Cyanophages are highly abundant specific viruses that infect cyanobacterial cells. In recent years, the cyanophages and cyanobacteria interactions drew attention to environmental restoration due to their discovery in marine and freshwater systems. Cyanobacterial harmful algal blooms (cyanoHABs) are increasing throughout the world and contaminating aquatic ecosystems. The blooms cause severe environmental problems including unpleasant odors and cyanotoxin production. Cyanotoxins have been reported to be lethal agents for living beings and can harm animals, people, aquatic species, recreational activities, and drinking water reservoirs. Biological remediation of cyanoHABs in aquatic systems is a sustainable and eco-friendly approach to increasing surface water quality. Therefore, this study compiles the fragmented information with the solution of removal of cyanoHABs using cyanophage therapy techniques. To date, scant information exists in terms of bloom formation, cyanophage occurrence, and mode of action to remediate cyanoHABs. Overall, this study illustrates cyanobacterial toxin production and its impacts on the environment, the mechanisms involved in the cyanophage-cyanobacteria interaction, and the application of cyanophages for the removal of toxic cyanobacterial blooms.
噬蓝藻体是感染蓝藻细胞的高度丰富的特异性病毒。近年来，噬蓝藻体与蓝藻之间的相互作用因其在海洋和淡水系统中的发现而受到环境修复领域的关注。全球范围内，蓝藻有害藻华（cyanoHABs）正在增加，并污染着水生生态系统。这些藻华引发了包括难闻气味和蓝藻毒素产生在内的严重环境问题。据报道，蓝藻毒素是生物的致命因子，会危害动物、人类、水生物种、娱乐活动以及饮用水源。对水生系统中的蓝藻有害藻华进行生物修复是提高地表水质量的一种可持续且环保的方法。因此，本研究整合了零散信息，并介绍了利用噬蓝藻体疗法去除蓝藻有害藻华的解决方案。迄今为止，关于藻华形成、噬蓝藻体的存在情况以及修复蓝藻有害藻华的作用方式，相关信息匮乏。总体而言，本研究阐述了蓝藻毒素的产生及其对环境的影响、噬蓝藻体与蓝藻相互作用的机制，以及噬蓝藻体在去除有毒蓝藻藻华方面的应用。
