Birds that tend to stay on the ground more than the air (i.e. Unlike other bacilli which are predominately aerobic, B. licheniformis is a facultative anaerobe, which explains it's ability to grow in additional ecological niches and environments. . This phenotype classically presents as small, flat, 2- to 3-mm colonies with a concave or indented center. Bacillus licheniformis is a rod-shaped, Gram-positive bacterium. [8] B. licheniformis displays a variety of colony morphologies, with the rough "licheniform" colonies giving the organism its name. Statistical analysis with canonical variates gave four well-separated groups, which represented the four species. Bacillus species can be either obligate aerobes which are dependent on oxygen, or facultative . Feather degrading bacteria may have played an important role in the evolution of molting, and patterns in feather coloration (Gloger's Rule). FIG. Bacillus licheniformis has been reported from ventriculitis following the removal . An arrangement might be two (diplo) bacteria, chains (strepto), or palisades (side-to-side clusters), for example. An arrangement is a microbiological term that refers to species-specific bacteria communities. Color ranges from opaque to white. As Bacillus subtilis biofilms in worm intestines seem to lengthen the worms lifespan, many human users hope for the same effect. FIG. Genome Biol. Irregular form, lobate margin. Among the most important species of bacteria that produce medically importan antibiotics are beloging to the genus Bacillus9. Image 8:The image shows the arrangement of cells, specifically coccus/cocci. Can grow on MacConkey agar and Simmons' citrate agar.

Some toxins produced by B. licheniformis have been shown to cause food poisoning in humans. FIG. Circular form. Generally, most bacilli are predominantly aerobic; however, B. licheniformis is a facultative anaerobe compared to . Feathers are a major by-product of the poultry processing industry that are particularly difficult to degrade. They are often beta-hemolytic. Streptomyces albus cultivated on nutrient agar.
