摘要: Hydrolysates obtained by enzymatic saccharification of wheat straw or cornstover pretreated steam explosion in classical acidic conditions, were found non fermentable into acetone-butanol (ABE). A simple treatment involving heating the hydrolysates presence calcium magnesium compounds such as Ca(OH)2 MgCO3 at neutral pH values restored normal fermentability to these hydrolysates. The detoxification could be included standard neutralization and sterilization procedures performed before fermentation.
