Biogas with more than 98% CH4 was produced in serial upflow and bubble column reactors. Increased gas recirculation rate enhanced the biogas upgrading efficiency. Biofilm was created on top of the diffuser surface in the bubble column reactor. Abundance of novel phylotypes belonging to MBA08 and Bacteroidales sp. Methanothermobacter thermautotrophicus was the most abundant methanogen.
