The protease has an optimum pH at around 9 and 10, which is desirable since it can remove protein-comprised dirt in clothes. Bacillus firmus. It is an apathogenic soil organism that is mostly associated with plant and plant materials in nature. FIG. FIG. 49. 33. Bacillus licheniformis was found to be the only isolate in 3 cases of bovine abortion. The water droplets (exudate) that can be seen on the outer edges of the colony, not in the center, is a result of respiration. FIG. 6.

This bacterium, although detrimental, can be modified to become useful. Sequencing of the 16S rDNA of the isolates followed by BLAST search revealed that nine strains could be identified as<i> Bacillus licheniformis</i> and one . Bacteriocins can withstand broad fluctuations in temperature and slow the growth of or even destroy colonies of other types of bacteria. Specific strains are also used to produce peptide antibiotics like bacitracin and proticin, as well as some specialty chemicals, including citric acid, inosine, inosinic acid, and poly--glutamic acid [1]. 35. There are various types of bacteria and each type produces differently looking colonies. 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.

It is found on bird feathers, especially chest and back plumage, and most often in ground-dwelling birds (like sparrows) and aquatic species (like ducks). microbial colonies that showed mucus morphology were streaked on TSA plates to obtain pure cultures. Wastewater Bioaugmentation and Biostimulation. 47. (9). It was found in the fetal stomach contents showing it was able to enter the bloodstream of the adult and cross the placenta to a bovine fetus.

The image below shows how Gram-positive bacteria have a much thicker peptidoglycan layer (in purple). The toxins produced by B. licheniformis can cause damage to cell membranes, deplete cellular ATP, and cause the acrosome to swell; it is not found to have any damaging effects on the mitochondria. [6][10] There is evidence that red feathers, with psittacofulvin, are more resistant to degradation. Bacillus licheniformis is a Gram positive spore-forming bacterial species of high biotechnological interest with numerous present and potential uses, including the production of bioactive compounds that are applied in a wide range of fields, such as aquaculture, agriculture, food, biomedicine, and pharmaceutical industries.
