摘要: Hydrogen was produced by simultaneous saccharification and fermentation from steam-exploded corn straw (SECS) using Clostridium butyricum AS 1.209. Effect of various process parameters, such as solid to liquid ratio, enzyme loading initial pH, etc., were examined with respect maximum hydrogen productivity which obtained fitting the cumulative production data a modified Gompertz equation. Maximum specific rate maximal yield 126 ml/g VSS d 68 SECS, respectively. The soluble metabolites 197.7 mg/g SECS. Acetic acid accounted for 46% total most abundant product this shows that SECS essentially acetate-type fermentation. has predominance short lag-stage high it promising method biomass conversion.
