For many years, wastewater engineers have known that the microbial communities in anaerobic digesters include autotrophic methanogens. These organisms live on the energy from the reaction CO2 + 4H^sub 2^ [arrow right ] CH^sub 4^ + 2H^sub 2^O, obtaining the carbon dioxide and hydrogen from other organisms that contribute other steps of the digestion process. Our profession should do more to inform the participants in national and international debates over energy policy that these microbes could be part of significant changes in the way the world stores and transports energy.
