摘　　要：研究了泡桐（Ｐａｕｌｏｗｎｉａｅｌｏｎｇａｔｅ）木片用三种真菌（ＰｈａｎｅｒｏｃｈａｅｔｅｃｈｒｙｓｏｓｐｏｒｉｕｍＭＥ４４６及其变异株ＬＩＰ１４和商品菌Ｏｐｈｉｓｔｏｍａｐｉｌｉｆｅｒｕｍ）预处理制生物机械浆。测定了预处理对木片主要化学组成、磨浆能耗、纸浆强度的影响。结果表明：（１）ＬＩＰ１４及ＭＥ４４６预处理后，木片失重４３１％～５４２％，其中１９６％～２１６％为木质素损失；Ｏ．Ｐ．菌预处理后，木片热水抽出物降低了３３１％，苯醇抽出物减少１２１％；（２）磨浆度５５°ＳＲ，三种菌可节省能耗１３２％～２２４％，裂断长提高７９％～３０％，耐破度提高１５２％～８８％，撕裂度提高３８％～１２％，白度下降３％～４％ＩＳＯ，光散射系数下降１００％～１４６％，不透明度变化不大。综合能耗节省与强度性质的提高，ＬＩＰ１４优于Ｏ．Ｐ．菌，Ｏ．Ｐ．菌优于ＭＥ４４６。This paper deals with the pretreatment of Paulownia elongate wood chips with three strains of fungi (Phanerochaete chrysosporium ME446 and its mutant LIP14, and a commercial fungus Ophistoma piliferum) and the effects of fungal pretreatment on the chemical composition of chips, refining energy consumption and pulp strength. The results showed:(1) After pretreatment with LIP14 and ME446, the chip weight loss was 4.31%～5.42% and 19.6%～21.6% of which was lignin loss. For chips treated with O.P., hot water extractives and benzenealcohol extractives were reduced 33.1% and 12.1%, respectively. (2)Three fungal treatments at 55°SR beating degree saved 13.2%～22.4% energy with 7.9%～30%, 15.2%～88% and 3.8%～12% increases in break, burst and tear indexes, respectively. However, the brightness and light scattering coefficient were reduced 3%～4% ISO and 10%～14.6% respectively, with little effect on opacity. Based on the results of both energy savings and strength property improvement, LIP14 was the most promise fungus for use in biomechanical pulping of Paulownia elongate chips, while O.P. ranked the second and ME446 the last.
