微生物降解偶氮染料的研究进展

Research progress in the microbial degradation of azo dyes

偶氮染料广泛应用于纺织印染、造纸印刷等行业,产生的染料废水严重污染环境。近年来,利用微生物(细菌、真菌、藻类)对偶氮染料进行脱色降解的研究报道很多。介绍了最近几年染料废水脱色降解研究中涉及到的微生物,并探讨了相关微生物对偶氮染料的脱色降解作用及其机理,旨在为运用微生物对偶氮染料废水进行脱色处理和降解研究提供参考和依据。

Azo dyes are widely used in textile dying ,paper printing and other industries. The release of dye waste- water causes serious environmental pollution. In recent years ,there has been an intensive research on microbial de- colorization of dye wastewater, including bacteria, fungi, algae, etc. The function and mechanism of microbial decolo- rization and degradation of azo dyes based on the newest progress in the decolorization using microorganisms are dis- cussed, so as to provide some reference and bases for the studies on microbial decolorization and degradation of azo dyes wastewater.
