The Utilization of Carbon Compounds by Some Actinomycetales as an Aid for Species Determination

Abstract
27 isolates of organisms belonging to the genera Streptomyces, Nocardia, and Micro-monospora were tested for their ability to utilize 33 compounds as a source of C in a chemically defined medium. The results obtained with the antibiotic-producing streptomycetes and others indicate that such reactions can aid species identification. All of the streptomycetes studied were found to utilize d-glucose, d-mannose, starch, dextrin, and glycerol, but not erythritol, phenol, o-cresol, w-cresol, p-cresol, Na-forraate, Na-oxalate, and Na-tartrate. Reactions on the other C compounds varied with the particular species.
