title: Sporulation promoting factor in vegetative cells of Bacillus subtilis.
abstract: A simple experimental system for detection of sporulation promoting factors was presented. This system showed that there was a sporulation promoting factor in the vegetative cells of Bacillus subtilis cultivated on nutrient agar for 9 hr (at stage T0). The factor was partially purified from the sonicate of vegetative cells by ethanol fractionation, gel filtration, chromatography and preparative gel electrophoresis, and it was identified as manganese-containing protein.
