中文摘要 致嗅微生物主要包括放线菌、藻类和黏细菌等，广泛存在于水源水库、湖泊、溪流和海洋等典型水生态系统中，代谢产生的异嗅化合物痕量即可造成严重的异嗅味，威胁供水安全.目前，大量研究集中在异嗅化合物的有效控制上，投入使用的有物理和化学等方法，但存在问题，有待改进与完善，微生物法对环境友好，因此具有广阔的应用前景.本文从异嗅化合物的种类、生物源、检测方法、控制措施、影响因素及产嗅机制等方面的研究进行综述，并进行展望，讨论今后研究热点，旨在推进异嗅化合物的相关研究，保障城镇供水安全. 英文摘要 Olfactory microorganisms mainly include actinomycetes, algae, and myxobacteria, and are widely found in typical water ecosystems such as water source reservoirs, lakes, streams, and oceans. Biologically-derived taste and odor compounds can cause severe off-flavor problems at trace concentrations, threatening the safety of water supplies. Physical and chemical methods have been implemented, but they need to be improved and optimized. Microbial methods show attractive prospects due to their environmentally friendly characteristics. This article reviews the literature regarding the types, biological sources, detection methods, control measures, influencing factors, and odor-producing mechanisms of microbial methods. Future research directions and fields of investigation are discussed in order to promote the related research of taste and odor compounds and ensure the safety of urban water supplies.
