The water bodies, mainly coastal and lake, remain tainted worldwide, mostly because of the Cyanobacteria harbored in Harmful Algal Blooms (HABs). The main reason for the flourishing of blooms depends on the eutrophication. Blooms could be toxic as well as non-toxic, depending on the bloom-forming species. The blooms affect the water body, aquatic ecosystem and also dependents like human. A large number of organisms, including bacteria, viruses, fungi, fish and zooplankton have adverse effects on Cyanobacteria either through infection, predation or by the production of the algicidal compounds. It was reported, these microorganisms have species-specific interactions and hence differ in their interaction mechanism. The present review emphasises on the role of selected microbial species and the mechanism they follow for mitigation of HABs. Generally lab-scale entities were reported to involve lytic agents, like cyanobacteriolytic substances, released by bacteria. Cyanobacterial species release Cyanotoxins which may affect the water quality. Growing biotic factors in a large quantity and discharging it into the water-body needs excessive efficacy and economic requisite and hence the feasibility of extrapolation of the laboratory results in the field still finds promiscuity towards mitigation of HABs.

有害藻华（HABs）的生物控制：简要回顾。

水体，主要是沿海和湖泊，在世界范围内仍然受到污染，主要是因为有害藻华（HABs）中藏有蓝藻。水华盛放的主要原因取决于富营养化。根据形成水华的物种，水华可能是有毒的，也可能是无毒的。水华会影响水体，水生生态系统以及人类等生物。包括细菌，病毒，真菌，鱼类和浮游动物在内的许多生物通过感染，捕食或产生杀藻化合物对蓝细菌产生不利影响。据报道，这些微生物具有种特异性相互作用，因此它们的相互作用机理不同。本综述着重介绍所选微生物物种的作用及其对减轻HAB遵循的机制。据报道，一般实验室规模的实体都涉及细菌释放的裂解剂，如蓝细菌分解物质。蓝细菌释放出可能影响水质的氰毒素。大量生长生物因子并将其排放到水体中需要过多的功效和经济需求，因此，在该领域外推实验室结果的可行性仍然发现减轻HAB的可能性。
