Three phenolic model compounds representing bonding patterns of residual kraft lignin were incubated with manganese peroxidase from Lentinula edodes. Extensive degradation of all the phenolic models, mainly occurring via side-chain benzylic oxidation, was observed. Among the tested model compounds the diphenylmethane alpha-5 phenolic model was found to be the most reactive, yielding several products showing oxidation and fragmentation at the bridging position. The non-phenolic 5-5' biphenyl and 5-5' diphenylmethane models were found unreactive.
将三种代表残余硫酸盐木质素键合模式的酚类模型化合物与香菇的锰过氧化物酶一起孵育。观察到所有酚类模型都有广泛的降解，主要通过侧链苄基氧化发生。在测试的模型化合物中，二苯基甲烷α-5酚类模型被发现反应性最强，产生了几种在桥接位置显示氧化和断裂的产物。发现非酚类的5-5'联苯和5-5'二苯基甲烷模型无反应性。
