The coloured effluents produced from different industries, such as textile, plastics, printing, cosmetics, leather and paper, are extremely toxic and a tremendous threat to the aquatic organisms and human beings. The removal of coloured dye pollutants from the aqueous environment is a great challenge and a pressing task. The growing demand for low-cost and efficient treatment approaches has given rise to alternative and eco-friendly methods, such as biodegradation and microbial remediation. This work summarizes the overview and current research on the remediation of dye pollutants from the aqueous environment by microbial bio-sorbents, such as bacteria, fungi, algae, and yeast. In addition, dye degradation capabilities of microbial enzymes have been highlighted and discussed. Further, the influence of various experimental parameters, such as temperature, pH, and concentrations of nutrients, and dye, has been summarized. The proposed mechanism for dye removal by microorganisms is also discussed. The object of this review is to provide a state-of-the-art of microbial remediation technologies in eliminating dye pollutants from water resources.
不同行业（如纺织、塑料、印刷、化妆品、皮革和造纸）产生的有色废水极具毒性，对水生生物和人类构成巨大威胁。从水环境中去除有色染料污染物是一项巨大的挑战和紧迫任务。对低成本、高效处理方法的需求不断增长，促使人们采用替代和环保的方法，如生物降解和微生物修复。这项工作总结了微生物生物吸附剂（如细菌、真菌、藻类和酵母）从水环境中修复染料污染物的概述和当前研究。此外，还强调和讨论了微生物酶的染料降解能力。还总结了各种实验参数（如温度、pH 值和营养物及染料浓度）的影响。还讨论了微生物去除染料的建议机制。本综述的目的是提供消除水资源中染料污染物的微生物修复技术的最新进展。
