海洋水产养殖区正面临着严峻的环境挑战，特别是沿海生态系统的退化。本文采用时间序列研究方法，对黄海近岸浮游细菌生物多样性动态进行了研究。细菌16S rRNA基因序列分析表明，夏季细菌多样性呈下降趋势。功能预测表明，与三磷酸腺苷（ATP）结合盒转运体和其他膜转运体相关的代谢途径在5月显著富集，而遗传信息处理类别在3月最丰富。5月微生物群落与磷酸盐浓度呈显著正相关，8月和11月微生物群落与温度和化学需氧量（COD）呈显著正相关，3月微生物群落与Cu2+、pH和盐度呈显著正相关。本研究揭示的代表性细菌与环境参数之间的相关性可能有助于了解人类水产养殖活动对沿海浮游细菌生物多样性的潜在影响。
Marine aquaculture areas are facing stressed environmental challenges, especially the degradation of coastal ecosystems. Here a coordinated time-series study was used to investigate the coastal bacterioplankton biodiversity dynamics of the Yellow Sea, China. Bacterial 16S rRNA gene sequencing revealed a temporal pattern of decreasing of diversity in summer. Functional prediction indicated that metabolic pathways related to the adenosine triphosphate (ATP)-binding cassette transporters and other membrane transporters were significantly enriched in May, while the genetic information processing category was most abundant in March. The May microbiomes showed most significant positive correlation with phosphate concentration, while the August and November microbiomes correlated with temperature and chemical oxygen demand (COD) most, and the March microbiomes showed significant correlation with Cu2+level, pH and salinity. The correlations between representative bacteria and environmental parameters revealed in this study may provide insights into the potential influences of human aquaculture activities, on the biodiversity of coastal bacterioplankton.
