Paper Title:
Effect of Biogas Production Characteristics of Dry Anaerobic Fermentation of Wheat Straw Pretreated by a Microbial Community with High Cellulose-Degradation Ability
  Abstract

The study on the changes of composition and content reducing sugar of wheat straw after pretreated with composite microbial system for degrading cellulose was carried out, and the experimental study on the dry anaerobic fermentation of the pretreated wheat straw was followed. The results showed for pretreated wheat straw there is a significant increase for the amount of reducing sugar, the hemicellulose content decreased 49.43%, the cellulose content also decreased a little, but the lignin content had little change. For the dry anaerobic fermentation process, the reaction is started fast, the pH values declined faster in the prophase for the pretreated straw, the mixed biogas production and the methane content have been increased over that of non-pretreated wheat straw, and the gas was produced more steadily. The accumulated gas production had been to 4810mL, which was more than the non pretreated straw, before the maximum gas production was appeared.
