The discharge of wastewater from textile industries into aquatic bodies has severe health and environmental impacts. Textile industries generate huge amounts of effluents containing hazardous toxic dyes. Anthraquinone (AQ) dyes containing AQ chromophore groups are the second most important class of nondegradable textile dyes, preceded by azo dyes. Despite their prevalence, biodegradation of AQ dyes has not yet been completely understood because of their complex and stable structures. Currently, microbiological approaches to treating dyeing wastewater are considered economical and feasible, and reports regarding fungal degradation of AQ dyes are increasing. Structures and classification of AQ dyes were summarized in this study along with degradative fungi, and their enzyme systems with influencing factors and possible mechanisms of AQ mycoremediation were explored. Furthermore, the existing problems and present research progress were discussed. Finally, the key points with future research directions were presented.
纺织工业向水体排放废水对健康和环境有着严重影响。纺织工业产生大量含有有害有毒染料的废水。含有蒽醌（AQ）发色团的蒽醌染料是第二大类不可降解的纺织染料，仅次于偶氮染料。尽管它们很常见，但由于其结构复杂且稳定，蒽醌染料的生物降解尚未被完全理解。目前，处理印染废水的微生物方法被认为是经济可行的，并且关于真菌降解蒽醌染料的报道也在增加。本研究总结了蒽醌染料的结构和分类以及降解真菌，探讨了它们的酶系统、影响因素和蒽醌真菌修复的可能机制。此外，还讨论了现存问题和当前的研究进展。最后，提出了未来研究方向的关键点。
