[The effect of a cationic surface-active substance (catamine AB) on the physiological-morphological properties of B. cereus and E. coli].
Catamine AB (0.05-0.5%) promotes transfer of B. cereus st 96, and E. coli st. 906 cell cultures into metabolic rest. Detergent-treated cells have no energetic metabolism and autolytic processes, have high light-scattering coefficient, and peculiar ultrastructural organization. Viable cells can be observed in the detergent-treated cell suspension after 1 year of incubation. Difference in action of different catamine AB concentrations on stationary and exponential B. cereus cells has been revealed.
