the toxic protein secreted by bacillus theory genesis is
Bacillus thuringiensis During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called δ-endotoxins, that have insecticidal action. This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes, such as Bt corn.[4] Many crystal-producing Bt strains, though, do not have insecticidal properties.[5]
