Sources/Uses

Bacillus thuringiensis strains of bacteria produce delta-endotoxins that are used to control various types of insects; Some isolates also produce thuringiensin, a beta-exotoxin that has to be removed from insecticide production batches; [Reference #1] "Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, commonly used as a biological pesticide; . . . During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called δ-endotoxins, that have Insecticide action. This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes. Many crystal-producing Bt strains, though, do not have insecticidal properties."
