摘要

摘要: 从四种白腐真菌中优选出最适产酶菌株黄孢原毛平革菌（〖WTBX〗Phanerochaete chrysosporium〖WTBZ〗），并对其在不同载体的附着及产酶情况进行了相关研究.试验结果表明，白腐真菌〖WTBX〗Phanerochaete chrysosporium〖WTBZ〗的锰过氧化物酶（MnP）及木质素过氧化物酶（LiP）活性最高分别可达225.67 U/L、110.35 U/L，较其它三种菌株要高；〖WTBX〗Phanerochaete chrysosporium〖WTBZ〗对尼龙纤维、厨用金刚砂尼龙、纤维海绵、玉米芯及海绵有较好的附着能力，但以厨用金刚砂尼龙、纤维海绵和玉米芯为最佳，而以玉米芯为载体所产生的MnP和LiP活性为最高，分别可达244.94 U/L和263.71 U/L，较未加载体的酶活有所提高且持续时间较长.实验优选出白腐真菌〖WTBX〗Phanerochaete chrysosporium〖WTBZ〗，且其以玉米芯为载体时所产MnP及LiP活性为最高.

Abstract: The adherence performance and enzymesproducing of four species of white rot fungi to different support materials were studied. The results indicated that the MnP and LiP of 〖WTBX〗Phanerochaete chrysosporium〖WTBZ〗 were higher than the other white rot fungi, with the maximum actirities up to 225.67 U/L, 110.35 U/L respectively. It could adhere well to the surfaces of nylon fibre, carborundum nylon, fibre sponge, corn cob and sponge. But the carriers of carborundum nylon, fibre sponge and corn cob were better than other carriers. The enzyme activity of the corn cob is higher and sustains longer. The peak activities of MnP and Lip were 244.94 U/L and 263.71 U/L, respectively.〖JP〗
