Physiological studies were made of six species of the genus Cellulomonas; namely, C. aurogenes, C. biazotea, C. flavigena, C. gelida, C. rossica, and C. subalbus . Differences in the ability to grow at 37° C. and in lysozyme susceptibility were shown. The proteolytic abilities varied from C. rossica which could utilize only gelatin to C. flavigena which digested eight protein substrates. Dehydrogenase and oxygen uptake studies with 17 substrates indicated the greatest differences in utilization of the salts of citric, succinic, and alpha ketoglutaric acids. Rapid utilization of these by C. flavigena, C. rossica and C. biazotea indicated the probable presence of Kreb's cycle of oxidative metabolism in these organisms.
