Antimicrobial Activity of Simulated Solar Disinfection against Bacterial, Fungal, and Protozoan Pathogens and Its Enhancement by Riboflavin

摘要

Riboflavin significantly enhanced the efficacy of simulated solar disinfection (SODIS) at 150 watts per square meter (W m~(?2)) against a variety of microorganisms, including Escherichia coli , Fusarium solani , Candida albicans , and Acanthamoeba polyphaga trophozoites (>3 to 4 log_(10) after 2 to 6 h; P < 0.001). With A. polyphaga cysts, the kill (3.5 log_(10) after 6 h) was obtained only in the presence of riboflavin and 250 W m~(?2) irradiance.
