摘　　要：脂环酸芽孢杆菌(Alicyclobacillus)属细菌广泛存在于酸性果汁饮料、矿山、热泉和火山附近土壤等酸热环境中,具有嗜酸耐热的典型特征。多项研究表明该属细菌具有广泛的底物利用特性,可以利用有机物进行异养生长,也可以氧化Fe2+、元素硫以及硫化矿等进行自养生长,在厌氧或微缺氧的条件下还可以还原Fe3+以及针铁矿等铁的沉淀物中的Fe?,因此该属细菌在生物冶金中具有巨大应用潜力,而目前关于该属细菌在生物冶金中的研究报道很少。对Alicyclobacillus属细菌的分离、生理生化特征以及在生物冶金领域中的国内外研究现状进行概述和分析,并展望了未来该属细菌在生物冶金领域中的研究方向。The genus Alicyclobacillus spread widely in the thermal and acidic environment such as acidic bever- ages, mines, thermal springs and solfataric soils. This kind of bacteria is characterized by endospore-formation and thermo-acidophilic nature. Several studies show that the genus Alicyclobacillus can catabolize a variety of substrates, for example, it can growheterotrophically by using organics and chemoautotrophically by oxidizing oxidize ferrous i- ron, elemental sulfur, and sulfide ore, some can also reduce ferric iron in the solution or in the precipitate such as goethite under the anoxic or microoxic condition, so the genus Alicyclobacillus has great potential for application in mineral bioleaching. Currently there are only a few reports on the extraction of metal from minerals using these bac- teria. The studies of the isolation, physiological and biochemical characteristics and separation method of the genus Alicyclobacillus and their application in biohydrometallurgy are reviewed. The application prospect of the genus Ali- cyclobacillus in biohydrometallurgy is discussed.
