We determined the divergence of some staphylococcal catalases on polyacrylamide electrophoresis gel. The results indicate that all Staphylococcus species used in this study had a single catalase in both exponential and stationary growth phases. Less variation in electrophoretic mobility of the Staphylococcus species suggests that this method is not useful for identification of species. Catalase activities of the seven strains were measured in both exponential and stationary growth phases. It is noteworthy that the catalase activity in exponential growth phase was higher than that in stationary growth phase for the five strains. The others maintained the catalase activity at almost the same level during the entire growth phases
