Abstract The characteristics of airborne microbes were carried out detailedly by culture-dependent method at four typical sampling sites in Hangzhou. Results showed that the concentration of total microbes, bacteria, and fungi ranged from 24 to 10135CFU/m3, 0 to 3252CFU/m3, 0 to 8767CFU/m3, respectively, and the mean concentration was 1140, 292, and 848CFU·m-3, respectively. In general, the concentration of airborne bacteria was significantly higher than that of airborne fungi, and the concentration percentage of airborne bacteria and fungi was 29.1% and 70.9%, respectively. Significant difference of airborne microbes was observed at different sampling sites in Hangzhou, and the maximum concentration was found at ZJGSUJC (1413CFU/m3), followed by YRBS (1174CFU/m3) and BLQG (1137CFU/m3), with a minimum at TJCR (834CFU/m3). Amongst all the airborne bacteria, Micrococcus was the most dominant bacterial genus, followed by Bacillus, Staphylococcus, Kocuria and Pseudomonas, all of these five bacteria genera accounted for about 55.26% to 59.48% of total airborne bacteria. The predominant fungal genera were Penicillium (29.49%), Cladosporium (21.43%), Alternaria (10.98%), Mycelia sterilia (10.88%), and Aspergillus (7.74%), respectively. Results provide the first-hand information on airborne microbes in Hangzhou, and provide theoretical guidance for city management departments to develop relevant environmental policies and regulations, and also lay a foundation for the overall grasp of urban microbial characteristics in the air in China.
