Abstract: Spatial heterogeneity of microbial populations (total heterotrophs or total bacteria (AODC), iron reducers, sulfate reducers, methanogens, aerobic, and anaerobic protozoa) and geochemical parameters (hydrocarbon concentrations, ...

Abstract: The availability of Fe(III) for microbial reduction was measured in macrocosms containing contaminated aquifer sediment with benzaldehyde as the organic substrate. Repeated benzaldehyde additions initially resulted in an ...
