Abstract Two continuous anaerobic fluidized bed reactors (AFBRs) were operated under thermophilic (55 °C) temperature for 150 days to investigate the effect of dark H 2 fermentation of diluted and raw sugarcane vinasse on H 2 production using mixed seed sludge. Although effective H 2 production (52.8% of H 2 ; 0.80 L H 2  h −1  L −1 ; 0.79 mmol gCOD added −1 ) was observed using an elevated substrate concentration (30,000 mg COD L −1 ), the optimal operational conditions were found for the AFBR… Expand
