Abstract
Fungi, including allergenic, pathogenic or toxigenic species, may have direct effects on human health, interfere with the disinfection process and maintenance of chlorine residual, and add to taste and odor problems. We surveyed distribution of waterborne fungi from raw water in Busan metropolitan city using the EPA standard method. According to the survey, conducted from March 2008 to October 2008, the number of fungi in raw water was high in September and low in April. Quantitative enumeration of fungi per 100 ml of raw water ranged from 5 to 64 CFU, and a higher number was detected in the Mulgum region compared to the Maeri region. Total fungi numbers highly correlated with pH, water temperature and total coliform in this area. Predominant fungi genera grown in medium were identified as Aspergillus, Penicillum, Histoplasma, Rhizopus, Trichophyton, Mucor and Sporthrix species. Aspergillus flavus and Penicillum notatum were particularly dominant in both areas. There were a total of 6 and 9 species detected in the Mulgum and Maeri regions respectively, and the number of species was more verified in the Maeri region than the Mulgum region.
