A beneficial influence of the steam explosion pretreatment on simple sugars yield after enzymatic hydrolysis was observed. The highest average glucose content (25.8%) in the hydrolysate after steam explosion pretreatment at 190 oC was achieved. In turn, an application of steam explosion pretreatment at 205 oC resulted in a decrease of enzymatic hydrolysis efficiency and 21.8% of glucose was obtained only. In case of xylose, a similar correlations were observed. The highest average xylose content (4.0%) at 190 oC was obtained and the decrease of xylose content (to the level of 2.4%) after enzymatic hydrolysis of biomass pretreated at 205 oC was observed. Probably, the decrease of the sugars content was caused by a condensation reactions of lignin and polysaccharides. Other explanation of the obtained results may be formation of inhibitors, which could hinder enzymatic hydrolysis. This reason may be especially important, because in these studies to enzymatic hydrolysis process unwashed solid fraction was used. Obtained results were correlated to the chemical composition of the studied wood. The partial hemicelluloses degradation and dissolution led to decrease in its content and at the same time increased the content of extractives. Lignin content stayed roughly the same for both untreated material and steam explosion pretreated at 160 oC and 175 oC. However, its content increased rapidly after steam explosion pretreatment at 190 oC and 205 oC. Cellulose content was not a subject to significant changes, although its apparent increase, when compared to cellulose content in untreated wood, was probably due to decline in hemicelluloses content.
