Mucor circinelloides, selected from mine tailings for heavy metal bioremediation, was characterized at the genetic level by internal transcribed spacer (ITS) analysis. M. circinelloides was first applied for the absorption of heavy metals {Fe(iii), Mn(ii), Cu(ii), Zn(ii), and Pb(ii)}. The minimal inhibitory concentration test showed that M. circinelloides could tolerate relatively high concentrations of heavy metals. M. circinelloides could uptake 79.5%, 44.1%, 62.5%, 56.5%, and 85.5% of Fe(iii), Mn(ii), Cu(ii), Zn(ii), and Pb(ii), respectively, from the initial concentration of 20 mg L-1 under optimum conditions (pH 8; 30 °C). Monitoring the change in ATPase activity at certain intervals indicated that the mechanism of bioremediation was directly related to the energy consumption. M. circinelloides will be widely used for in-situ remediation in special environment because of strong vitality and excellent bioremediation efficiency.

环孢菌（Mucor circinelloides）：对重金属污染的生物修复反应效率。

通过内部转录间隔区（ITS）分析在遗传水平上鉴定了从矿山尾矿中选出的重金属生物修复中的Mucor circinelloides。Circinelloides首先应用于吸收重金属{Fe（iii），Mn（ii），Cu（ii），Zn（ii）和Pb（ii）}。最小抑菌浓度试验表明，环丙醇杆菌可耐受较高浓度的重金属。圆形螺线虫可分别从中分别吸收Fe（iii），Mn（ii），Cu（ii），Zn（ii）和Pb（ii）的79.5％，44.1％，62.5％，56.5％和85.5％。在最佳条件下（pH 8; 30°C），初始浓度为20 mg L-1。在一定的时间间隔内监测ATPase活性的变化表明，生物修复的机理与能量消耗直接相关。M.
