The textile industry uses large amounts of dyes like reactive, azo, anthraquinone, and triphenylmethane to colour textiles. Dyes that are not used up during the colouration process usually end up in water bodies as waste leading to the pollution of the water bodies. This makes the industry to be one of the major contributors to water pollution in the world. Bacterial agents isolated from various sources like dye contaminated soil and textile wastewater have shown to have the ability to effectively decolourise and degrade these dye pollutants leading to improved water quality. This review discusses bacterial isolates that have been used successfully to degrade and decolourise textile dyes, their mode of dye removal as well as the factors that affect their dye degradation ability. It further looks at the latest wastewater treatment technologies that incorporate bacterial microorganisms to treat dye wastewater.
纺织工业使用大量如活性染料、偶氮染料、蒽醌染料和三苯甲烷染料等来给纺织品染色。在染色过程中未被消耗的染料通常会作为废物最终进入水体，导致水体污染。这使得该行业成为全球水污染的主要贡献者之一。从各种来源（如受染料污染的土壤和纺织废水）分离出的细菌制剂已显示出能够有效使这些染料污染物脱色和降解，从而改善水质。本综述讨论了已成功用于降解和使纺织染料脱色的细菌分离物、它们的染料去除模式以及影响其染料降解能力的因素。它还进一步探讨了结合细菌微生物来处理染料废水的最新废水处理技术。
