微囊藻与水体细菌相互关系的研究进展

近年来, 微生物群落在水生态系统中的结构和功能受到了越来越多的关注。在富营养化水体中细菌在微囊藻水华的发生、发展及衰亡、降解过程中发挥着重要的作用。文章总结了水体中微囊藻与细菌独有的群落结构特征,以及微囊藻与细菌群落对环境因素变化的响应等方面的研究成果。在微囊藻与细菌的相互作用方面, 从藻细胞微环境中附着细菌对微囊藻生长的促进或抑制作用, 细菌在微囊藻群体的形成和维持过程的作用, 细菌参与的微囊藻水华的聚集和降解过程, 细菌对微囊藻毒素的降解作用等方面进行了综述。文章还对未来微囊藻与细菌相互关系的研究热点以及可利用的组学技术等进行了展望。

PROGRESS IN THE RELATIONSHIPS BETWEEN MICROCYSTIS AND AQUATIC BACTERIA

The structure and function of microbial communities in aquatic ecosystems have been widely reported. In eutrophic waters, bacteria play an important role in the occurrence, development, decline and degradation of Microcystis blooms. In this paper, we described the unique characteristics ofMicrocystisand bacterial communities in the water column and sediment, as well as the responses of the dynamics of Microcystis and bacterial communities to environmental factors. Furthermore, the interactions between Microcystis and bacteria were summarized from the following aspects: first, attached bacteria can mediate the growth of Microcystis in the microenvironment of algal cells. Second, bacteria are involved in the formation and maintenance of Microcystis colonies. Third, bacteria regulate the aggregation and degradation of Microcystis blooms. Fourth, the bacterial degradation of microcystins was introduced. Finally, the future research focus of the relationships betweenMicrocystisand bacteria and the available omics technology were prospected.
