Bacterial communities in sediments of a drinking water reservoir

Abstract

Sediment microbial communities play crucial roles in biogeochemical cycles of aquatic systems. Knowledge of microbial community structure could aid in our understanding of these roles. In this study, the sediment bacterial community structure of a drinking water reservoir in China was investigated. A large difference in major bacterial groups was observed at different sampling sites. Proteobacteria was the largest bacterial phylum, with a marked shift in the proportions of its major subdivisions. Microorganisms within phylum Proteobacteria might play important roles in various biogeochemical processes. © Springer-Verlag Berlin Heidelberg and the University of Milan 2013.
