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.

Most Gram-positive bacilli encountered in clinical specimens represent normal flora which are contaminants, including members of the genera Bacillus, Lactobacillus, and Corynebacterium.he lactobacilli are nonsporulating, Gram-positive bacilli classified in the large family Lactobacillaceae. Often they are found as long, slender Gram-positive rods in long chains. Usually they are contaminating commensals that are readily recognized from colony morphology and the fact that they are catalase-negative.
