PDF Identification Of Bacillus Species - Webmail.gestudy.byu.edu (6) It tends to form spores in soil which makes it desirable to be used for the industrial purposes such as the production of enzymes, antibiotics, and small metabolites. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 16: Streptomyces albus morphology (Enlarged view). Since about 80% of the coding sequence of B. licheniformis contain B. subtilis orthologs, it is considered part of the subtilis group. Bacillus cereus produces numerous enzymes and aggressins. This protease prevents shrinkage and fading colors since it allows lower temperatures to be used, which in turn lowers energy use as well. (2012). 47. (9). Bacillus subtilis bacteriocins can affect a much wider range of potentially pathogenic bacteria than the bacteriocins of other, more commonly-used bacteria such as Lactobacillus. milk pasteurization. Researchers culture and isolate this protease to add it into detergents. The organism secretes a keratinase which is capable of complete degradation of a feather within 24 hours, as feathers are made up of 90% keratin. Another use of B. subtilis is in wastewater treatment. Bacillus subtilis, hay bacillus, or grass bacillus was one of the first Gram-positive bacteria to be studied.

Bacitracin lyses the proplasts of B. licheniformis in the presence of cadmium or zinc ions. 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. The bacterium grew to a fractal colony through the diffusion-limited aggregation process, a round colony reminiscent of the Eden model, a colony with a straight and densely branched structure similar to the dense branching morphology, a colony spreading without any openings, and a colony with concentric rings, on plates with various agar and Under good conditions, the spores will germinate and produce vegetative cells. Reports about Bacillus licheniformis having detrimental effects on insect, avian, plant, and estuarine marine species are fortunately almost non-existent. Bacterial colonies are groups of cells belonging to a clone grown either on the surface of the gel-type solid or embedded in it to absorb the nutrients from it. Some toxins produced by B. licheniformis have been shown to cause food poisoning in humans. 19.
