摘要/Abstract

摘要： 研究旨在明确南京市不同功能区大气降尘中的微生物多样性分布规律，为控制某些空气传播的微生物病原菌提供理论依据。采用3种空气采样方法对比，通过PCR扩增、基因克隆、RFLP和序列分析对南京市3个不同功能区(NAU, NBG, XWG)的空气降尘进行细菌16S rDNA及真菌18S rDNA分析。结果显示，芽孢杆菌属(Bacillus)，假单孢菌属(Pseudomona)及微球菌属(Micrococcus)在南京春季空气细菌中占比较大；而青霉属(Penicillium)、曲霉属(Aspergillus)、链格菌属(Alternaria)及挫孔菌属(Sistotrema)是真菌优势菌属。同时，空气微生物中也存在粘质沙雷氏菌等条件致病菌。该试验确定了春季南京市不同功能区细菌真菌丰度及多样性分布规律，为江苏省乃至全国对空气质量的监测及对大气微生物的研究提供了可行性方法。

Abstract: The study aimed at finding the distribution regularities of atmospheric microbes in different functional regions in Nanjing, thus to provide theoretical evidences for controlling some air-borne pathogenic bacteria. We collected air samples using three methods from three domains (NAU, NBG, XWG) and conducted further analysis. Diversity and concentration of bacterial 16S rDNA and fungal 18S rDNA in three functional areas of Nanjing were analyzed by PCR amplification, gene clone, RFLP (restricted fragment length polymorphisms) and sequence analysis. The results showed that air samples derived from the three domains collected from the spring of Nanjing were dominated by bacteria such as Bacillus, Micrococcus and Pseudomona and Alternaria, Penicillium, Aspergillus and Sistotrema were common fungi as well. Meanwhile, the conditioned pathogens such as serratia marcescens were detected. In general, the abundance and diversity distribution regularities of bacteria as well as fungi in different domains in spring of Nanjing were confirmed, and the study provided a feasible way for air quality monitoring and atmospheric microorganism research in Jiangsu Province and the whole country.
