Microbial Dissimilatory Sulfur Cycle in Acid Mine Water [PDF]

open access: yesJournal of Bacteriology, 1969
Ferric, sulfate, and hydrogen ions are produced from pyritic minerals associated with coal as a result of autotrophic bacterial metabolism. Water carrying these ions accumulated behind a porous dam composed of wood dust originating at a log-cutting mill.
