Abstract
Anaerobic digestion (AD) is a key technology for biorefinery side streams treatment. A molasses waste stream was subjected to biomethanation in a submerged anaerobic membrane bioreactor (AnMBR). An AnMBR with biogas recirculation and an AnMBR with a vibrating membrane were compared in terms of methane production and membrane fouling. Biogas recirculation seemed to be a good way to avoid membrane fouling, while a vibrating membrane was insufficient. Stable methanation (> 90% COD removal) was obtained only when diluted molasses were used, indicating an inhibiting effect of molasses. Q-PCR results revealed an increased bacteria:archaea ratio and an increased Methanosaeta:Methanosarcina ratio in both systems. The archaeal community was strongly dominated by Methanosaeta species.
