The release of glutamic acid from the obligate marine psychrophilic bacterium Vibrio marinus MP‐1 under various physical conditions has shown that at least two glutamate pools are potentially present. One, designated amino acid pool one, is loosely bound to the cell and is not found in cells accumulating glutamate by de novo synthesis. The second amino acid pool is more stable and is present in cells that are grown on a minimal salts‐sugar medium.
