Determining Factors of Microbial Air Quality of Pleurotus Ostreatus Cultivation Facility

Abstract

Microbial air quality is a critical determinant of environmental hygiene and production efficiency in Pleurotus ostreatus cultivation facilities, yet it remains insufficiently addressed in many commercial systems. Airborne microorganisms, including bacterial cells and fungal spores, originate from multiple sources such as growth substrates, mushroom biomass, irrigation practices, human activity, ventilation systems, and the surrounding outdoor environment. Once aerosolized, these bioaerosols are transported, deposited, or removed through dynamic indoor air processes influenced by environmental and operational conditions
