(5), Bacillus licheniformis is a spore-forming soil organism that contributes to nutrient cycling and has antifungal activity. Information on morphological and physiological properties Morphology [Ref. I realize that the strains causing these problems were wild strains, not strains studied to be probiotics. There are increased concerns regarding microbial contaminations, from such bacteria as E. coli and B. licheniformis, when it comes to food processing. The initial sample was obtained from a swab taken from the bottom of a shoe and incubated at 37 C for 48 hours. 3. Bacillus licheniformis was found to be the only isolate in 3 cases of bovine abortion. Scientists are currently exploring its ability to degrade feathers for agricultural purposes. The compound 2-phenylethanol (2-PE) is a bulk flavor and fragrance with a rose-like aroma that can be produced by microbial cell factories, but its cellular toxicity inhibits cellular growth and limits strain performance. New York, Nova Science Publishers. Keratinolytic activities of B. licheniformis could aid in converting this by-product into a useful protein source for animal feed. Cooked meats, raw milk, vegetables, and processed baby foods are also at risk. ABIS Encyclopedia [6][9] B. licheniformis is found in a wide variety of environments, but especially in soil and in the feathers of birds, where B. licheniformis degrades -keratin. supplementation on the apparent ileal This gives researchers a lot of material to work with in the race to produce a bacteriocide that pathogenic bacteria do not become resistant to.

(9). Food poisoning can cause cramping, nausea, vomiting, and diarrhea, and fatalities by B. licheniformis toxins, though rare, have been reported. Endospores allow the organism to survive in a variety of harsh environments (high salt concentrations, for example) until conditions are more favorable, when it returns to a vegetative state. Eight strains each of Bacillus subtilis, Bacillus pumilus, Bacillus licheniformis, and Bacillus amyloliquefaciens were analyzed by using pyrolysis gas-liquid chromatography.

Bacitracin is composed of a mixture of the cyclic polypeptides that B. licheniformis produces; ironically the purpose of Bacitracin is to inhibit the growth of B. licheniformis. However, the most interesting of this bacterias potential uses is as an antimicrobial drug alternative. As with the shape, bacteria colony is usually fairly circular. 1999 October; 65(10): 46374645. Its optimal growth temperature is around 50C, though it can survive at much higher temperatures.

Bacillus species can be either obligate aerobes which are dependent on oxygen, or facultative . B. subtilis is most commonly singular in arrangement. 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 ). Bacillus cereus is an aerobic spore-forming bacterium that is commonly found in soil, on vegetables, and in many raw and processed foods. Lab tests have confirmed the enzyme's ability to break up and remove bacteria present in plaque, and thus prevent the build up of plaque.
