Culturable bacteria were isolated from surface seawater in Daya Bay, and identified by means of 16S rRNA gene V3 region sequences. A phylogenetic tree was constructed using 35 sequences in this study and 46 sequences from GenBank. Seventy bacterial isolates were isolated and cultured from surface water of 9 stations in Daya Bay, which were classified into 35 categories. Within them, 40% belonged to Alphaproteobacteria, 35.7% to Actinobacteria, and 1.4% to Betaproteobacteria. Meanwhile, two genera, Kytococcus and Intrasporangium, which were rarely reported, were also isolated. The value of Shannon-Wiener`s index was 3.21, indicating a diversity of bacteria in Daya Bay. The high diversity of the culturable bacteria and abundance of Alphaproteobacteria suggested the good water quality and the potential microbial resources in Daya Bay.
