三苯甲烷类染料脱色细菌降解途径及其机制研究进展

三苯甲烷类染料被广泛应用于纺织、医药、食品等行业,但染料废水中含有大量环境难以降解的有害物质,这些物质会随着染料废水不断地排放而在环境中积累,最终危及到人类的生存.目前对于染料的处理主要采用成本高、且会产生二次污染的物理、化学方法.生物降解染料因具有环境友好的特点而越来越受到重视.作者主要从细菌降解三苯甲烷类染料的角度,对目前已报道的主要脱色菌种,以及涉及到的相关代谢产物、降解途径,相关脱色机理等方面进行综述,并对其未来发展前景进行展望.

Process of the pathways and mechanisms of triphenylmethane dyess biodegradation by bacteria

Triphenylmethane dyes have been extensively used in the textile,medicine and food industries,while the wastewater produced contains large amounts of harmful substances which accumulate in the environment by continuous discharge and result in a great threat to human health.To decontaminate the wastewater,physico-chemical methods are used currently,which are expensive and cause secondary pollution,so more and more attention has been paid on the biological degradation with environment-friendly characters on the dyes.This paper is on the angle of the bacterial degradation on triphenylmethane dyes,the main reported decolorization bacteria,as well as related metabolites,pathways and biodegradation mechanisms are reviewed.What's more,the development of the biodegradation on triphenylmethane dyes in the future is also prospected.
