广西北部湾海洋弧菌多样性研究进展

Research Progress of Marine Vibrio Diversity in Beibu Gulf of Guangxi

摘要:

海洋弧菌在生物地球化学循环中发挥重要作用，但部分致病性海洋弧菌可危害人类健康和造成水产养殖业重大经济损失。近年来，广西北部湾海洋弧菌多样性研究取得了众多科研成果。然而，关于广西北部湾海洋弧菌多样性系统总结的报道仍较为缺乏。为了更好地了解广西北部湾海洋弧菌物种组成、群落分布特点及其驱动机制，该文从广西北部湾海洋弧菌群落结构特征、环境驱动因子、群落构建机制等方面对广西北部湾海洋弧菌多样性研究进行综述。结果表明，广西北部湾海洋弧菌多样性在不同海域和季节存在显著差异，其主要驱动因子为总溶解氮、溶解性无机氮、总溶解磷等营养盐。广西北部湾海洋弧菌群落构建过程由随机过程主导。此外，该研究对广西北部湾海洋弧菌多样性研究前景进行了展望，以期为致病性海洋弧菌防控提供新思路，并为海洋弧菌生态功能多样性研究及生物资源高值化利用提供理论参考。

Abstract:

Marine Vibrio plays a key role in the biogeochemical cycle, and certain pathogenic marine Vibrios can threaten human health and cause economic loss in the aquaculture industry. In recent years, a lot of achievements have been made in studying the diversity of marine Vibrio in Guangxi Beibu Gulf, though there are still few reports that systematically summarize them. To better understand the species composition, communities distribution characteristics and driving mechanism of the marine Vibrio in the Beibu Gulf of Guangxi, this paper reviewed the research on the diversity of marine Vibrio in the Beibu Gulf of Guangxi based on the community structural characteristics, major environmental driving factors, and the community assembly mechanism. The results showed that the marine Vibrio diversity in Guangxi Beibu Gulf varies with sea area and season, with the main driving factors being nutrients such as total dissolved nitrogen, dissolved inorganic nitrogen, and total dissolved phosphorus. The community assembly process of the Vibrio community in Guangxi Beibu Gulf was dominated by random processes. In addition, this review provides an outlook for future studies on marine Vibrio diversity in Guangxi Beibu Gulf, aiming to provide new ideas for the prevention and control of pathogenic marine Vibrio outbreaks, and provide a theoretical reference for the research on the ecological function diversity of marine Vibrios and the high-value utilization of biological resources.
