为了加深对南海新村湾海藻（Thalassia hernprichii）微生物多样性的了解，采用高效测序法对该海域海藻16 S rRNA基因进行了鉴定。海草T. hernprichii隶属于37门99纲。与海草相关的细菌的多样性在地理上相连的新村湾的沿海位置之间是相似的。变形菌为优势菌，α-变形菌已适应海草生态位。此外，α-变形菌和假单胞菌也是海草草甸的伴生菌群，但细菌与植物的相互作用有待进一步研究。伯克霍尔德菌目和疣微菌目表明了人为活动对海湾的影响。此外，蓝藻可能意味着不同地点的营养条件的差异。γ-变形菌、脱硫菌目和Pirellulales分别在硫循环、有机矿化和草甸生态系统中发挥作用。此外，低丰度细菌在海草草甸中具有重要作用，但缺乏对海草与低丰度细菌相互作用的了解。微生物群落可以对环境做出反应，并在生物化学循环中发挥关键作用。
In order to increase our understanding of the microbial diversity associated with seagrass Thalassia hernprichii in Xincun Bay, South China Sea, 16S rRNA gene was identified by highthrough sequencing method. Bacteria associated with seagrass T. hernprichii belonged to 37 phyla, 99 classes. The diversity of bacteria associated with seagrass was similar among the geographically linked coastal locations of Xincun Bay. Proteobacteria was the dominant bacteria and the alpha-proteobacteria had adapted to the seagrass ecological niche. As well, alpha-proteobacteria and Pseudomonadales were associated microflora in seagrass meadows, but the interaction between the bacteria and plant is needed to further research. Burkholderiales and Verrucomicrobiae indicated the influence of the bay from anthropogenic activities. Further, Cyanobacteria could imply the difference of the nutrient conditions in the sites. gamma-proteobacteria, Desulfobacterales and Pirellulales played a role in the cycle of sulfur, organic mineralization and meadow ecosystem, respectively. In addition, the less abundance bacteria species have key functions in the seagrass meadows, but there is lack knowledge of the interaction of the seagrass and less abundance bacteria species. Microbial communities can response to surroundings and play key functions in the biochemical cycle.
