Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.
