Interference with sporulation can stimulate the rate of a proteinase synthesis inBacillus megaterium

Bacillus megaterium, in which sporulation was blocked either by mutation or with netropsin, synthesizes during the stationary phase more exocellular proteinase than the sporulating culture. The asporogenic mutant synthesizes the enzyme at a higher rate and for a longer time than does the sporulating population. The culture, whose sporulation was inhibited by netropsin, produces the proteinase at a higher rate, although for only a limited time interval.
