There is an increased interest in using a protease isolated from Bacillus licheniformis in laundry detergents. Shape A bacterial colony can manifest in various shapes which include but not limited to the following: Spiral Bacteria that are twisted or helical in shape which looks like little corkscrews. Two of the species used as probiotics are B. licheniformis and B. subtilis. ducks) are common carriers of this bacterium; it is mostly found around the bird's chest area and back plumage. Although B. licheniformis often occurs in high numbers in these foods, it's presence is not usually regulated in contrast to B. cereus, which is credited with most food poisoning incidents by the Bacillus species. B. licheniformis, although usually associated with the gut and gastrointestinal tract, can also cause distress in other parts of the body. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 19: Mycobacterium marinum morphology (Enlarged view). ducks) are common carriers of this bacterium; it is mostly found 42.
