At first the bioreactor operated as a Rumen-like Fermenter (RF) with a Sludge Retention Time (SRT) of 7 days. The RF was subsequently transformed into an anaerobic digestion system including two configurations: continuously-stirred tank reactor and anaerobic membrane bioreactor in which different SRT values of up to 100 days were assessed. Methane production peaked at 214 mL CH4 g−1 CODIn with a SRT of 100 days. COD removal and BDP peaked at above 70% and 60%, respectively, at the highest SRT, with no pre-treatment prior to microalgae digestion. The waste sludge production dropped to 0.133 mg VSS mg−1 CODIn after a SRT of 100 days.Reserva de todos los derechosRumen microorganismsMicroalgaeAnMBRWaste sludge productionBiodegradability potentialTECNOLOGIA DEL MEDIO AMBIENTEArtículo10.1016/j.algal.2017.04.003Abierto2211-9264
