I-Bacillus thuringiensis (Bt) igciwane le-gram-positive.Kungabantu abahlukahlukene.Ngokomehluko we-antigen yayo ye-flagella, i-Bt ehlukanisiwe ingahlukaniswa ngama-serotypes angu-71 kanye nama-subspecies angu-83.Izimpawu zezinhlobo ezahlukene zingahluka kakhulu.
I-Bt ingakhiqiza izinhlobonhlobo zezingxenye ze-intracellular noma ze-extracellular bioactive, njengamaprotheni, ama-nucleosides, ama-amino polyols, njll. I-Bt ikakhulukazi inomsebenzi wokubulala izinambuzane ngokumelene ne-lepidoptera, i-diptera ne-coleoptera, ngaphezu kwezinhlobo ezingaphezu kuka-600 eziyingozi kuma-arthropods, i-platyphyla, i-nematoda kanye i-protozoa, nezinye izinhlobo zinomsebenzi wokubulala izinambuzane ngokumelene namaseli omdlavuza.Iphinde ikhiqize izinto ezisebenzayo ze-proto-bacterial ezimelana nezifo.Kodwa-ke, ngaphezu kwengxenye yazo zonke izinhlobo ze-Bt, awukho umsebenzi otholiwe.
Umjikelezo wempilo ophelele we-Bacillus thuringiensis uhlanganisa ukwakheka okushintshanayo kwamangqamuzana ezitshalo nezinhlamvu.Ngemva kokusebenza, ukuhluma nokuphuma ku-spore ethule, umthamo weseli ukhula ngokushesha, wakhe amangqamuzana e-vegetative, bese usakaza ngendlela yokuhlukaniswa kanambambili.Lapho ingqamuzana selihlukene okokugcina, ukwakheka kwezinhlamvu kuqala futhi ngokushesha.
