Bacterial Community Structure and Its Influence Factors of the Groundwater in an Industry Park
摘要
Abstract
The structure and diversity of bacterial community in groundwater are important indicators to reflect the environmental sensitivity of the ecosystem. In order to investigate the bacterial community structure and diversity of the groundwater in an industrial park, the groundwater samples from an industrial park in Changzhou were collected in December2016, and the 16 S rRNA gene of bacteria was sequenced by high-throughput sequencing. The results show that bacterial community structure of the groundwater present a typical characteristics of freshwater populations and could be divided into55 phyla, 95 classes and 564 genera. Proteobacteria (86. 40％), Bacteroidetes (5. 06％) and Firmicutes (3. 04％) are the dominant phyla in the studied groundwater. The abundant classes within the phyla Proteobacteria are Gammaproteobacteria (47. 51％), Betaproteobacteria (29. 58％) and Alphaproteobacteria (6. 75％), respectively. At the genus level, Pseudomonas (16. 38％), Perlucidibaca (9. 17％) and Acinetobacter (8. 12％) are predominant. The influence of the physical and chemical indicators on bacterial community show that the water quality affects the composition and diversity of bacterial community, and the better the water quality is, the higher the richness and evenness of bacterial community are.Redundancy analysis results show that chloride, calcium, conductivity, iron, fluoride and sulfate are the environmental factors that can significantly explain the groundwater bacterial community.关键词
