Bacillus licheniformis is an interesting type of bacteria because it affects humans in many different ways. B. licheniformis is Gram-positive and rod-shaped. It is a motile bacterium, a facultative anaerobe (unlike other bacilli that are typically aerobic), and closely related to Bacillus subtilis.B. licheniformis produces endospores, and is usually found in the soil as spores.It is an apathogenic microorganism that is usually associated with plants and plant materials.t is a motile bacterium, a facultative anaerobe (unlike other bacilli that are typically aerobic), and closely related to Bacillus subtilis.

Bacillus cereus is an endemic, soil-dwelling, Gram-positive, rod-shaped, motile, beta hemolytic bacterium. Some strains are harmful to humans and cause foodborne illness, while other strains can be beneficial as probiotics for animals.he timing of the toxin production was previously thought to be possibly responsible for the two different courses of disease, but in fact the emetic syndrome is caused by a toxin, cereulide, found only in emetic strains and is not part of the standard toolbox of B. cereus.
