B. Licheniformis

Bacillus licheniformis is a bacterium commonly found in the soil. 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). It is a gram-positive, mesophilic bacterium. Its optimal growth temperature is around 30°C, though it can survive at much higher temperatures. The optimal temperature for enzyme secretion is 37°C. It can exist in spore form to resist harsh environments, or in a vegetative state when conditions are good.xins
