An Examination of Corynebacterium spp. by Gel Electrophoresis

S ummary . The cell free extracts of 24 organisms of the genus Corynebacterium were examined by starch gel electrophoresis for esterase, catalase and peroxidase activity. The protein components of eleven of these extracts were also detected after electrophoresis in polyacrylamide gel. The results indicate a separation of the members of the genus into distinct subgroups comparable to those obtained by grouping strains according to habitat.
