The two cultures were indistinguishable by tests of radiation (ultraviolet, gamma) sensitivity, growth kinetics and morphology. It is concluded that the interruption of protein and RNA syntheses during active logarithmic growth forced the culture into the stationary phase., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-40-2-185
