Toxigenic Strains of Bacillus licheniformis Related to Food Poisoning.Appl Environ Microbiol. B. licheniformis produces a protease that can survive at high pH levels. It is found on bird feathers, especially chest and back plumage, and most often in ground-dwelling birds (like sparrows) and aquatic species (like ducks). Chester. SC-1. The desirable properties of this protease are its prevention of clothes shrinkage and fading colors due to its capability to be used at lower temperatures. The mucoid phenotype is due to the presence of a thick polysaccharide capsule. Circular form. Its optimal growth temperature is 50C, but it can also survive at much higher temperatures.
