behind the low wall of a large former surface coal mine and then travels under-ground ca. 1 km to emerge at a borehole within the Prince Gallitzin State Forest (40°1425.25N, 78°4449.2W). This site is especially well suited for studying low-pH Fe(II) oxidation because the discharge flows undiluted by other surface * Corresponding author.
Iron-oxidizing acidophiles can overcome this kinetic barrier and promote equation 3 even under extremely acidic conditions, and thus they can play an important catalytic role in low-pH AMD treatment. Specific iron oxidation rates for acidophilic isolates range from 192 to 532 mg min −1 g protein −1 for autotrophic strains and from 191 to ...

Dec 01, 1998· Abstract. Microbial life in extremely low pH (<3) natural and man-made environments may be considerably diverse. Prokaryotic acidophiles (eubacteria and archaea) have been the focus of much of the research activity in this area, primarily because of the importance of these microorganisms in biotechnology (predominantly the commercial …
bacteria called acidophiles (e.g. Thiobacillus thiooxidans and Thiobacillus ferrooxidans). Both water and oxygen are necessary to generate acid drainage. Water serves both as a reactant and as a medium for bacteria in the oxidation process. Water also transports oxidation products. Oxygen is required as a reactant and to sustain bacteria.
