Abstract

In this study, Cellulolyticum sp. X9, anaerobic high efficiency cellulose degrading and hydrogen producing bacterium, was isolated from a continuous-flow H₂ producing reactor(ZL92114474.1). Experimental results showed that strain X9 has high hydrogen yield (Y_H2) of 780 ml H₂/L-culture, specific H₂ production rate (Y_H2/s) of 5.1 mol H₂/g-cellulose and cellulose degradation degree of 69.6% feeding with microcrystalline cellulose (MC). Then, strain X9 was adopted to investigate H₂ production capabilities directly from corn stalks fermentation following with four different pretreatment methods. Of which, steam explosion pretreatment showed the highest H₂ yield (Y_H2) and com stalk degradation degree. This indicated that Cellulolyticum sp. X9 has great potential for fermentative H₂ production from lignocelluloses biomass like com stalks after effective pretreatment.
