[Influence factors of hydrogen production in straw fermentation].
Biohydrogen production from straw by anaerobic fermentation of digested sludge was studied. The influence of the main parameters such as particle size, the ratio of substrate to cellulase, pretreatment method and pH on the straw fermentation was investigated. With NaOH pretreatment, the rice straw with average particle size of 170 tm was fermented after hydrolyzed by cellulase with the ratio of substrate to cellulase as 1:1. And its maximal velocity and the total volume of hydrogen are respectively 0.58 mL/(h x g) and 90.5 m/g.
