Some Morphological and Physiological Properties of Microbacterium thermosphactum

Abstract
SUMMARY: The properties of strains of Microbacterium thermosphactum obtained from various sources were investigated. All exhibited pleomorphism and occurred both as coccobacilli and as long rods. The change from one morphological form to another was followed by means of slide culture techniques. Electron micrographs of thin sections of M. thermosphactum were also examined. The medium and incubation temperature influenced the catalase and benzidine reactions. The practical implications and the possible taxonomic significance of the results are discussed.
