Abstract

Naturally occurring, copper-resistant microorganisms are common in the environment. This review discusses the mechanism of copper resistance, which is not yet clearly understood, though the copper resistance conferred by a plasmid pPT23D has been elucidated at the molecular level. The different applications of copper-resistant microorganisms are described, including commerical bloleaching of copper ores. The construction of novel bioleaching strains through recombinant DNA technology may be possible. Biosorbents, the non-living microbial blomass, have been successfully used for metal recovery operations and are also reviewed.

摘要

天然存在的耐铜微生物在环境中很常见。本综述讨论了铜抗性的机制，尽管已经在分子水平上阐明了质粒 pPT23D 赋予的铜抗性，但该机制仍未完全清楚。还描述了耐铜微生物的不同应用，包括铜矿石的商业生物浸出。通过重组 DNA 技术构建新型生物浸出菌株是可能的。生物吸附剂，即无生命的微生物生物量，已成功用于金属回收操作，也进行了综述。
