Intrahabitat Differences in Bacterial Communities Associated with Corbicula fluminea in the Large Shallow Eutrophic Lake Taihu.

ABSTRACT: The Asian clam Corbicula fluminea is a keystone zoobenthos in freshwater ecosystems. However, its associated microbiome is not well understood. We investigated the bacterial communities of this clam and its surrounding environment, including sediment and water simultaneously, in a large lake by means of 16S rRNA gene sequencing. Approximately two-thirds of the bacterial operational taxonomic units (OTUs) associated with clams were observed in the surrounding environment and mostly from particle-associated samples. The associated bacterial communities were site specific and more similar to environmental bacteria from the same site than those at other sites, suggesting a local environmental influence on host bacteria. However, the significant differences in bacterial diversities and composit
