Abstract

The effect of Trametes hirsuta laccase on isolated spruce wood lignans was evaluated. Lignans were isolated from the heartwood of spruce branches and treated with different laccase dosages and treatment times. The effect of the treatment was monitored by gas chromatography, size exclusion chromatography and ionization difference UV spectroscopy. Lignans were efficiently oxidized by T. hirsuta laccase. About half of the phenolic groups present in lignans remained intact during the treatment. The oxidation of phenolic groups in lignans produced oligomeric structures containing approximately 4–5 lignan units (i.e., 8–10 phenyl propane units). Precipitation of the formed oligomeric structures probably prevented further polymerization.
