ABSTRACT
Nine of ten cultures of Ps. putrefaciens failed to grow in media containing ammonium salts as a source of nitrogen. Certain amino acids, asparagine, numerous complex hydrolyzed proteins, and intact protein materials were utilized. Hydrolyzed proteins afforded the best growth of the test cultures.
One culture of Ps. putrefaciens which utilized ammonium salts, amino acids, and asparagine as a source of nitrogen grew relatively poorly in complex organic nitrogenous materials.
