Recent advances in methane fermentation technology

In the past two decades, a number of biotechnologies for anaerobic (methanogenic) wastewater treatment have been created, and practical applications of these processes are now being extended to more recalcitrant wastewaters and to wastewaters at extreme temperatures. Our knowledge of methanogenic organic degradation associated with bioreactors is also accumulating at a rapid rate. The recent advancement of such fundamental understanding is attributed to modern molecular biology techniques applied to the study of microbial communities and to continuous challenges to the cultivation of many important but recalcitrant anaerobes in bioreactors.
