Bromate is a disinfection byproduct (DBP) that forms during the ozonation of bromide-containing natural water, which may cause health risks to humans. In this review, we provide an overview of the mechanism of bromate formation, microbial communities and bioreactors that are responsible for bromate reduction. Bromate can be formed through two pathways of bromide oxidation by ozone or by OH, and it can be removed by biological approaches. Members belonging to phyla of Spirochaetes, Proteobacteria, Firmicutes, Actinobacteria, Clostridium, Deinococcus-Thermus and Bacteroidetes have been identified as capable of reducing bromate to bromide. Multiple configurations of biofilm bioreactors have been employed to cultivate microbial communities to perform bromate removal. The rapid development of multiomics has and will continue to accelerate the elucidation of the mechanisms involved in bromate and other DBP conversions, as well as the interaction patterns among different bacterial subdivisions in the bioremoval of DBPs.
溴酸盐是一种消毒副产物（DBP），在含有溴化物的天然水的臭氧氧化过程中形成，可能对人类健康造成风险。在这篇综述中，我们概述了溴酸盐形成的机制、负责还原溴酸盐的微生物群落和生物反应器。溴酸盐可以通过臭氧或 OH 氧化溴化物的两种途径形成，并且可以通过生物方法去除。属于螺旋体门、变形菌门、厚壁菌门、放线菌门、梭菌门、古菌门和拟杆菌门的成员已被确定能够将溴酸盐还原为溴化物。已经采用了多种生物膜生物反应器的配置来培养微生物群落以进行溴酸盐去除。多组学的快速发展已经并将继续加速阐明涉及溴酸盐和其他消毒副产物转化的机制，以及在消毒副产物的生物去除过程中不同细菌亚群之间的相互作用模式。
