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). Colony Morphology 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. [13], B. licheniformis also shows possible applications in bioremediation, biomineralization, and biofuels as more examples.[13]. Bacillus subtilis is a Gram-positive, rod-shaped bacterium that is the type species of the genus Bacillus, commonly used as a model organism to describe the structure of different species of the genus. Unknown isolate cultivated on trypticase soy agar. Bacillus licheniformis is a bacterium that is commonly found in soil and bird feathers. When grown on common nutrients, it forms a round, milky, rough, yellowish, or translucent colony with jagged edges.
