This microbe is a member of Group 1b Bacilli known for centrally located oblong spores that do not distend the sporangium. They are catalase positive and ferment carbohydrates without production of gas. They grow well over a wide range of temperatures.
Bacillus subtilis has been a key organism for discovery in the field of molecular genetics and the sporulation process. It has economic value as a “factory” for production of enzymes and chemicals. It is found in the soil, on plants, and in the digestive systems of a wide range of animals. It is not harmful to humans, and in fact may be of value as a probiotic organism in some animals.
