Bacillus - Wikipedia, the free encyclopedia thuringiensis, is an important insect pathogen, and is sometimes used to control insect pests. An easy way to isolate Bacillus is by placing non-sterile soil in a test tube with water, shaking, placing in melted mannitol salts agar, and incubating at room temperature for at least a day. The word "bacillus" is also used to describe any rod-shaped bacterium, and in this sense, bacilli are found in many different groups of bacteria. en.wikipedia.org /wiki/Bacillus   (269 words)

Bacillus thuringiensis - Wikipedia, the free encyclopedia Bacillus thuringiensis is a bacterium that lives in the soil, in the caterpillars of some moths and butterflies and also on the surface of plants. thuringiensis produces crystals of toxin that are lethal to larval stages (caterpillars) of the insects which belong to orders Coleoptera, Lepidoptera and Diptera, but are considered harmless to most other organisms, including humans. Therefore, the spores of the bacterium and the toxic crystals (that are produced in the bacterial plasmids) are used in crop protection, especially in organic farming, where the use of chemical pesticides is not considered an option. en.wikipedia.org /wiki/Bacillus_thuringiensis   (332 words)

Bacillus Thuringiensis Bacillus thuringiensis is a soil bacteria and poorly adapts to leaves or other surfaces exposed to sunlight, particularly ultraviolet light. Bacillus thuringiensis (or Bt) is a naturally occurring bacteria, common in soils. Because of this property, Bacillus thuringiensis was developed as a type of microbial insecticide, used for control of a variety of insects. cecalaveras.ucdavis.edu /bt.htm   (1073 words)

Bacillus thuringiensis Bacillus thuringiensis (known as 'Bt') is an insecticidal bacterium, marketed worldwide for control of many important plant pests - mainly caterpillars of the Lepidoptera (butterflies and moths) but also for control of mosquito larvae, and simuliid blackflies that vector river blindness in Africa. Bacillus thuringiensis is considered safe to humans and non-target species, such as wildlife. Spraying or dusting plants with spores of this bacterium appear to be environmentally safe ways to attack such pests as the gypsy moth, the tent caterpillar, and the tobacco hornworm (which also attacks tomatoes). www.magma.ca /~scimat/B_thurin.htm   (259 words)

Bacillus Bacillus antibiotics share a full range of antimicrobial activity: bacitracin, pumulin, laterosporin, gramicidin and tyrocidin are effective against Gram-positive bacteria; colistin and polymyxin are anti-Gram-negative; difficidin is broad spectrum; and mycobacillin and zwittermicin are anti-fungal. Bacillus is distinguished from the other endospore-forming bacteria on the basis of being a strict or facultative aerobe, rod-shaped, and (usually) catalase-positive. The vegetative cell surface is a laminated structure that consists of a capsule, a proteinaceous surface layer (S-layer), several layers of peptidoglycan sheeting, and the proteins on the outer surface of the plasma membrane. textbookofbacteriology.net /Bacillus.html   (5350 words)
