Abstract

Eighty-three strains belonging to three species of the genus Trametes FR. (T. versicolor, T. hirsuta and T. ochracea) collected in different localities and on different substrates were screened for laccase production. The production of other lignin-modifying enzymes--manganese peroxidase (MnP) and lignin peroxidase (LiP)--and the decolorization ability were also determined in 21 of them. Production variability was relatively high and no significant correlation was found between the origin of the strains (locality, substrate) and the enzyme production. Dikaryons of all 3 species (but not of all their strains) exhibited LiP activity, which was not detected in the respective monokaryons.

摘要

对采自不同地点、不同基质的属于栓菌属（FR.）三个物种（云芝、毛栓菌和赭黄栓菌）的83个菌株进行了漆酶产生的筛选。还对其中21个菌株测定了其他木质素修饰酶——锰过氧化物酶（MnP）和木质素过氧化物酶（LiP）的产生情况以及脱色能力。产量变异性相对较高，且未发现菌株来源（地点、基质）与酶产量之间存在显著相关性。所有3个物种的双核体（但并非其所有菌株）均表现出LiP活性，而在相应的单核体中未检测到该活性。
