虽然某些种类的海藻对微生物群落结构的影响长期以来一直是海洋生态学的研究热点，但微生物群落对季节和不同海藻种类的响应却知之甚少。在3个月的时间里，从坛新紫菜（Neoporphyrahaitanensis）养殖区（P）、龙须菜（Gracilarialemaneiformis-Gracilinajaponica）混养区（G）和对照区（C）共采集了39个海水样品。然后，这些样品进行了分析，使用18 S和16 S rRNA基因测序，以确定真菌和细菌群落，分别与环境因素的测定沿着。结果表明，海藻养殖区溶解氧（DO）增加，无机营养盐减少，溶解有机物（DOM）释放，显著改变了真核和原核微生物群落的多样性。某些微生物群，如Aurantivirga，假单胞菌属，和Woeseia刺激和丰富的响应海藻栽培，和丰富的微生物不同海藻栽培区由于释放的DOM的组成的差异。此外，盐度和温度的季节变化与微生物群落组成和结构密切相关。我们的研究为海藻和微生物群落之间的相互作用提供了新的见解。
Although the effects of certain species of seaweed on the microbial community structure have long been a research focus in marine ecology, the response of the microbial community to seasons and different seaweed species is poorly understood. In the present study, a total of 39 seawater samples were collected during 3 months from three zones: Neoporphyra haitanensis cultivation zones (P), Gracilaria lemaneiformis-Saccharina japonica mixed cultivation zones (G), and control zones (C). These samples were then analyzed using 18S and 16S rRNA gene sequencing to ascertain the fungal and bacterial communities, respectively, along with the determination of environmental factors. Our results showed that increased dissolved oxygen (DO), decreased inorganic nutrients, and released dissolved organic matter (DOM) in seaweed cultivation zone predominantly altered the variability of eukaryotic and prokaryotic microbial communities. Certain microbial groups such as Aurantivirga, Pseudomonas, and Woeseia were stimulated and enriched in response to seaweed cultivation, and the enriched microorganisms varied across seaweed cultivation zones due to differences in the composition of released DOM. In addition, seasonal changes in salinity and temperature were strongly correlated with microbial community composition and structure. Our study provides new insights into the interactions between seaweed and microbial communities.
