  • Bacillus thuringiensis  is a Gram-positive, soil-dwelling bacterium, commonly used as a biological alternative to a pesticide; alternatively, the Cry toxin may be extracted and used as a pesticide.
  • B. thuringiensis was first discovered in 1902 by Japanese biologist Shigetane Ishiwatari. In 1911, B. thuringiensis was rediscovered in Germany by
    Ernst Berliner, who isolated it as the cause of a disease called Schlaffsucht in flour moth caterpillars.
  • Bacillus thuringiensis  is a naturally-occurring soil bacterium that produces poisons which cause disease in insects.
  • Bt toxins are considered environmentally friendly by many farmers and may be a potential alternative to broad spectrum insecticides.Large-scale applications of B.t. can have far reaching ecological impacts.
  • Bacillus thuringiensis products available in the United States are comprised of one of five varieties
  • Each of the more than 800 strains of Bacillus thuringiensis may exhibit different toxicity to insects, rodents and humans. An aeration strategy was proposed for foam control in an airlift reactor with double wire mesh draft tubes. The airlift reactor was employed in the cultivation of Bacillus thuringiensis for thuringiensin production.
  • A two-step procedure was used to place a cryIC crystal protein gene from Bacillus thuringiensis subsp. aizawai into the chromosomes of two B. thuringiensis subsp. kurstaki strains containing multiple crystal protein genes.
  • The production of the bioinsecticide can be done using the aerobic cultivation.
  • The preparations of spores and crystals of Bacillus thuringiensis have been used for about 60 years for the control of insects harmful to the cultivated plants and forests and, also, for the control of insect vectors of diseases.
  • The local production of Bt biopesticides using strains isolated in the Laboratory and showing originalities, for the development of local biopesticides  industries and biofarming promotion.
  • Detailed techno-economic analysis of alternative growth substrates, namely, raw wastewater sludge; hydrolyzed wastewater sludge; starch industry wastewater for Bacillus thuringiensis var. kurstaki HD-1 (Bt) biopesticides production in comparison with semi-synthetic commercial soyameal medium was carried out.
  • To develop a cost-effective process for the production of Bacillus thuringiensis based insecticide, it is important to cultivate the bacterial strain in rich medium to obtain the highest yields of spore-crystal complexes.
  • We optimized the PCR method to detect genetically engineered Bacillus thuringiensis (Bt) maize in open quarantine fields in Kenya.
  • In the Effects of Protoplast Fusion on δ-endotoxin Production in Bacillus thuringiensis Spp. (H14) mutant forms of Bacillus thuringiensis spp. israelensis (H14) were produced.
  • Three Bacillus thuringiensis isolates designated 1M, K10-2 and V24-M with varying levels of toxicity to Chilo partellus (spotted stalk borer) were characterized to establish the basis for the differential toxicity and to identify any unique properties that may be used to screen other isolates.
  • Transgenic technology, involving a wide range of pesticidal genes from the bacterium Bacillus thuringinesis (Bt), dominates the scenario of agricultural biotechnology.   At the same time, Bt technology is also the most focused target of vehement anti-tech activism.  
  • The development of the production and use of Bacillus thuringiensis in Brazil at a commercial scale faces
    certain difficulties, among them the establishment of efficient methodologies for the quantitation of toxic products to be commercialized.
  • The recently sequenced 218 kb genome of morphologically atypical Bacillus thuringiensis phage 0305φ8-36 exhibited only limited detectable homology to known bacteriophages. The only known relative of this phage is a string of phage-like genes called BtI1 in the chromosome of B. thuringiensis israelensis.
