Among Bacillus species, some are harmful to humans, plants or other organisms such as Bacillus cereus which can cause spoilage in canned foods, food poisoning and Bacillus anthracis cause anthrax; Bacillus typhi causes typhoid disease. Bacillus megaterium strain ATCC 14581 can be found in products available to consumers. The Government proposes that no further action under CEPA 1999 be taken on this organism in regards to potential risk to Canadians and to the environment. With a cell length of up to 4 µm and a diameter of 1.5 µm, B. megaterium is amongst the biggest known bacteria. A. Biodegradation of Azo Dye by Moderately Halotolerant. With a cell length of up to 4 µm and a diameter of 1.5 µm, B. megaterium is amongst the biggest known bacteria. Răducănescu H., Valeria Bica-Popii, 1986, Bacteriologie veterinară, Ed. The characteristics of Bacillus megaterium strain ATCC 14581 make it suitable for use in various applications, including wastewater treatment, bioremediation and biodegradation, cleaning and deodorizing, drain and septic treatment as well as enzyme and chemical production. The name B. megaterium is a nominative noun in apposition (see Rule 12 of IBCN) and is formed from the Greek adjective mega, (μέγας , μεγάλη, μέγα) meaning "great", and a second word of unclear etymology. B. megaterium grows at temperatures from 3 °C to 45 °C, with the optimum around 30 °C. It is found in soil and considered a saprophyte. ( 1974) –. Colonies are detected by their appearance and suspects should be observed microscopically for the typically large cells of this species. Bacillus Megaterium (Our second choice was Bacillus Cereus) Habitat Information. It is considered aerobic. It is considered Aerobic, but, it is also capable of growing under anaerobic conditions when necessary. ==References n. teras -atis, monster, beast; N.L. Nahid, E.-A. Bacillus megaterium, Bacillus megaterium. Bacillus megaterium is one of the first bacteria's genome that has been fully coded. Agriculture. Claus, D. Anreicherung und Direktisolierung aerober sporenbildender Bakterien. I. È uno dei più grandi eubatteri che si possono trovare nel suolo. Isolated from foods and clinical specimens. There is no conclusive evidence in the scientific literature to suggest that Bacillus megaterium strain ATCC 14581 is likely to have adverse effects on the environment. Most notably, B. megateriumis the organism that was used by Lwoff and G… Colonies are detected by their appearance and suspects should be observed microscopically for the typically large cells of this species. Bacillus megaterium is a rod-like, Gram-positive, mainly aerobic spore forming bacterium found in widely diverse habitats. Canadians may be exposed to Bacillus megaterium strain ATCC 14581 from the use of consumer or commercial products containing this strain, and to a lesser extent from environmental media. 7H2O; 12g agar; distilled water to 1 litre; adjust pH 7.0. May become yellow, Spores occur in soil, feces. Identification and Analysis of Bacillus megaterium.  However, some subsequent authors called it B. megatherium assuming the name was incorrectly spelled. Nahid, E.-A. B. megaterium has often been used in the laboratory, and is used as an industrial organism that is able to produce a variety of proteins and sources of bioremediation. Bacillus megaterium strain ATCC 14581 is a bacteria that could have a number of consumer, commercial and industrial uses. Using Bacillus megaterium scientist have developed numerous proteins that are commonly used in the medical and agricultural field. Gram positive rod, that is motile. Wilhelm Engelmann, Leipzig, 1884. adj. Considering all information presented in this assessment, the risk to human health from Bacillus megaterium strain ATCC 14581 is low. The function of the proteinaceous surface layer, made of crystalline glycoprotein subunits, is unknown. Bacillus megaterium strain ATCC 14581 is currently used in Canada for a variety of consumer, commercial and industrial applications. Medicală, Bucureşti. Phenotypic and Genetic Variability Among Three Bacillus Megatherium Isolates. Three hypotheses of the epithet "megaterium" are possible:, Consequently, it was decided in the first jouridical opinion of the Bacteriological code that the name should remain "megaterium" given the unclear meaning. La specie fu descritta nel 1884 da Anton de Bary, che lo chiamò Bacillus megaterium, ma non diede un'etimologia. Bacillus megaterium is latin for the big beast because it is an extremely large bacteria, it is about 100 times as large as E. coli. Phenotypic and Genetic Variability Among Three Bacillus Megatherium Isolates. It may be involved in bacterial metal interactions. The biotechnological study of the Bacillus megaterium provides a plethora of different proteins that they are able to employ in important medical, scientific and industrial advances. Also, considering all information presented, there is low risk of harm to organisms and the broader integrity of the environment from Bacillus megaterium strain ATCC 14581. There is no evidence in the scientific literature to suggest that Bacillus megaterium strain ATCC 14581 is likely to have adverse effects on human health. Therefore, it is concluded that Bacillus megaterium strain ATCC 14581 is not harmful to human health or to the environment. In humans, Bacillus megaterium is generally considered to be non-pathogenic, and is rarely isolated as an opportunistic pathogen in individuals with pre-existing health conditions. Il nome è un sostantivo in apposizione ed è formato dall'aggettivo greco mega (μέγας, μεγάλη, μέγα), che significa "grande", e da una seconda parola di etimologia poco chiara. Shimizu, K., Nakamura, H. & Ashiuchi, M. Salt-Inducible Bionylon Polymer from, Khan, J. We investigated the effects of temperature, pH, inoculation size, and initial quinclorac concentration on growth and degrading efficiency of Q3. However, not all strains can use nitrate, therefore the recommendation to use the ammonium ((NH4)2SO4) medium in parallel. ): Vergleichende Morphologie und Biologie der Pilze, Mycetozoen und Bacterien. A volte questo particolare batterio può essere trovato anche su superfici comuni che vengono toccate frequentemente. Plates are incubated at 30 °C. Genus species. However, in the context of experimental investigations into their biocontrol potential, some strains of Bacillus megaterium have shown pathogenic potential towards some insects and nematodes when directly inoculated with high concentrations.
