A hydrogen-oxidizing, Fe(III)-reducing microorganism from the Great Bay Estuary, New Hampshire
Article Abstract:
Core samples of near shore sediment collected from Great Bay, NH, were subjected to enrichment conditions for the isolation of Fe(III)-reducing microorganisms. An isolated colony was further characterized. The results showed that the isolated organism could oxidize molecular hydrogen in the presence of a carbon source. Other physiological characteristics suggest that the organism is similar to H2-oxidizing, Fe(III)-reducing Pseudomonas sp.. However, its G + C content and cellular fatty acid analysis are not consistent with this. Therefore, a temporary designation of BrY is proposed.

Dissimilatory Fe(III) reduction by the marine microorganism Desulfuromonas acetoxidans
Article Abstract:
The reduction of Fe(III) by the marine microorganism Desulfuromonas acetoxidans was investigated. Cell suspensios from the strain were sujected to centrifugation and suspension experiments. Cytochrome oxidaton studies and growth experiments with acetate were also conducted. Acetate concentrations were determined by high pressure liquid chromatography. The metabolic capabilities of the microorganisms for growth involving acetate oxidation to Fe(III) reduction were demonstrated.

Isolation of Geobacter species from diverse sedimentary environments
Article Abstract:
Fe(III) reducers are isolated from freshwater aquatic sediments and the Fe(III) reduction zones of a deep pristine aquifer and a shallow petroleum-contaminated aquifer to identify the organisms that cause oxidation of organic compounds in Fe(III)-reducing environments. Results show that the organisms responsible for the oxidation phenomenon belong to the genus Geobacter in the delta subdivision of Proteobacteria.
