我们从制革废水中分离和鉴定了一株新的科氏葡萄球菌，并研究了该菌对铬的生物积累能力。科氏葡萄球菌对铬具有抗性，在添加1000ppm铬(VI)的标准培养基中生长良好。在96小时的处理周期内，该菌株从含100ppm铬(VI)的培养基和受污染的制革废水中去除了约90%的铬(VI)。原子吸收法证实了废水中铬的生物积累。结果进一步表明，该有机体将六价铬还原为三价铬。
We have isolated and identified of a new isolate of Staphylococcus cohnii from a tannery effluent and have studied the capacity of the organism to bioaccumulate chromium. The Staph.cohnii isolate is resistant to Cr, growing well in standard medium supplemented with 1000ppm Cr(VI). Over a treatment period of 96 hrs, the isolate removed about 90% Cr(VI) from medium containing 100ppm Cr(VI) and from contaminated tannery wastewater. Bioaccumulation of Cr from the wastewater was confirmed by atomic absorption. Results further indicate that the organism reduces Cr(VI) to Cr(III).
