近年来，在甲藻、针藻、硅藻等有害藻华盛期及盛期后，发现了病毒、细菌、阿米巴原虫等多种杀藻微生物。这些微生物分为两大类：滑行细菌和变形虫在细胞与细胞附着后直接攻击宿主藻类细胞，以及真细菌通过这些细菌分泌的有毒物质杀死或溶解这些藻类。前者有噬细胞菌属、滑行菌腐螺菌属和迷宫菌属，后者有黄杆菌属、交替单胞菌属、弧菌属等。一些杀藻物质已被分离和纯化，但尚未鉴定。为了研究藻华期间杀藻细菌的行为，对16S rDNA进行了RFLP分析，17种RFLP类型中的4种通常构成了赤潮异形藻赤潮解体的主要菌群。正在研究使用 RFLP 模式和 16 S rDNA 的 DNA 探针和单克隆抗体作为生态研究和预防有害藻华的生态工具。
Recently many species of algicidal microorganisms including viruses, bacteria, amoeba etc. have been detected in and after the peak of the harmful algal blooms such as dinoflagellates, raphidophytes and diatoms. These microorganisms are divided into two major types: gliding bacteria and amoeba which directly attack host algal cells after cell-to-cell attachment, and eubacteria which kill or lyse these algae through toxic substances excreted by these bacteria. The former are Cytophaga, Saprospira as gliding bacteria and Labyrinthula, while the latter are Flavobacterium, Alteromonas, Vibrio and others. Some algicidal substances have been isolated and purified, but are not yet identified. To investigate the behavior of algicidal bacteria during algal bloom, the RFLP analysis of 16 S rDNA was conducted, and 4 of 17 RFLP types usually comprised the major flora in the disintegration of Heterosigma akashiwo red tide. Use of RFLP patterns and DNA probes of 16 S rDNA and monoclonal antibodies as an ecological tool for ecological research and prevention of harmful algal blooms is being studied.
