Amino Acid Composition of Representatives of Eight Bacterial Genera with Reference to Aquatic Productivity

Abstract

Representatives of eight bacterial genera were grown under identical conditions and the harvested, washed cells were analyzed quantitatively for eighteen amino acids using chemical methods. All of the bacteria contained the eighteen amino acids and, although quantitative differences were noted, variation in composition was not great. Cell nitrogen content averaged 11.91% of the dry weight. Some of the nutritional implications of the data are discussed.
