Abstract: Cellulose-hydrogen production from corn stalk by lesser panda manure was carried out in batch tests and a 5 L scale-up continuously stirred anaerobic bioreactor (CSABR), respectively. The bio-pretreatment of corn stalk was found most effective at 25°C using microbe additive of 7.5 g/kg, in which the yields of soluble saccharides (SS) and lactic acid were 212 mg/g-TS and 21 mg/g-TS, respectively. The maximum cumulative H2 yield (176 ml/g-TS) and H2 production rate (14.5 ml/g-TS h−1) were obtained at pH 5.5, 36°C by treating a substrate of 15 g/L. The hydrogen content in biogas was 57.2% and there was no significant methane gas observed. During the optimal period of H2 production, the ORP values stayed in the lower level ranging from −445 mV to −455 mV. The results show that the bio-pretreatment of the raw materials played a vital role in the effective conversion of corn stalk into cellulose.hydrogen by mixed culture.
