Abstract

We explored the bacterial diversity and vertical distribution along a sediment core (MD05-2896) from the coral reefs of the Nansha carbonate platform in the South China Sea. Bacterial diversity is determined by 16S rRNA molecular survey from twelve subsamples A, obtained via cloning, sequencing and phylogenetic analyses. We estimated the species richness by parametric and nonparametric models, which identified 326 ± 40 (SE) bacteria species. The dominant bacterial groups included Planctomycetes, Deltaproteobacteria, and candidate division OP3, which constituting 23.7, 10.4, and 9.5 % of bacterial 16S rRNAclone libraries, respectively. The observed stratification of bacterial communities was correlated with C/N ratio. This study improves our understanding of the species-environment relationship in the sub-sea floor sediment.
