Proteolytic activity of Bacillus subtilis PS-216 wild type and ΔcomQ, degQ::tet, and ΔcomQ degQ::tet mutants on skim milk agar. Photos were taken on a dark blue background after 16 h of incubation at 37°C. Note the clearing zone around the wt colony, indicating the proteolysis of skim milk. Colonies of the mutant strains did not degrade skim milk as much and thus the clearing zones are less apparent.
