Abstract:Growth of temperature-sensitive mutant Bacillus cereus T JS22-C occurred normally at the restrictive temperature (37 degrees C), but sporulation was blocked at stage 0. The production of extracellular and intracellular proteases and of alkaline phosphatase occurred at 37 degrees C, but the expression of a functional tricarboxylic acid cycle did not. At the permissive temperature (26 degrees C), the mutant sporulated at a slightly lower frequency (60%) and at a lower rate than the parent strain. The oxidation o… Show more
“…Although several spo Ots mutants have been isolated (Leighton 1974;Leighton et al 1972;Lundgren and Beskid 1960;Stelma and Sadoff 1973;Szulmajster and Canfield 1965;Young 1976) it is not clear that any of them belong in Class B since their defects may only be affecting asymmetric septation indirectly.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
