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.

Citrobacter freundii are long rod-shaped bacteria typically 1-5 Î¼m in length [1]. Most C. freundii cells are surrounded by many flagella used to move about, but a few are non-motile.cology. Citrobacter freundii are commonly found in the environment, mainly in soil, water, and sewages. They are an indicator of potential contamination of water. They are also found on different organs of diseased animals, including mammals, birds, reptiles, and amphibians [1].
