Asaccharolytic. Casein is not digested. Utilizes amino acids or peptides; preferred
carbon sources are glutamine, glutamate, serine, and histidine. Ferments casamino
acids to ammonia, acetate, butyrate.
Positive results for H2S production and indole production.
Negative results for H2 production, esculin hydrolysis, gelatin hydrolysis, lecithinase, lipase and urease.
