what are the uses of Bacillus thuringensis?
371001
Use in pest control\nB. thuringiensis produces crystals of toxin (Bt 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. This is done by spraying plants with the bacterium itself, or with an insecticide that contains the bacterial spores. The agent has been available since 1938 in France, 1950 in the USA, and was improved in the 1960s. Today different subspecies are used against the different insects, For instance, Bacillus thuringiensis israelensis is effective against mosquito larvae and some midges. Other variants used are B. thuringiensis kurstaki, B. thuringiensis aizawa, B. thuringiensis san diego, and B. thuringiensis tenebrionis.\nAnother way to protect plants is to create transgenic plants that express the gene for the bacterial toxin, as is currently done in the USA, India, China and Australia for cotton (Bt-cotton), and for corn (Bt-corn) in the U.S. and Canada. This has generated some controversy, especially regarding the ill effects Bt corn was purported to have on monarch butterflies. The emergence of resistance in affected insects is another significant issue.[2]\n\nalso see:

*Nicotine sulfate was extracted from tobacco leaves for use as an insecticide.\n*Pyrethrum which is derived from crysanthemums.\n*Rotenone which is derived from the roots of tropical legumes.\n*Azardirectin is extracted from tropical plant Azardirecta indica.\n*Microbial pesticides consist of a microorganism (e.g., a bacterium, fungus, virus or protozoan) as the active ingredient. Microbial pesticides can control many different kinds of pests, although each separate active ingredient is relatively specific for its target pest[s]. For example, there are fungi that control certain weeds, and other fungi that kill specific insects.The most widely used microbial pesticides are subspecies and strains of Bacillus thuringiensis, or Bt. Each strain of this bacterium produces a different mix of proteins, and specifically kills one or a few related species of insect larvae. While some Bt's control moth larvae found on plants, other Bt's are specific for larvae of flies and mosquitoes. The target insect species are determined by whether the particular Bt produces a protein that can bind to a larval gut receptor, thereby causing the insect larvae to starve.\n*Biochemical pesticides are naturally occurring substances that control pests by non-toxic mechanisms. Conventional pesticides, by contrast, are generally synthetic materials that directly kill or inactivate the pest. Biochemical pesticides include substances, such as insect sex pheromones, that interfere with mating, as well as various scented plant extracts that attract insect pests to traps. Because it is sometimes difficult to determine whether a substance meets the criteria for classification as a biochemical pesticide, EPA has established a special committee to make such decisions.\n*Plant-Incorporated-Protectants (PIPs) are pesticidal substances that plants produce from genetic material that has been added to the plant. For example, scientists can take the gene for the Bt pesticidal protein, and introduce the gene into the plant's own genetic material. Then the plant, instead of the Bt bacterium, manufactures the substance that destroys the pest. The protein and its genetic material, but not the plant itself, are regulated by EPA.

It's not typically used anymore. The bacteria as become resistant to it. They use a stronger antibiotic now.

Potassium - Nutritionists use this along with other vitamins and minerals to restore electrolyte balance in anorexic and bulimic patients.  (Just one example)\n\nPotassium chloride - Used by executioners who administer the death penalty by lethal injection.  A massive dose of this stops the heart.\n\nPotassium bicarbonate - Used to retard or put out oil well fires.\n\nPotassium hydroxide - Used as an ingredient in soap by soap manufacturers.\n\nPotassium nitrate - Used in the manufacture of fertilizer, matches (along with sulphur), and pyrotechnics.

Microbiologists are hunting all over the world for bacteria with amazing abilities.  ( I recently answered a question about the discovery of bacteria that extract gold from seawater).\n\nChances are, your household already contains the products of bacteria.  The enzymes in detergent, yogurt, buttermilk, and vitamin supplements and many products are produced by bacteria or fungi.\n\nBelow are two links to some current uses of microbes.\n\nI have no doubt that scientists could use bacteria to produce energy from waste.  In fact methane (natural gas) is  a fuel that can already be produced by microbial decomposition.

Step on them. Or use professional roach baits, pesticide dusts, aerosols or residual spray concentrates.\n\nCypermethrin insecticides are the most popular for killing German cockroaches.  Mop Up can also be used when mopping kitchen floors and is used primarily in restaurant roach control.  \n\nThe best professional bait for German roaches is Maxforce Gel.

Yogurt and cheese - Lactobacillus is the bacteria that is used for these.\n\nBread, wine/beer - Fungi in the form of yeast are used for these.\n\nYeast feeds off the sugars that are around and generate carbon dioxide which creates the bubbles that helps bread rise. It ferments the sugars to help make wine and beer.\n\nBacteria is helped used to process certain foods to alter the way they are - like from milk to yogurt or cheese. The presence of this bacteria helps prevent other bacteria from forming, thus helping to preserve milk by making cheese for example.

I've never heard of any attempt of last-gasp reproduction in the animal domain. I have however heard of something similar in the bacterial domain of life. Bacteria of the genus Bacillus will sporulate under the appropriate environmental cues. These cues are usually things like low amounts of water, food, extreme shifts in temerature, etc. All these cues are ones that would probably end up in the death of the organism. The spores that are created are resistant to these harsh conditions and allow the bacteria to survive for long periods of time and can germinate if conditions return to a friendlier state.

They provide excellent hard surface cleaning prior to decontamination and efficient sanitizing for bacteria on environmental surfaces. They do not contribute to indoor air pollution and they also possess excellent health and safety profiles in comparison with other commonly used germicides. Moreover, lack of toxic residues should ensure their environmental safety. As they have already been demonstrated to possess broad-spectrum activity against a variety of microorganisms in contact times relevant to field situations

You can also perform classical staining according to Gram, B. subtilis is G+ rod, than you inoculate meat-extract agar plate, incubate it for several days and old culture you can check for endospores microscopically after staining according to Wirtz and Couhlin. Spores are typically located.\nSome experiences are needed to identificate Bacilli this way.

Well, apparently, they grow quite well on certain caterpillars ...\n\n:-P\n\n... but, seriously, AFAIK the bacterium is not too fussy, or (as we microbiologists generally call it) "fastidious" about its growth requirements.  I assume it will grow on any "minimal" medium, that is, maybe a bit of Yeast Exatract, + / or tryptone or meat extract, with or without addition of agar.  You did not say whether you wanted a liquid or solid growth medium.\n\nWe find Bacillus species as reasonably - common contaminants from the environment.  Our media are designed to isolate bacteria important to human health, so they are more nutritious than Bacillus thuringiensis would need (AFAIK).\n\nIf you do grow it, be careful with it; many members of this genus produce toxins.  I suspect that Bt toxin might not be very good for humans, too.  IMO, it is probably unwise to try to grow bacteria, unless you have appropriate training and laboratory equipment.  For example, you need to sterilise media and equipment, and properly dispose of wastes, in a safe fashion, and according to local bylaws etc.\n\nI am a microbiologist.

Agricultural Applications - radioactive tracers\n\n\nRadioisotopes can be used to help understand chemical and biological processes in plants. This is true for two reasons: 1)radioisotopes are chemically identical with other isotopes of the same element and will be substituted in chemical reactions and 2)radioactive forms of the element can be easily detected with a Geiger counter or other such device.\nExample:\nA solution of phosphate, containing radioactive phosphorus-32, is injected into the root system of a plant. Since phosphorus-32 behaves indentically to that of phosphorus-31, the more common and non-radioactive form of the element, it is used by the plant in the same way. A Geiger counter is then used to detect the movement of the radioactive phosphorus-32 throughout the plant. This information helps scientists understand the detailed mechanism of how plants utilized phosphorus to grow and reproduce.
