Anthraquinone dyes, which contain anthraquinone chromophore groups, are the second largest class of dyes after azo dyes and are used extensively in textile industries. The majority of these dyes are resistant to degradation because of their complex and stable structures; consequently, a large number of anthraquinone dyes find their way into the environment causing serious pollution. At present, the microbiological approach to treating printing and dyeing wastewater is considered to be an economical and feasible method, and reports regarding the bacterial degradation of anthraquinone dyes are increasing. This paper reviews the classification and structures of anthraquinone dyes, summarizes the types of degradative bacteria, and explores the possible mechanisms and influencing factors of bacterial anthraquinone dye degradation. Present research progress and existing problems are further discussed. Finally, future research directions and key points are presented.
蒽醌染料含有蒽醌生色团，是继偶氮染料之后的第二大染料类别，广泛应用于纺织工业。由于其复杂和稳定的结构，这些染料中的大多数都难以降解；因此，大量的蒽醌染料进入环境会造成严重的污染。目前，微生物处理印染废水被认为是一种经济可行的方法，有关细菌降解蒽醌染料的报道也越来越多。本文综述了蒽醌染料的分类和结构，总结了降解菌的类型，探讨了细菌降解蒽醌染料的可能机制和影响因素，并进一步讨论了目前的研究进展和存在的问题。最后提出了未来的研究方向和重点。
