Optimization of medium composition for the production of mosquitocidal toxins from Bacillus thuringiensis subsp. israelensis.
Optimization of chicken feather (CF) based culture medium for the production of Bacillus thuringiensis subsp. israelensis (Bti) biomass in combination with the agro industrial by-product (coconut cake, CC) and manganese chloride (MnCl2) has been evaluated. The biomass yield of Bti spore/crystal toxin was highest (12.06 g/L) from the test medium (CF+CC+MnCl2) compared to the reference medium (Lu...
متن کاملMedium for the production of primary powder of Bacillus thuringiensis subsp. israelensis.
Five media, formulated from the seeds of five legume varieties, dried cow blood, and mineral salts, were assessed for the growth and production of insecticidal properties of Bacillus thuringiensis subsp. israelensis. Bacterial powders prepared from the broth cultures were assayed against the larvae of Aedes aegypti, Culex quinquefasciatus, and Anopheles gambiae. A standard primary powder of B. ...
متن کاملEvaluation of a new formulation of Bacillus thuringiensis israelensis.
The aim of this study was to determine the potency (ITU) and efficacy of a liquid formulation of Bacillus thuringiensis israelensis developed by the State University of Londrina named BioUel, against early fourth instar larvae of Aedes aegypti and Culex quinquefasciatus. The ITU/mg of BioUel was 960, the LC₅₀ was of 0.271 (± 0.39) ppm, and the LC₉₅ was 0.634 (± 0.099) ppm, in larvae of C. quinq...
متن کاملAntibacterial activity of Cyt1Aa from Bacillus thuringiensis subsp. israelensis.
Cyt1Aa is a delta-endotoxin protein that is produced by Bacillus thuringiensis subsp. israelensis. It is a membrane pore-forming toxin that is lethal to insect larvae and is broadly cytolytic to vertebrate as well as invertebrate cells. Cyt1Aa is produced as a protoxin of 27 kDa. Proteolytic activation results in a reduction of the molecular mass to approximately 23-24 kDa and a threefold incre...
متن کاملOral toxicity of Bacillus thuringiensis subsp. israelensis to adult mosquitoes.
The solubilized entomotoxin of Bacillus thuringiensis subsp. israelensis killed adult male and female mosquitoes of several genera and of various physiological states when it was administered orally. Adult mosquito mortality was further influenced when the preparation was contained in sucrose solution. The potential implication for the control of adult mosquitoes is discussed.
