Abstract

A bacterial strain, Pseudomonas putida S4, was isolated from smelter drainage of copper mines. The strain exhibited resistance to several heavy metals, like aluminium (Al), zinc (Zn), nickel (Ni), cobalt (Co) besides copper (Cu). Strain S4 could accumulate Cu from the Cu-supplemented growth medium. In the present study, we have demonstrated the Cu2+ removal capacity of this strain from various samples such as mine effluent, low-grade ore and ore-tailings, collected from the mining site. Moreover, approximately 80% of the accumulated Cu2+ could be recovered from the loaded biomass by a simple desorption procedure.

摘要

从铜矿冶炼排水中分离出一株细菌，恶臭假单胞菌S4。该菌株除了对铜（Cu）具有抗性外，还对几种重金属具有抗性，如铝（Al）、锌（Zn）、镍（Ni）、钴（Co）。菌株S4可以从添加铜的生长培养基中积累铜。在本研究中，我们已经证明了该菌株从采矿业现场采集的各种样品（如矿山废水、低品位矿石和尾矿）中去除Cu2+的能力。此外，通过简单的解吸程序，可以从负载的生物质中回收约80%积累的Cu2+。
