虽然水产养殖提供了稳定和高质量的食物来源，但与大规模工业化水产养殖活动有关的环境影响已引起关注。为了确定水产养殖活动对沉积细菌群落的影响，我们收集了一系列的网站进行不同强度的水产养殖活动在东太湖，中国的表层和深层沉积物。测定了沉积物中相关理化性质，并应用16S rRNA基因测序技术对沉积物中相关细菌群落进行了分析。表层沉积物中的细菌群落的多样性和组成与深层沉积物样品中的细菌群落有显著差异。也发现了显着的差异之间的表层沉积物的水产养殖的影响和非水产养殖的影响网站。更重要的是，系统发育结构分析表明，随机过程占主导地位的组装的细菌群落，然而，确定性过程的相对贡献是在水产养殖区比在非水产养殖区更大的细菌群落组装。此外，我们确定了总磷（TP）作为最重要的因素驱动的组装细菌群落的影响，水产养殖在沉积物中。这些研究结果为水产养殖影响的生态系统的生态评估和修复策略提供了有用的信息。
Although aquaculture provides a stable and high-quality source of food, the environmental effects related to large-scale industrial aquacultural activities have raised concern. To identify the influence of aquacultural activities on sedimentary bacterial communities, we collected surface and deeper sediments from a series of sites subjected to varying intensities of aquacultural activities within Eastern Lake Taihu, China. The associated physicochemical properties were measured, and 16S rRNA gene sequencing was applied to determine the related bacterial communities in sediment. The diversity and composition of bacterial communities within the surface sediments differed significantly from those of the deeper sediment samples. Marked differences were also found between the surface sediments of the aquaculture-influenced and non-aquaculturally influenced sites. More importantly, phylogenetic structure analysis indicated that stochastic processes dominated the assembly of the bacterial communities; yet, the relative contribution of deterministic processes to bacterial community assembly was greater in the aquacultural zones than in the non-aquacultural zones. Furthermore, we identified total phosphorus (TP) as the most important factor driving the assembly of bacterial communities influenced by aquaculture in sediment. These findings provide useful information for ecological assessments and remediation strategies for aquaculture-influenced ecosystems.
