Bacillus Thuringiensis - an overview ScienceDirect Topics
WebBacillus thuringiensis ( Bt) is a group of strains or isolates of naturally occurring soil bacteria which mainly exerts toxicity through the production of Crystal (Cry) toxins. Cry toxins are used worldwide as aerial sprays or in transgenic plants to control disease-vector insect and crop pest populations. Different strains of Bt have specific ... WebApr 4, 2009 · We manipulated spore density in two experiments, without altering the initial toxin content, by combining Btk rif R with a near-isogenic mutant that fails to produce crystal endotoxins (Btk rif R Cry-). This mutant was isolated after three transfers of LB broth culture of Btk rif R grown at 37°C and inspection of crystal production via microscopy.
