Iron a Key in Methane-producing Microorganisms

Penn State researchers have studied a microorganism, Methanosarcina acetivorans, and its role in decomposing dead plant material to methane and carbon dioxide. The study found the microorganism used an oxidized form of iron to work more efficiently in anaerobic conditions. Decaying rice plants are  aided in breakdown by this methanogen. By measuring the amount of iron present, predictions can be made as to how much methane will be released, which can be a tool in improving climate change models.
