%X 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 25ˇăC 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, 36ˇăC 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.
