有害微藻抑藻细菌多样性及抑藻机制研究进展

Diversity of algicidal bacteria associated with harmful microalgae and the algicidal mechanisms

摘要:

有害藻暴发能够破坏水生生态系统，对水环境、人类健康及各国经济构成严重威胁。寻找能够有效防治有害藻华或赤潮的方法是现阶段水生生态保护与修复领域的重要研究内容之一。其中，微生物因其分布广、种类多和易繁殖等特点，在有害藻华或赤潮防治方面表现出巨大潜力，正逐渐得到广泛关注。本文从抑藻细菌分布、物种多样性及抑藻机制(抑藻方式、细胞形态、光合作用和氧化损伤)等角度对当前有害微藻抑藻细菌研究进展进行梳理总结，为微生物控藻提供理论参考。

Abstract:

Harmful algal blooms (HABs) pose a serious threaten to water environment because of the released toxic substances and dramatic underwater light reduction. How to control HABs is attractive and has attracted worldwide attentions. Among them, microorganisms show great application potential in prevention and control of HABs because of the fast growth, easy propagation and rapid metabolism. Here, we summarized the distribution and diversity of isolated algicidal bacteria and the underlying algicidal mechanisms (algicidal mode, cell morphology, photosynthesis, and oxidative damage).
