Jan 1, 2016 · The present study aims to isolate and characterize Bacillus thuringiensis (Bt) strains isolated from different sources. These strains were subjected to morphological and biochemical...

Bacillus thuringiensis is a gram-positive bacterium. The morphology of the Bacillus thuringiensis was confirmed by the microscopic test and the genius was found by the biochemical test.

The organism was named Bacillus thuringiensis by Berliner in 1911, who isolated it from a diseased flour moth larva. In 1954, Angus demonstrated that the crystalline protein inclusions …

Apr 1, 2025 · For this reason, this study introduces two test (conductivity and pH) and other methodologies previously used (bioassays, spore viability, SDS-PAGE) for determining the …

Dec 4, 2022 · Here, to develop tools for the detection and the discrimination of Bt in food, we carried out a genome-wide association study (GWAS) on 286 complete genomes of Bc group …

Jul 5, 2022 · Common important tests include Sodium acetate selection test, Gram’s staining, Amino black and Ziehl’s carbol fuchsin staining, Endospore staining, Catalase test, checking …

Field tests were conducted in 1980, 1981, and 1982 with a new Bacillus thuringiensis formula called Futura. Tests were conducted with a Grumman AgCat aircraft on 40 ha forest blocks …

In the present study, four new strains i.e. 1953, 6941, 4714 and 4715 of Bacillus thuringiensis have been taken and characterized using morphological studies, growth curve analysis, …

Biochemical characterization The isolate was subjected to various biochemical tests viz., catalase, starch hydrolysis, casein hydrolysis, nitrate reduction, voges- proskauer reaction, oxidase test, …

The efficiency of a novel biomarker (the transcriptional regulator, XRE) was tested and evaluated in differentiating Bacillus thuringiensis from Bacillus cereus group species in environmental …
