This protease prevents shrinkage and fading colors since it allows lower temperatures to be used, which in turn lowers energy use as well. With antibiotic resistance on the increase, new therapies for bacterial infections are receiving a lot of attention. FIG. Endospore formation is actually desired and serves as a great example of prokaryotic development and differentiation. Bacillus Flashcards | Quizlet Bacillus licheniformis Gibson 46 | Type strain - BacDive In the laboratory, naturally-occurring B. subtilis enzymes were able to normalize pH, reduce COD by over 87%, lower TSS by over 90%, and remove nearly 50% of chloride. FIG. The ability of B. licheniformis to form endospores allows it to survive in the harsh environments required to manufacture industrial enzymes, chemicals, and antibiotics. Bacillus anthracis, the etiological agent of anthrax, is a gram-positive, spore-forming rod, with colonies exhibiting a unique ground-glass appearance, and lacking hemolysis and motility.In addition to these phenotypes, several others traits are characteristic of B. anthracis such as susceptibility to gamma phage, the presence of two virulence plasmids (pX01 and pX02), and specific . B. licheniformis is a Gram-positive, rod-shaped, aerobic, endospore-forming organism, which forms colonies of a moderate (2-4 mm) diameter, exceptionally variable in their appearance and often.
