Abstract

Wood-grown cultures of Daldinia concentrica oxidized a permethylated [beta]-14C- labeled synthetic lignin to 14CO2 and also cleaved a permethylated [alpha]-13C-labeled synthetic lignin to give C[alpha]-C[beta] cleavage products that were detected by 13C nuclear magnetic resonance spectrometry. Therefore, this ascomycete resembles white-rot basidiomycetes in attacking the recalcitrant nonphenolic structures that predominate in lignin.
