Microbial community structure evolution during the treatment of lipids-rich food wastewater in an anaerobic membrane bioreactor

This study aims to investigate the effects of lipids on the performance of AnMBR for food wastewater treatment. Oleate-Na was added to synthetic food wastewater at different concentrations (0, 2 and 4 g/L) to simulate lipids gradients. Basic water quality, biogas production, and biomass characteristics were analyzed to evaluate AnMBR performance. Bacterial and archaeal community structure in response to the addition of oleate-Na was revealed in AnMBR operation. Results from this study can provide important insights to boost AnMBR application for lipids-rich food wastewater treatment.
