摘要：

The characterization of the residual lignins in Pinus taeda biodegraded by ceriporiopsis subvermispora, was discussed using in situ CuO oxidation and derivation followed by reductive cleavage (DFRC). It was found that an extensive depolymerization of the lignin occurred before its mineralization became significant. The analysis showed that the residual lignin in Ceriporioposis subvermispora-dacayed samples was enriched in carbon-carbon substructures.
