Ecological research is also being done looking at the interaction between plumage colors and B. licheniformis activity, and the consequences thereof. The ability of B. subtilis to produce bacteriocins peptides that possess antimicrobial activity make it a potential treatment against bacterial infection. Current research try to find the "death kinetics" (2) of these bacteria. The rod shape also helps bacteria glide or move through watery environments and provides regular building block shapes that make biofilm formation easier. FIG.

Bacillus licheniformis is commonly associated with food spoilage and poisoning. I realize that the strains causing these problems were wild strains, not strains studied to be probiotics. The ability of B. licheniformis to form endospores allows it to survive in the harsh environments required to manufacture industrial enzymes, chemicals, and antibiotics. B. licheniformis is also known to cause food poisoning in humans; especially high in contamination rates are products such as raw milk, dairy, vegetables, processed baby foods, and cooked meats.
