The emission of methane (1.3 mmol of CH(4) m(-2) day(-1)), precursors of methanogenesis, and the methanogenic microorganisms of acidic bog peat (pH 4.4) from a moderately reduced forest site were… (More)
Low-sulfate, acidic (approximately pH 4) fens in the Lehstenbach catchment in the Fichtelgebirge mountains in Germany are unusual habitats for sulfate-reducing prokaryotes (SRPs) that have been… (More)
To evaluate the microbial populations involved in the reduction of Fe(III) in an acidic, iron-rich sediment, the anaerobic flow of supplemental carbon and reductant was evaluated in sediment… (More)
A strictly anaerobic, H2-utilizing bacterium, strain SL1, was isolated from the sediment of an acidic coal mine pond. Cells of strain SL1 were sporulating, motile, long rods with a multilayer cell… (More)

Using a combination of cultivation-dependent and -independent methods, this study aimed to elucidate the diversity of microorganisms involved in iron cycling and to resolve their in situ functional… (More)
Acetogens reduce CO2 to acetate via the acetyl-CoA pathway and have been classically thought of as obligately anaerobic bacteria. Nearly 100 acetogenic species from 20 different genera have been… (More)
Peatlands are sources of relevant greenhouse gases such as CH4, but the temporal presence of Fe(III) may inhibit methanogenesis. Because excess of carbon during the vegetation period might allow… (More)
The combination of low pH and high concentrations of nitrate and radionuclides in the subsurface is representative of many sites within the U.S. nuclear weapons complex managed by the Department of… (More)
The dissimilatory reduction of sulfate contributes to the retention of sulfur in acidic mineratrophic peatlands. Novel sulfate-reducing prokaryotes (SRPs) colonize these low-sulfate fens. This study… (More)
