氰污染的微生物修复与应用

Bioremediation of Cyanide Contamination and Its Applications

由于人类活动而产生的大量氰化合物造成了土壤和水源受到严重污染,这对人类及动植物的生存构成了严重威胁,因此深入探究污染物的处理及污染环境的修复具有重要意义。生物降解具有绿色、高效、成本低等优点,成为污染处理和环境修复发展的方向。氰化合物可作为碳源和氮源被多种微生物利用,产物为低毒或无毒的物质。从氰化合物的来源、微生物降解研究现状、降解机理,影响氰化合物微生物降解的主要因素及微生物降解的应用等角度,综述氰污染微生物修复的研究进展。

The cyanide contamination of soils and water sources by anthropogenic activities caused severe threaten to lives of human,animals,and plants.So,the treatment of contaminants and remedy of environment are significantly important to environmental protection.Biological degradation may be a potentially efficient,cost-effective,environmentally friendly alternative to the previous conventional processes.Many microbial organisms can use cyanide as carbon and nitrogen source converting it into ammonia and carbonate which are less or no toxic products.This paper reviewed the research progress on the microbial remediation of cyanide contamination in terms of the major source of cyanide in soil and water,recent advances,affecting factors,the degradation mechanisms and the current applications in the microbial remediation of cyanide contamination.
