Abstract:
Objective To understand the pollution of fungi in natural mineral water sources for drinking. Methods Sampling was carried out in 73 natural mineral water sources supplying water for 69 manufactories of bottled mineral water for drinking. Results 982 strains of fungi were found in 45 water samples (61.64%) of the total 73 water samples. Fungi imperfect! revealed the highest detected rates. Phycomycetea, Ascomycetes, Basidiomycetes were all detected, but less frequently. Among 18 detected fungal genera, Aspergillus and Cladosporium were all the dominant genera, as well as Penicilliurn, Trichoderma and Fusarium were commonly detectable genera. No correlations were observed between the detected rates of fungus and total count of bacteria, total coliform, the concentrations of nitrite in source water. Conclusion The extragenous fungal contamination in the process of post-extraction might be the main factor resulting in the pollution of fungi in natural mineral water source.
