| 摘 要： | 从济南裕兴化工厂含铬废水排放口及小清河等处的污泥中分离到一株属于假单胞菌属的杆菌。该菌在厌氧条件下以Cr(Ⅵ)作为电子受体,有机物作为电子供体,具有很强的还原铬酸盐、重铬酸盐的能力。研究了该菌的生长以及还原Cr(Ⅵ)的最适条件,并以生活污水为基质进行了实际净化含铬废水的实验,发现该菌生长迅速,还原Cr(Ⅵ)速率高,生态稳定性好,可用于含铬废水的净化。

| Abstract: | A strain of bacterium belonging to the genus Pseudomonas was isolated from chromium-contaminated sediments.In anaerobic conditio.ns,it uses simple organic compounds as electron donors to reduce chromates and bichromates.Its optimal growing and Cr(VI) reducing conditions were studied.Through experiment the strain was found ro have good ecological stability and could be used in purifying chromium-contaminated industrial effluents |
