【摘要】 硫酸盐还原菌是一类分布广泛,能进行硫酸盐异化还原反应的严格厌氧菌。利用硫酸盐还原菌可去除环境中的许多污染物,因而该类细菌在环境污染治理中具有广阔的应用前景。本文介绍了硫酸盐还原菌的生物学特性和代谢特征及其在环境污染治理中的应用,并对硫酸盐还原菌还原解毒Cr(Ⅵ)及应用于含Cr(Ⅵ)废水处理的研究进展作了综述,分析了其未来的研究方向。更多还原

【Abstract】 Sulfate-reducing bacteria (SRB) are widespread in the environment. SRB are obligate anaerobes and capable of dissimilatory reduction of sulfate. SRB have application prospects in the control of environmental pollution due to that many pollutants can be removed by SRB. The biological characteristics and metabolic mechanisms of SRB are introduced, and the application of SRB in the treatment of environmental pollution is described in this paper. The research progress of Cr(Ⅵ ) reduction and Cr(Ⅵ ) removal from wastewater by SRB is reviewed, and future direction of research on the control of Cr(Ⅵ ) pollution by SRB is also analysed.更多还原
