Bacillus thuringiensis (Bt) ibhakitiriya regiramu-positive.Ivanhu vakasiyana-siyana.Zvinoenderana nekusiyana kweiyo flagella antigen, iyo yakasarudzika Bt inogona kukamurwa kuita 71 serotypes uye 83 subspecies.Zvimiro zvemhando dzakasiyana-siyana zvinogona kusiyana zvikuru.
Bt inogona kubudisa zvakasiyana-siyana zve intracellular kana extracellular bioactive components, zvakadai semapuroteni, nucleosides, amino polyols, etc. Bt inonyanya kuita basa rekuuraya zvipembenene zvinopesana nelepidoptera, diptera uye coleoptera, kuwedzera kune zvinopfuura 600 zvinokuvadza mu arthropods, platyphyla, nematoda uye. protozoa, uye mamwe marudzi ane insecticidal chiitiko kurwisa cancer maseru.Iyo zvakare inogadzira inodzivirira chirwere proto-bhakitiriya inoshanda zvinhu.Zvisinei, mune inopfuura hafu yeBt subspecies yose, hapana basa rakawanikwa.
Hupenyu hwakakwana hweBacillus thuringiensis hunosanganisira kuchinjika kwemasero ezvinomera uye spore.Mushure mekuita, kumera uye kubuda muspore yakarara, huwandu hwesero hunowedzera nekukurumidza, kuumba masero ezvinomera, uye zvino kuparadzira munzira yekuparadzanisa mabhinari.Kana sero rapatsanurwa kekupedzisira, kuumbwa kwespore kunotanga zvakare nekukurumidza.
