Robison, Gable Moffitt, Neal Thomson, and Marissa Cohen, Brigham Young University, Provo, UT), Figure 20: Bacillus thuringiensis morphology (Enlarged view). Because it is capable of forming endospores that can be easily disseminated, B. licheniformis can be isolated from a variety of places, though it is mainly associated with plant materials. [5][6] It was initially named Clostridium licheniforme by H. Weigmann[7] and renamed Bacillus licheniformis by Frederick D. The isolated colonies were counted and the number of bacteria expressed as Log of Colony Forming Unit (CFU)/g of CSS. Its optimal temperature for enzyme secretion is 37C. Previous studies had found that B. licheniformis could produce a variety of biologically active substances, such as digestive enzymes, lysozyme, bacteriocin, and antibacterial peptides, which promote animal performance by improving feed digestibility, stimulating the development of immune system, enhancing intestinal mucosal barrier function, Batch experiments were evaluated to determine the maximum specific growth rate, saturation constant, inhibition constant .

I realize that the strains causing these problems were wild strains, not strains studied to be probiotics. You can see Bacillus subtilis listed on the label of many probiotics, too. 4. microbial colonies that showed mucus morphology were streaked on TSA plates to obtain pure cultures. Feathers contain high amounts of non-digestible proteins, but researchers hope that, through fermentation with B. licheniformis, they can use waste feathers to produce cheap and nutritious feather meal to feed livestock. The sample was obtained from a floor swab and incubated at 37C for 48 hours. Under good conditions, the spores will germinate and produce vegetative cells. Notice that the agar is depressed or pitted by the growth of the bacteria. 39. Pseudomonas aeruginosa cultivated on trypticase soy agar.
