They are currently distributed in various commercial forms. FIG. 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. B. licheniformis produces a protease that can survive at high pH levels. The main objective of this study is to observe the phenol degradation performance by free and immobilized Pseudomonas putida (P. putida) in batch and continuous reactors, respectively. Proteases are often included in detergents, and amylases in the desizing of textiles and sizing of papers. Its optimal temperature for enzyme secretion is 37C. Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques. B. subtilis contains only one double-stranded DNA molecule contained within a circular chromosome. Colonies are described based on size, shape, texture, elevation, pigmentation, and effect on growth medium. It is believed that this bacterium is involved in the evolution of molting and patterns of color in birds due to its feather degrading capability.
