Binding of the protoxin and toxin proteins ofBacillus thuringiensis subsp.kurstaki on clay minerals


The equilibrium adsorption and binding of the delta-endotoxin proteins, i.e., the protoxins (Mr=132 kDa) and toxins (Mr=66 kDa), fromBacillus thuringiensis subsp.kurstaki were greater on montmorillonite than on kaolinite (five-fold more protoxin and three-fold more toxin were adsorbed on montmorillonite). Approximately two- to three-fold more toxin than… (More)
