Antimicrobial activity of simulated solar disinfection against bacterial, fungal, and protozoan pathogens and its enhancement by riboflavin

Abstract

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 log10 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. Copyright © 2010, American Society for Microbiology.
