SASP (small, acid-soluble spore proteins) and spore properties in Bacillus thuringiensis israelensis and Bacillus sphaericus

Entomopathogenic bacilli B. thuringiensis israelensis (Bti) and B. sphaericus (Bf) exhibit low survival on field application. It was previously shown that their spores are very sensitive to different stress effectors (heat, UV light) and especially to osmotic variations. Since SASP (Small, Acid-Solu...
