concentration was well converted to L-glutamic acid in growing culture.<br> With using the suspension of the cells, L-glutamic acid was also formed in a large amount. Young cells which are exponentially proliferating possessed an intensive activity of L-glutamic acid formation from PCA. In contrast, cells cultured for a longer period possessed less or a little activity. Cell activity of forming L-glutamic acid from PCA was inhibited by the addition of glucose to the preculture or incubation media.
