[中文摘要]赤潮是一种严重的全球性海洋自然灾害,近年来赤潮发生次数增多,发生区域扩大,危害加剧。放线菌是产生生物活性物质相对较多的一类微生物,溶藻放线菌的发现及其代谢产物多样性,在赤潮生消过程中起着越来越重要的作用,为微生物防治赤潮及新型杀藻剂的开发提供了可能。采用溶藻微生物进行赤潮和水华的防治已经被深入认识和充分肯定,成为当前赤潮研究的重点和热点。概述了溶藻放线菌发现及其活性物质分离筛选的研究进展以及赤潮防治的新方法,强调了放线菌及其代谢产物在生态环境中的重要作用,提出了利用放线菌防治赤潮的可能性及有效性,并对溶藻放线菌及其活性物质的研究趋势和应用前景进行了展望。[英文摘要]The dram atically increasing occurrence of harmful algal blooms (HABs) a ll over the world has at tracted a great dea l of a ttentions from researchers tying to mitigate the blooms. Some management strategies have been developed such as flocculation of microalgae with clay, biological agents. It is now fully convinced that blooms can be controlled and exorcised through microorganism, which has already become the hot issue. All we know is that actinomycete is a kind of microorganism producingmuch more bioactive substance relatively. Based on the var-ieties and high complexity of me tabo lites, actinomyces with algicida l features are playing more and more important role inHAB s. It is possible that alg icida l act inomyces will contribute to exploring new algicidal agents andm it igating the blooms. In th is paper, the find ing of a lgicidal actinomycetes and screening of bioactive substance, as well as new methods for controlling blooms are reviewed. Also, it focuses on the current deve lopment in the research o f a ig-icida l actinomycetes and algicida l substances and refers to possibility and sign if icance of algicidal actinomycetes maginiting blooms. A t las,t the paper prosoects the research trendency and application of research ing a lg icida l act-i nomycetes and relevant bioact ive substances. Th is implies exploring and find ingvarious mechan isms will be a long period and and will provide a better understanding of close beneficia l interactions between algae and actinomycetes in favor of the effect of theseing teractions on algal blooms.
