Abstract:
从江西德兴铜矿土壤中分离筛选到一株具有较强耐镉（cd）能力的细菌dx-t3-01，经生理生态及16srrna分析进行鉴定，研究其对不同浓度cd2+的耐受特性及对重金属zn2+、cu2+、ni2+的耐受性，进一步利用扫描电镜-能谱仪（sem-edx）和红外光谱（ftir）探讨菌株对cd2+累积去除的机理.经鉴定，耐镉细菌dx-t3-01为皮氏罗尔斯通氏菌（ralstoniapickettii）；cd2+最高耐受浓度（mtc）为16mmoll-1，最低抑制浓度（mic）为4mmoll-1，并可耐受一定浓度的zn2+、cu2+；菌体积累cd2+后细胞表面有沉淀物附着并有镉元素检出，对cd2+的累积主要依靠细胞壁上―po43-、胺基中的―c―n―、―m―o（o―m―o）、c=o和酰胺基（―co―nh―）基团.图5参16
