INFLUENCE OF ENVIRONMENTAL FACTORS ON THE GROWTH OF BUILDING DETERIORATING FUNGI: ASPERGILLUS FLAVUS AND PENICILLIUM CHRYSOGENUM
AbstractThe performance of whole building depends on many factors: structure, coating, environment, climate, type of use, service etc. Fungi are essential for the survival of our global ecology but they may pose a significant threat to the health of occupants when they grow in our buildings. The most important factor that affect microbial growth on buildings materials are temperature, moisture and nutrients. The moisture conditions connected with temperature and exposure time are the most important factor for the development of biological problems and damage in buildings. In vitro studies were conducted on the effect of temperature, pH levels and moisture on the growth of Aspergillus flavus and Penicillium chrysogenum. Maximum growth was observed on pH level 6 and 7 against A. flavus and P. chrysogenum respectively after 12 days. The most suitable temperature for the growth of A. flavus and P. chrysogenum was observed on 25°C and 30°C respectively. The fungus showed maximum growth at 90% relative humidity
