More than 200 Bacillus species exist; most do not cause disease. 16. It also exhibits some hemolytic activity and is salt tolerant. 13. 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. FIG. Researchers culture and isolate this protease to add it into detergents. Independent.ie. Ecologists are studying the effects of B. licheniformis on bird feathers. Color ranges from opaque to white. FIG. FIG. [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. 2004;5(10):R77. Septicaemia is blood poisoning, and is classified as having a large amount of bacteria in the blood. The image below shows how Gram-positive bacteria have a much thicker peptidoglycan layer (in purple). 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. Determinative Bacteriology, Eight Edition, The Williams & Wilkins Company, Baltimore. 6. 27. Irregular form, lobate margin.

A colony is defined as a visible mass of microorganisms all originating from a single mother cell, therefore a colony constitutes a clone of bacteria all genetically alike. The iso-lated microorganisms from sh samples were stored in Also, cultures of B. licheniformis are made to retain its protease, which is in turn used in laundry detergent. B. subtilis is most commonly singular in arrangement. (3) Poovendran, P., Kalaigandhi, V., KamalaseKanan, V., Jamuna rani, E., Poongunran, E. A study of feather keratin degradation by Bacillus licheniformis and quantification of keratinase enzyme produced.Journal of Microbiology and Biotechnology Research. Based on colony morphology, microscopic observations, and cultural, biochemical, and physiological properties, the bacterium was given the name Bacillus spp., Alcaligenes spp., Erwinia spp., Serratia spp., or Pseudomonas spp. Yao K. 2014. 2004;5(10):R77. This reaction also occurs in Gram-negative bacteria; however, the significantly lower levels of peptidoglycan mean that cell samples do not remain purple when a pink counter-stain (safranin) is added. W.B. Growth temperature from 15 C to 50-55 C. It is also often found on feathers of ground-dwelling and aquatic species of birds. 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].

[19][20] B. licheniformis has been found to be the causative agent of ventriculitis, ophthalmitis, bacteremia, peritonitis, and endocarditis. [2] Subtilisin Carlsberg (P00780) secreted by B. licheniformis is used as a detergent protease. There is also research about the possibility that B. licheniformis causes changes in color in birds' feathers; this will provide information on the evolution of molting. It is a rod shaped, endospore bearing bacteria and belong to the family Firmicutes. FIG. A pathway that leads to endospore formation is initiated when the bacterium is starved. 25. 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. Buiuc D., Negut M. , 1999. Since it can grow in alkaline conditions, it produces a protease that can survive at high pH levels. Its optimal growth temperature is around 50C, though it can survive at much higher temperatures. The rod shape also helps bacteria glide or move through watery environments and provides regular building block shapes that make biofilm formation easier. 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. Its optimal temperature for enzyme secretion is 37C. Ohmic heating has potential uses such as blanching, evaporation and pasteurization of food; it is a high temperature, short time, and a purely bulk heating method. 54. The ability of B. subtilis to produce bacteriocins peptides that possess antimicrobial activity make it a potential treatment against bacterial infection. the colony characteristics under light microscope Bacillus aryabhattai strain B8W22 16S ribosomal RNA gene, partial . 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.

These bacteria are commonly known to cause food poisoning and food spoilage. one double-stranded DNA molecule contained within a circular chromosome. It has a variety of uses including commercial processes. The future may provide a microplastics solution in the form of specific bacterial combinations where, in the same way as we combine cytotoxic drugs to fight specific forms of cancer, plastic-digesting combinations can be used to degrade different types of polyethylene. Macrophages are central cells in the immune response . A white base of hyphae surrounds green and yellow grainy spore formation in the center of the colony.

Without the support of synthetic chemicals, B. subtilis is not the fastest strain it reduces dry-weight plastic by around 1.75% over a term of 30 days. Under good conditions, the spores will germinate and produce vegetative cells. A taxonomical approach shows that it is closely related to B. subtilis (Lapidus et al., 2002; Xu and Cte, 2003; Rey et al., 2004). Figure 1: Serratia marcescens morphology (Enlarged view). Colonies are both round and irregular in shape, with irregular (undulate, fimbriate) margins. FIG. The genera Bacillus and Clostridium constitute the family Bacillaceae.

Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques. 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. FIG.

Bacillus subtilis PspoIIA-gfp viewed at low magnification. There is current research on B. licheniformis (strain SB3086) and its effects as a microbial fungicide. Sibakov M, Palva I: Eur J Biochem: 10.1111/j.1432-1033.1984.tb08594.x: 1984 * Metabolism This text tells us that up to 5% of the B. subtilis genome is dedicated to the production of antimicrobial compounds (AMCs). Non-typical Bacillus strains may be very small and spore formation often fails to occur. The bacterium is also used in the health and catering industries, especially when testing how clean certain work surfaces and materials are. Recently, Singh et al. In this study, four strains were already isolated and selected previously (D1, D2, X1, and X2) with high probiotic potential. 55. Whole-genome sequencing and phenotypic testing of 104 strains of Bacillus licheniformis and Bacillus paralicheniformis from a variety of sources and time periods was used to characterize the genetic background and evolution of (putative) antimicrobial resistance mechanisms. As mentioned, Bacillus licheniformis is commonly found on bird feathers; by fermentation with B. licheniformis, the large amounts of non-digestible proteins found in the feathers can turn into a feather meal for livestock. 38.

Unknown isolate cultivated on trypticase soy agar. The majority of isolates fell into the Bacillus Bergey's Group A together with Bacillus subtilis and Bacillus licheniformis. B. subtilis uses encompass research and partially-proven inclusion in dietary supplements. B. licheniformis has proved itself as a multipurpose organism and has gained popularity along with B. subtilis. In addition to the oxidative degradation of zearalenone (ZEN) and aflatoxin B1 (AFB1), CotA laccase also has the ability to degrade the Alternaria toxin alternariol (AOH).
