日本落叶松芯材用碱性亚硫酸盐蒽醌法制浆之后,用纤维素酶进行了水解处理.我们调整了蒸煮液中的Na2SO3添加率,发现以40% Na2SO3的添加率蒸煮时获得了高浆得率和最低的木素含量.蒽醌纸浆水解时,水解产物当中水解的葡萄糖量,在所有的纤维素霉添加率上,含有少量木素的纸浆高于含有大量木素的纸浆(滤纸纤维素酶单位:FPU).

Alkaline sulfite-anthraquinone (AS-AQ) cooking was applied to the pretreatment for enzymatic hydrolysis of cellulose of Japanese larch (Larix leptolepis) heartwood. We changed the ratio of Na2SO3 in the cooking liquors, and found that the 40% ratio of Na2SO3 at chips cooking had the capability of acquiring a high pulp yield and the lowest lignin content compared to others. During the hydrolysis of AS-AQ pulps, the content of glucose hydrolyzed in the enzymatic hydrolysate of a pulp containing a small amount of lignin was higher than that of a pulp containing a large amount of lignin at any cellulase charges (Filter paper cellulase unit: FPU). We determined the enzyme adsorption to the pulps by pyrolysis-gas chromatography/ mass spectrometry (Py-GC/MS).
