Abstract: It has been established now that insects are acquiring resistance to commercial products of Bacillus thuringiensis. So there is a continuous search for bacteria producing new toxins. With this in view, an insecticidal B. thuringiensis was isolated from soil sample obtained from the vicinity of a penicillin factory in Vadodara, India. The isolate belongs to serotype H-14. Phenotypic characters of the isolate were identical to standard B. thuringiensis var. israelensis IPS-82. It was found to possess good larvicidal activity against Anopheles stephensi and Culex pipiens and exhibited high resistance for penicillin (500 ug/ml), The electrophoretic protein profiles of purified crystals with standard B. thuringiensis (IPS-82) were studied. The isolate apparently showed the same protein profile as that of B. thuringiensis var. israelensis. Soil with natural selective pressure of antibiotic penicillin thus appears to be a good ecological niche for the isolation of B. thuringiensis.
