摘　　要：The microbial reduction of ferrihydrite,lepidocrocite,hematite,goethite and aluminum-substituted iron oxides were examined by iron-reducer GS-15 under anaerobic pure culture condition.The results indicated that the ferrihydrite and lepidocrocite can be rapidly reduced by iron-reducer,and the percentage of microbial reduction are respectively 95.4% and 95.8% after 4 days incubation at 25℃.The other iron oxides like hematite,Al-hematite,goethite and Al-goethite are very difficult to reduce during short-term incubation.The amounts of Fe(Ⅲ)-reducing,Fe(Ⅱ)-producing and Fe-reducing calculated by acetate consumption are identical under the conditions of lower concentration iron oxides addition. 关键词：氧化铁铁还原菌纯培养微生物还原能力
