Laccase-catalysed oxidation of the lignin-related phenol vanillyl glycol results in the initial formation of dimers and subsequent polymerization. The polymerization is accompanied by a liberation of methanol corresponding to 15-20% demethylation. Visible spectra together with reduction experiments suggest the simultaneous formation of o-quinones. The participation of quinone formation in the polymerization process and the possible role of such intermediates in lignin biodegradation is discussed.
漆酶催化的木质素相关酚香草基二醇的氧化导致二聚体的初步形成及随后的聚合反应。聚合反应伴随着相当于15 - 20%去甲基化的甲醇释放。可见光谱及还原实验表明同时形成了邻醌。本文讨论了醌的形成在聚合过程中的参与情况以及此类中间体在木质素生物降解中可能发挥的作用。
