Abstract

Airborne bacteria are important biological components of bioaerosol and play an important role in ecosystem Bacteria at a high concentration in the atmosphere can result in biological air pollution and all kinds of diseases In this study a systematical survey on the culturable airborne bacteria was carried out for 1 year at three sites in Beijing urban area Results showed that concentrations of culturable bacteria ranged from 71 colony forming units CFU/m3 to 22100 CFU/m3 and the mean was 2217 CFU/m3 Bacterial concentrations at the human activityenriched site RCEES and the highly trafficked site XZM were virtually the same point They were significantly higher than those at the greener site BBG Significant variation in bacterial concentrations in different seasons was observed at RCEES and XZM with higher concentrations in summer and autumn In a single day significantly lower concentrations were detected at 1300 hours through all sampling sites In this study 165 species in 47 genera of culturable bacteria were identified Micrococcus was one of the most dominant bacterial groups and contributed to approximately 20∼30 of the total bacterial concentration followed by Staphylococcus Bacillus Corynebacterium and Pseudomonas The bacterial species with a high concentration percentage included Micrococcus luteus and Micrococcus roseusThis study was financially supported by the Project of Knowledge Innovation of the Chinese Academy of Sciences KZCX3SW424 The authors would like to gratefully acknowledge Haicun Gao from the Institute for Environmental Genomics IEG Department of Botany and Microbiology University of Oklahoma in the USA who made technical and grammatical revision for this article successful The authors also thank other graduate students and teachers who provided their valuable suggestions in our research group and in the department of systems ecology in the research center for EcoEnvironmental Sciences Chinese Academy of Sciences
