摘要

Dioxiranes generated in situ from pyruvates (alpha-keto esters) and Oxone have been found to be environmentally friendly oxidizing agents for disinfection. These oxidizing agents were highly effective for destruction of various strains of bacteria, fungi, and bacterial endospores in a wide temperature range with exceptional stability. Notably, by using an aqueous solution of methyl pyruvate (1a) and Oxone/ NaHCO3, complete destruction of bacteria such as Staphylococcus aureus and fungus Penicillium corylophilum was achieved within 5 min at 20 degrees C at neutral pH. Highly chemical-resistant bacterial endospores of Bacillus cereus could also be destroyed. The high antibacterial activity of la could be attributed to its strong electron-withdrawing a-ester group.
