摘要: Laccase-catalysed oxidation of the lignin-related phenol vanillyl glycol results in initial formation dimers and subsequent polymerization. The polymerization is accompanied by a liberation methanol corresponding to 15-20% demethylation. Visible spectra together with reduction experiments suggest simultaneous o-quinones. participation quinone process possible role such intermediates lignin biodegradation discussed.
