A1 Pockett, Hazel V.YR 1975 T1 An Insect Toxin from Spores of Bacillus thuringiensis and Bacillus cereus JF Microbiology, VO 87 IS 2 SP 359 OP 369 DO https://doi.org/10.1099/00221287-87-2-359 PB Microbiology Society, SN 1465-2080, AB SUMMARY: Spores of Bacillus thuringiensis contain a toxin active against lepidopterous larvae. This toxin can be solubilized extraction with reagents which dissolve the protein crystal of B. thuringiensis. It is inactivated crystal-specific antiserum. Spores of Bacillus cereus contain a similar toxin although the specific activity is much lower than the spores of B. thuringiensis. The B. cereus toxin contains a single major polypeptide component. Toxic activity can be solubilized from spores of both species incubation with gut juices from Pieris brassicae. , UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-87-2-359
