  • The delta-endotoxin from B. thuringiensis subsp. damstadienszs 73E10-2 was resistant to high concentration of salt (4M NaBr), organic solvents (50% acetone), denaturants (4 M urea), and neutral detergents (10% triton X-100). In contrast, the toxin was inactivated by treating with charged detergents as well as guanidine hydrochloride or carbon tetra-chloride. The delta-endotoxin is not a sulfhydryl activated toxin, but modification of the lysine side chains eliminated toxicity against mosquito larvae.
