Abstract:
The effects of hydrogen peroxides(H2O2) and hydroxyl radicals(.OH) on the purified parasporal crystals from Bacillus thuringiensis var. Kurstaki HD-1 were studied by SDS-PAGE and bioassay. The results showed that to some extent H2O2 and .OH produced a direct and deleterious effect. Hydroxyl radicals from the system Fe(II)-EDTA-H2O2 indicated more serious damage than hydrogen peroxides. There was a 44.5% loss in activity against 12-h-old larvae of Heliothis armigera when parasporal crystals were treated with 0.3% H2O2 only. However, 85.2% activity lost when parasporal crystals were treated with 0.3% H2O2 in the presence of iron(II) and EDTA.
