Characterization, direct sequencing of the PCR amplicon and phylogenetic relationship was done to discover a novel Vip protein genes of the Bt isolates, to improve the prospects for insect control, more Vip proteins should be sought out and researched to predict their insecticidal activity. Characterization was based on direct sequencing of PCR amplicon(More)
The Western Ghats of Karnataka natural ecosystem are among the most diverse and is one of the eight hottest hotspots of biological diversity in the world, that runs along the western part of India through four states including Karnataka. Bacillus thuringiensis (Bt) strains were isolated from soils of Western Ghats of Karnataka and characterized by molecular(More)
Bacillus thuringiensis (Bt) strains were isolated from soil samples of Great Nicobar Islands, one of the “hottest biodiversity hotspots,” where no collection has been characterized previously. The 36 new Bt isolates were obtained from 153 samples analyzed by crystal protein production with light/phase-contrast microscopy, determination of cry gene profile(More)
Applications to combat non-lepidopteran insects are not as common as applications against lepidopteran insects. The aim of the present work was to isolate and identify Bacillus thuringiensis isolates from soil samples using five approaches, viz., analysis of crystal protein production by microscopy; detection of cry gene content by PCR, SDS-PAGE profiling;(More)
Three-dimensional (3D) models for the 79.2 kDa activated Cry1Ib9 and 77.4 kDa activated Cry3A δ-endotoxins from Bacillus thuringiensis (Bt) native isolates that are specifically toxic to Coleopteran insect pests were constructed by utilizing homology modeling online tool. Evidences presented here, based on the identification of structural equivalent(More)
— In Hazardous environment industries where the emission of toxic gases and effluents will have an impact on the health of the operators, the recording of health parameters of individual operators is very important. In such situation the health monitoring of operators are being monitored and processed centrally by a server and this can be powered by a(More)
