Positive results for arginine dihydrolase, hydrolysis of esculin, beta-galactosidase. Bacillus licheniformis is a bacterium that is commonly found in soil and bird feathers. The pigment is opaque white with a dry, dull, matte surface toward the outer edge of the colony and raised rhizoid growth throughout the colony. 37. Bacillus megaterium at 37. B. subtilis and a few other bacteria types are abel to use polyethylene as their only carbon (energy) source. Non-pathogenic forms are often used in the biotechnology sector, including Bacillus subtilis. Scientists are currently exploring its ability to degrade feathers for agricultural purposes. Circular form. The bacterium was subcultured by cutting a chunk of the agar containing the organism and placing it in the middle of a TSA plate then incubating for 1 week at 37 C. Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species.The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.

Gram-positive bacilli are rod-shaped, spore-producing species that can survive in extremely harsh environments for long periods. FIG. They are often beta-hemolytic. The protease has an optimum pH at around 9 and 10, which is desirable since it can remove protein-comprised dirt in clothes. The colony morphology of Bacillus spp. Chester. 1 IntroductionBacillus licheniformis is a Gram-positive, endospore-forming, saprophytic organism that occurs in plant and soil (Veith et al., 2004).
