Outline of Final Research Achievements

This study aims the assessment and disinfection of airborne microorganisms in postharvest facilities. In the first, concentrations of airborne particles and the populations of airborne microorganisms in a postharvest facility were assessed and evaluated. Next, we found that the electrostatic precipitator could collect microorganisms in the air under various relative humidity. It was also found that the photocatalyst solution under UV-A irradiation decreased the microbial populations in the solution to uncountable levels. Finally, the collection and disinfection of airborne microorganisms in postharvest facilities was indicated as possible, by application of above methods.
