Abstract:
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.
摘要:
来自不同行业的有色废水,例如纺织品,塑料,打印,化妆品,皮革和纸,剧毒,对水生生物和人类构成巨大威胁。从水性环境中去除有色染料污染物是一项巨大的挑战和紧迫的任务。对低成本和有效治疗方法的需求不断增长,产生了替代和生态友好的方法,如生物降解和微生物修复。本文综述了微生物生物吸附剂修复水环境中染料污染物的概况和研究现状,如细菌,真菌,藻类,和酵母。此外,微生物酶的染料降解能力已得到强调和讨论。Further,各种实验参数的影响,如温度,pH值,和营养物质的浓度,和染料,已经总结了。还讨论了微生物去除染料的拟议机理。这篇综述的目的是提供一种最先进的微生物修复技术,以消除水资源中的染料污染物。
