| 摘 要： | 从土壤中分离筛选出几株抗Cr(Ⅵ)的硫酸盐还原菌(SRB)，能在含800mg/L Cr(Ⅵ)的培养基中生长，其中2-S-8菌株在含75mg/LCr(Ⅵ)的培养基中生长36h后，培养液中的Cr(Ⅵ)已全部消失.该菌株经初步鉴定为脱硫弧菌.试验结果表明：高毒的Cr(Ⅵ)可被SRB还原成为低毒的Cr(Ⅲ)，SRB对Cr(Ⅵ)的还原与SO42-还原作用密切相关，主要是由SRB的代谢作用所产生的还原性产物(S2-)来完成. |

| Abstract: | Several Sulfate Eir Reducing Bacteria (SRB) strains, isolated from soil, were able to grow in the medium containing 800mg/L chromium(Ⅵ), The Cr(Ⅵ) disappeared when the strain 2-S-8 grew in the medium containing 75mg/L Cr(Ⅵ) for 36h.The strain was identified as Desulfovibrio sp. The results showed that high-toxic Cr(Ⅵ) was reduced to hypo-toxic Cr(Ⅲ) by SRB, and the Cr(Ⅵ) reduction was related to the reduction of sulfate, which was mainly carried out effect by metabolin of SRB. |
