This reference site explains the role of microbes in acid rock drainage. Topics include the sulfur cycle, the role of microorganisms in the sulfur cycle, natural oxidation in the sulfur cycle, natural reduction in the sulfur cycle, other microorganism reactions in the sulfur cycle, and references. The reference includes a scientific illustration of the sulfur cycle, images of sulfur-oxidizing microbes, and graphs representing the effects of bacteria on the system. The site is part of a large module about acid rock drainage: http://technology.infomine.com/enviromine/ard/home.htm.
