摘要: 为揭示水动力变化对海洋污损真核微生物群落的影响，通过室外微宇宙实验，采用环境微生物高通量测序技术，研究了不同水动力条件下真核微生物群落组成结构和功能特征。实验检测到真核微生物146个属，隶属18个门。聚类分析表明动静态样品组微生物群落结构明显不同。在水动力条件下，不同材料表面的真核微生物群落中优势门属呈现差异，静态组中线虫动物门为优势门，小单宫属丰度最高；动态组中，对于玻璃钢、铝合金材料，弱动力组表面微生物群落优势菌门为绿藻门，转移组为线虫动物门。强动力组3种材料表面的优势菌门均为定鞭藻门，但强动力组的群落丰富度和多样性较低。此外，水动力影响群落的代谢通路并改变了真核微生物群落物种间的关联性。

Abstract: To reveal the impact of hydrodynamic changes on eukaryotic microbial communities in marine fouling,outdoor microcosm experiments were conducted by employing environmental microbial high-throughput sequencing technology to investigate the compositional structure and functional characteristics of eukaryotic microbial communities under different hydrodynamic conditions. There were 146 genus of eukaryotic microorganisms belonging to 18 phylum detected. Clustering analysis reveals significant differences in the microbial community structures between dynamic and static sample groups. The dominant phyla and genera in eukaryotic microbial communities varied under different materials and hydrodynamic conditions. Specifically, in the static group, the phylum Nematoda was dominant, with the genus Mononchus being the most abundant. In the dynamic group the dominant microbial phylum on the surface of the weak hydrodynamic group was Chlorophyta on the materials of fiber reinforced plastics and aluminum alloy, while it was Nematoda in the transferred group.The dominant microbial phylum on the surfaces of the strong hydrodynamic group on all the three materials was Haptophyta, but the community richness and diversity were lower in the strong hydrodynamic group. Cluster analysis revealed significant differences in microbial community structure between dynamic and static sample groups. Moreover, there were differences in metabolic pathways among communities under different hydrodynamic conditions, indicating that changes in hydrodynamic conditions also altered the correlations among species in the eukaryotic microbial community.
