【摘要】：选取杭州市4个样点进行了空气微生物取样,利用传统可培养法系统研究了其空气微生物特征.结果表明杭州市空气微生物总浓度变化范围为24~10135CFU/m~3.均值为1140CFU/m~3,空气细菌浓度变化范围为0~3253CFU/m~3,均值为292CFU/m~3,空气真菌浓度变化范围为0~8767CFU/m~3,均值为848CFU/m~3.空气真菌浓度显著高于细菌浓度.空气细菌和真菌浓度百分比分别为29.1%和70.9%.杭州市不同样点空气微生物中浓度显著不同,ZJGSUJC最高为1413CFU/m~3,其次为YRBS(1174CFU/m~3)和BLQG(1137CFU/m~3),TJCR最低为834CFU/m~3.杭州室外优势细菌属依次为微球菌属(Micrococcus)、芽孢杆菌属(Bacillus)、葡萄球菌属(Staphylococcus)、库克菌属(Kocuria)和假单胞菌属(Pseudomonas),5属细菌百分比总和约占55.26%~59.48%.优势真菌属依次为青霉属(Penicillium)、枝孢属(Cladosporium)、链格孢属(Alternaria)、无孢菌和曲霉属(Aspergillus),分别约占总数的29.49%、21.43%、10.98%、10.88%和7.74%.本研究提供了杭州市空气微生物污染的第一手资料,为城市管理部门制定相关的环境政策法规提供理论指导,也为全面掌握我国城市空气微生物特征奠定基础.
[Abstract]:Sampling of microorganism in air was carried out at 4 sampling sites in Hangzhou. The results show that the variation range of total microorganism concentration in Hangzhou is 24 ~ 10135 CFU / m ~ (3), the mean value is 1140 CFU / m ~ (3), the variation range of air bacterial concentration is 0 ~ 3253 CFU / m ~ (3), the mean value is 292 CFU / m ~ (3), the density of air fungi is changing. The average value is 848 CFU / mt3. The air fungal concentration is significantly higher than bacterial concentration. The percentages of air bacterial and fungal concentrations are 29.1% and 70.9 respectively. The highest concentration of ZJGSUJC is 1413 CFU / m3 at different points in Hangzhou, followed by YRBSU 1174 CFU / M3). The lowest TJCR in Hangzhou was 834 CFU / m ~ (3). The dominant bacteria genera in Hangzhou were Micrococcus, Bacillusus, Staphylococcus, Kocuriaand Pseudomonas, and Pseudomonas spp., respectively. The dominant fungi were Penicillium and Penicillium, respectively. Cladosporium, Alternaria, aspergillus and Aspergillus, accounting for 29.49% and 21.4310.98% of the total, respectively, and 7.74%, 10.88% and 7.74%, respectively. It provides theoretical guidance for urban management departments to formulate relevant environmental policies and regulations, and lays a foundation for mastering the characteristics of microorganism in urban air in China.
