Biotransformation of aspen lignin by the fungus trametes villosus

摘要

Quantitative ~1H and ~(13)C NMR spectroscopies demonstrate that biotransformation of aspen wood by the fungus Trametes villosus results in oxidation and destruction of lignin with cleavage of C-C alkyl-alkyl bonds in side chains and partial demethoxylation in addition to cleavage of lingnocarbohydrate bonds. New C_(ar)-O-C bonds form while lignin is being destroyed at alkyl-alkyl bonds. Cleavage of rings and destruction of C_(ar)-C bonds was not observed.
