[Variations of enzymatic activities in an asporogenic mutant of Bacillus megaterium for various nutritional deficiencies].

An asporogenous mutant of Bacillus megaterium KM, blocked at stage I of sporulation, is cultivated in different conditions which usually lead to sporulation (Nitrogen, carbon, phosphate starvation). Aklaline phosphatase appears only in inorganic phosphate starvation like the wild type, but a glucose dehydrogenase activity also appears in phosphate starvation and so, is dissociated from sporulation.
