Bacillus licheniformis is a hardy probiotic which is commonly combined with other Bacillus bacteria for optimal probiotic effects. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 16: Streptomyces albus morphology (Enlarged view). This is because when under stress, these bacteria (including B. subtilis ) transform into spores and become dormant. Currently there are many electrical techniques for food processing, one such example is Ohmic heating. This rigidity helps to maintain the rod shape of the cell and can withstand high intracellular pressure. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 29: Unknown isolate morphology (Enlarged view). Shape A bacterial colony can manifest in various shapes which include but not limited to the following: Spiral Bacteria that are twisted or helical in shape which looks like little corkscrews. 32. 1. FIG. FIG. Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques. FIG. Statistical analysis with canonical variates gave four well-separated groups, which represented the four species. Note the slightly umbonate, brick red colonies characteristic of this organism. Although it is most common to isolate this bacterium from is soil, it is believed that B. licheniformis can actually be isolated from practically anywhere since it produces highly resistant endospores that are spread around with dust. Note the lemon-yellow colonies characteristic of this organism. On agar media: colonies become opaque with dull to rough surface, hair-like (6)Hughes, R. C.

This sample was obtained from a floor swab and incubated at 37C. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 12: Unknown isolate morphology (Enlarged view). Bacillus licheniformis is a bacterium that is commonly found in soil and bird feathers. It causes bread spoilage, or more specifically, a condition called "ropy bread" (1). It can exist in a dormant spore form to resist harsh environments, or in a vegetative state when conditions are good. "Bacillus Subtilis. It also exhibits some hemolytic activity and is salt tolerant. Wastewater must have its pH normalized, have lower chemical oxygen demand (COD) and total suspended solids (TSS) concentrations, and be free of excess chloride. Elevation it pertains to the cross-sectional shape of the colony or side view of the colony such as: Margin It pertains to the magnified shape of the colonys edge which includes: Opacity it pertains to the characteristics of the colony such as: Image 5: Images of the bacterial colony with a varying degree of pigmentation. The colony appears mucoid under the raised rhizoid growth. Abstract. Reports about Bacillus licheniformis having detrimental effects on insect, avian, plant, and estuarine marine species are fortunately almost non-existent. Bacillus subtilis PspoIIA-gfp viewed at low magnification. Colonies have a sticky consistency when manipulated with a loop. Laboratories use B. subtilis when studying and finding new treatments for infection. Cross-links between peptide chains create a crystal-lattice like structure [6]. (Tasha Sturm, Cabrillo College, Aptos, CA), Figure 56: Close-up View of the Edges of an Unknown Bacterium on Trypticase Soy Agar. 6346. B. licheniformis can also cause food-borne gastro-enteritis, which is infection of the gut that can lead to a life threatening condition called septicaemia. The surface of B. licheniformis colonies are often rough and wrinkled, with "licheniform", or hair-like growths. | Privacy Policy, Terms of Use and State Disclosures. (Tasha Sturm and Marina Sturm, Cabrillo College, Aptos, CA), Figure 52: Unknown Fungal Isolate on Trypticase Soy Agar Exhibiting Small Round Colonies. 2004;5(10):R77. The genus Bacillus covered a great diversity of strains and some of them are strictly aerobic, while others are facultative anaerobic. (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. (D. Barrie Johnson, University of Wales, UK), Figure 32: Thiomonas-like bacteria morphology (Enlarged view). Bacillus licheniformis and Bacillus subtilis are closely related species . It is believed that this bacterium is involved in the evolution of molting and patterns of color in birds due to its feather degrading capability. Macrophages are central cells in the immune response . It is also resistant to some commonly used antibiotics, including oxacillin and nafcillin. Bacteriocins from B. subtilis include the lanthionine-containing peptide antibiotic (lantibiotic peptide) called subtilin and an antibiotic called subtilosin. Contamination with this bacterium will make the bread sticky and stringy; the ropy bread will also start to develop a strong odor after contamination. Bacillus subtilis PabrB-gfp after 14 days viewed at high magnification. ( 1974) . Volume I: Bacillus subtilis. A. and Vicente A. An arrangement might be two (diplo) bacteria, chains (strepto), or palisades (side-to-side clusters), for example. There are various types of bacteria and each type produces differently looking colonies. A pathway that leads to endospore formation is initiated when the bacterium is starved. Bacillus Subtilis. 1 IntroductionBacillus licheniformis is a Gram-positive, endospore-forming, saprophytic organism that occurs in plant and soil (Veith et al., 2004). 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 Circular form.

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]. 11. A. Bacillus licheniformis B. Bacillus megaterium C. Bacillus globigii D. Bacillus mycoides 39. Once in the gut, these spores become active and colonize. Dairy products are at increased risk of being contaminated with toxin-producing isolates of B. licheniformis. [5][6] It was initially named Clostridium licheniforme by H. Weigmann[7] and renamed Bacillus licheniformis by Frederick D. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 17: Mycobacterium smegmatis morphology (Enlarged view). Bacillus subtilis PabrB-gfp viewed at low magnification. FIG. Bacillus are a genus of Gram-positive bacteria used as probiotics for animal and human consumption. Non-pathogenic forms are often used in the biotechnology sector, including Bacillus subtilis. Streptomyces albus cultivated on nutrient agar. It is a gram-positive, mesophilic bacterium. The probiotic effects of seven newly isolated gut bacteria, from the indegenous honey bees of Saudi Arabia were investigated. Non-typical Bacillus strains may be very small and spore formation often fails to occur. The symptoms include stomach pains, (acute) diarrhea, and possible vomiting. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 46: Streak plate isolation of Mycobacterium smegmatis on trypticase soy agar. 30. Various organisms can grow on solid media. With antibiotic resistance on the increase, new therapies for bacterial infections are receiving a lot of attention.

Irregular form, lobate margin. The genera Bacillus and Clostridium constitute the family Bacillaceae. FIG. Bacillus licheniformis is a bacterium commonly found in the soil. 1999 October; 65(10): 46374645. Epub 2004 Sep 13. B. licheniformis is a motile organism capable of fermenting sugars (lactose, glucose, mannitol) and excreting useful extracellular enzymes including but not limited to: catalase, casease, urease, deaminase, protease, and lipase. (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 40: Unknown isolate morphology (Enlarged view). Three unknown isolates from this study (BLAST <95% match) and three "uncultured Bacillus" clones of isolates . The Gram stain, named after its developer Hans Christian Gram, is a method of morphologic identification. Although B. licheniformis often occurs in high numbers in these foods, it's presence is not usually regulated in contrast to B. cereus, which is credited with most food poisoning incidents by the Bacillus species. A green discoloration on blood agar may appear. (9). J. Mol. Biologydictionary.net Editors. Our website services, content, and products are for informational purposes only. The American Society for Microbiology It is spore-forming under harsh conditions and closely related to the widely studied B. subtilis. 15. Can J Microbiol 51: 191 196. 1. Bacillus licheniformis was isolated from soil of different house gardens. Serratia marcescens colonial morphology. 2006 ). TProbiotic dietary supplements are cheap to manufacture and do not require refrigeration when packaged in the form of spores. Circular form, entire margin. Bacillus licheniformis is a bacterium that is commonly found in soil and bird feathers. Colony morphology can sometimes be useful in bacterial identification. (Richard A. Robison, Gable Moffitt, Neal Thomson, and Marissa Cohen, Brigham Young University, Provo, UT) Figure 21: Unknown isolate morphology (Enlarged view). It is also often found on feathers of ground-dwelling and aquatic species of birds. A taxonomical approach shows that it is closely related to B. subtilis (Lapidus et al., 2002; Xu and Cte, 2003; Rey et al., 2004). (Bryan MacDonald, Christopher Adams, and Kyle Smith, Brigham Young University, Provo, UT), Figure 39: Lactobacillus plantarum morphology (Enlarged view). Also, cultures of B. licheniformis are made to retain its protease, which is in turn used in laundry detergent. (Richard A. Robison, Gable Moffitt, Neal Thomson, and Marissa Cohen, Brigham Young University, Provo, UT), Figure 31: Thiomonas-like bacteria morphology (Enlarged view). It is found primarily in soil and on birds that spend a majority of their time near the soil. Epub 2004 Sep 13. Streptomyces albus cultivated on nutrient agar. (Tasha Sturm and Marina Sturm, Cabrillo College, Aptos, CA), Figure 53: Unknown Organism Exhibiting Glossy Rhizoid Growth. (5), Bacillus licheniformis is a spore-forming soil organism that contributes to nutrient cycling and has antifungal activity. 38. Bacillus licheniformis was found to be the only isolate in 3 cases of bovine abortion. B. licheniformis has proved itself as a multipurpose organism and has gained popularity along with B. subtilis. The effects of temperature(30-40C), fermentation time (24-72 h), initial medium pH (6.0-9.0), carbon sources (soluble, wheat,rice and corn starches) and substrate concentration (5-30 g/L) on the .
