Effect of initial substrate concentrations and pH on hydrogen production from xylose with Clostridium butyricum T4
初始底物浓度及pH对丁酸梭菌T4发酵木糖产氢的影响

We studied the effect of initial pH and substrate concentrations on the conversion of xylose to hydrogen by Clostridium butyrium T4 at pH 5.0-8.5 and substrate concentrations 5?40 g/L.The cumulative hydrogen volume and the specific hydrogen production rate increased and then decreased with increasing initial pH or substrate concentrations.At initial pH 6.5 and substrate concentration 20 g/L,the cumulative hydrogen production and the specific hydrogen production rate reached the maximum value of 4.26 L/L and...
