Abstract: A membrane biofilm reactor including a vessel defining a volume is disclosed. The reactor also typically includes a first and second plurality of hollow fiber membranes. Each hollow fiber membrane generally has an outer surface and a lumen, and is located within the volume. The reactor further preferably includes a first and second gas feedstock. The first gas feedstock is provided through a first inlet in fluid communication with the lumens of the first plurality of hollow fiber membranes. The second gas feedstock is provided through a second inlet in fluid communication with the lumens of the second plurality hollow fiber membranes. Finally, the reactor also typically includes a biofilm formed on the outer surface of the hollow fiber membranes and made up of methanotrophs, Methanosarcina acetivorans, or both. The first gas feedstock is preferably different from the second gas feedstock.
