â¢The power-to-gas process provides new possibilities for biogas industry.â¢Bio-methane can be a platform chemical for various biorefinery products.â¢Bio-methane is a dangerous GHG emission source if not controlled properly.â¢There are numerous routes to control bio-methane emission, better ones are needed.
Results in three areas of anaerobic microbiology in which methane formation and utilization plays central part are reviewed. a.) Bio-methane formation by reduction of carbon dioxide in the power-to-gas process and the various possibilities of improvement of the process is a very intensively studied topic recently. From the numerous potential methods of exploiting methane of biological origin two aspects are discussed in detail. b.) Methane can serve as a platform chemical in various chemical and biochemical synthetic processes. Particular emphasis is put on the biochemical conversion pathways involving methanotrophs and their methane monooxygenase-catalyzed reactions leading to various small molecules and polymeric materials such as extracellular polysaccharides, polyhydroxyalkanoates and proteins. c.) The third area covered concerns methane-consuming reactions and methane emission mitigation. These investigations comprise the anaerobic microbiology of ruminants and approaches to diminishing methane emissions from ruminant animals.
