摘　　要：用各种木材腐朽真菌及粗酶液处理化机浆 ,检测其对提高纸浆白度和抑制纸浆热返黄的作用。其中一株黄孢原毛平革菌木素过氧化物酶缺陷株的胞外粗酶液的抑制效果最佳 ,抑制率为 2 7 9% ,与国际上同类研究水平相当。此菌株同时还有漂白纸浆和提高纸浆强度的作用 。The ability of different kinds of wood rotting fungi in increasing brightness and suppressing heat induced color reversion of CMP was studied. Among them,LIP 14,a LIP negative mutant of Phanerochaete chrysosporium which was mutated in our own lab,was the best to suppress yellowing (depression rate 27.9%). It not only can suppress color reversion of the pulp,but also can increase the brightness simultaneously. So it has more advantages than other kinds of fungi which have already been used to suppress color reversion nowadays.
