纯培养条件下不同氧化铁的微生物还原能力

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 I…
