Abstract A novel temperature shift strategy has been proposed to overcome an inhibition on hydrogen fermentation of beverage industry wastewater (BW) due to the accumulation of propionic acid (HPr) during continuous reactor operation. The continuous performance at constant pH 5.5, temperature 37 °C and hydraulic retention time (HRT) 8 h with BW concentration of 20 g/L hexose-equivalent in a stirred tank reactor (2 L) showed an accumulation of HPr to 2.36 g/L leading to a drop in hydrogen… CONTINUE READING
