ABSTRACT

The previously characterized bacteriophage SP10 enhanced the frequency of wild-type sporulation by Bacillus subtilis W23 and 3-13. Comparison of SP10 with the spore-converting bacteriophage PMB12 indicated that both bacteriophages significantly increased the sporulation frequency of an oligosporogenic mutant that contained spo0J::Tn917 omega HU261. SP10 and PMB12 caused wild-type bacteria to sporulate in a liquid medium that initially contained enough glucose to inhibit the sporulation and expression of alpha-amylase by uninfected bacteria. SP10 also induced the expression of alpha-amylase in the presence of glucose, whereas PMB12 had no detectable effect. These observations were consistent with the conclusion that SP10 is a spore-converting bacteriophage and that SP10 and PMB12 relieve glucose-mediated catabolite repression of sporulation by different mechanisms.
