Microbial communities in anaerobic digestion processes for waste and wastewater treatment: a microbiological update.
Anaerobic digestion technology is the biological treatment of organic waste and wastewater without input of external electron acceptors (oxygen), offering the potential to reduce treatment cost and to produce energy as 'biogas' (methane) from organic waste. The technology has become enormously popular in the past two decades, and knowledge of microbiological aspects of the technology has also accumulated significantly. Major advances have been made in elucidating the diversity of yet-to-be cultured microbes in anaerobic digestion processes, and the cultivation of uncultured organisms is of great interest with regard to gaining insights into the function of these organisms. In addition, recent advances have been made in the development of microbial fuel cells as an alternative, direct energy-yielding treatment system.
