Abstract

Manganese peroxidase treatment lowered the kappa number of kraft pulp and increased the alkali extractability of the residual lignin but did not directly solubilize it. This indicates that MnP partially oxidizes the lignin in the pulp but does not degrade it to soluble fragments.

摘要

锰过氧化物酶处理降低了硫酸盐浆的卡伯值,并提高了残余木质素的碱提取率,但并未直接使其溶解。这表明锰过氧化物酶部分氧化了纸浆中的木质素,但并未将其降解为可溶性片段。
