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.

L. monocytogenes is a Gram-positive bacterium, in the division Firmicutes, named after Joseph Lister. Motile via flagella at 30Â°C and below, but usually not at 37Â°C, L. monocytogenes can instead move within eukaryotic cells by explosive polymerization of actin filaments (known as comet tails or actin rockets).he genus Listeria currently contains 10 species: L. fleischmannii, L. grayi, L. innocua, L. ivanovii, L. marthii, L. monocytogenes, L. rocourtiae, L. seeligeri, L. weihenstephanensis and L. welshimeri. L. dinitrificans, previously thought to be part of the Listeria genus, was reclassified into the new genus Jonesia.
