Iron-sulfur oxidizing bacteria in coal refuse and reclaimed prime farmland
Many acres in Illinois have been seriously disrupted by surface-mine wastes, and acid drainage via surface and groundwaters from overburden spoil banks has been a major source of perturbation to streams and vegetative and wildlife communities. The restoration of mined farmland may be hindered by the generation of acidity by the iron-sulfur bacteria. This generation is the result of chemical and microbiological activities. An assessment of Thiobacillus ferrooxidans needs to be made in Illinois soils. The iron comes from the waste pyrite being oxidized to produce H/sub 2/SO/sub 4/. Then the iron can be regenerated and reoxidized by T. ferrooxidans. The seasonal variation of the thiobacilli has been analyzed. Data indicates that the thiobacilli population is very active and an inhibitor needs to be found, one which can help control biologically produced acidity and so enhance reclamation efforts in mine-disturbed lands. 1 table.
