[Variations in enzyme activities in different sporulation conditions of Bacillus megaterium].

Glucose dehydrogenase and alkaline phosphatase activities have been studied for various conditions of sporulation of Bacillus megaterium KM (carbon, nitrogen, phosphate starvation). Glucose dehydrogenase appears in all conditions of sporulation, even with excess of glucose or gluconate. Alkaline phosphatase, usually dereprimed in phosphate starvation, does not increase during sporulation of Bacillus megaterium when phosphate is present.
