I-Bacillus thuringiensis (Bt) yintsholongwane yegram-positive.Ngabemi abahlukeneyo.Ngokomahluko we-antigen ye-flagella, i-Bt eyedwa ingahlulwa ibe yi-71 serotypes kunye ne-83 subspecies.Iimpawu zeentlobo ezahlukeneyo zinokuhluka kakhulu.
I-Bt inokuvelisa iintlobo ezahlukeneyo ze-intracellular okanye i-extracellular bioactive components, ezifana neeprotheni, i-nucleosides, i-amino polyols, njl njl. I-Bt ikakhulu inomsebenzi we-insecticidal ngokumelene ne-lepidoptera, i-diptera kunye ne-coleoptera, ngaphezu kweentlobo ezingaphezu kwe-600 ezinobungozi kwi-arthropods, i-platyphyla, i-nematoda kunye ne-coleoptera. protozoa, kwaye ezinye iintlobo zinemisebenzi yokubulala izinambuzane ngokuchasene neeseli zomhlaza.Ikwavelisa izinto ezisebenzayo zeproto-bacterial ezinganyangekiyo.Nangona kunjalo, ngaphezu kwesiqingatha sazo zonke ii-subspecies ze-Bt, akukho msebenzi ufunyenweyo.
Umjikelo opheleleyo wobomi be-Bacillus thuringiensis uquka ukwakheka okutshintshisanayo kweeseli zezityalo kunye ne-spore.Emva kokusebenza, ukuhluma kunye nokuphuma kwi-spore eleleyo, umthamo weseli ukhula ngokukhawuleza, wenze iiseli zezityalo, kwaye emva koko usasaze ngendlela yokuhlukana kwebini.Xa iseli yahlule okokugqibela, ukumila kwembewu kuqalisa kwakhona ngokukhawuleza.
