Wheat straw and wood chips, differing in lignin composition, were treated with Lentinula edodes for 0, 2, 4, 8 and 12 wk and the changes occurring during fungal degradation were analyzed using pyrolysis-gas chromatography-mass spectrometry and detergent fiber analysis. Results L. edodes preferentially degraded lignin, with only limited cellulose degradation, in wheat straw and wood chips, leaving a substrate enriched in cellulose. Syringyl (S)-lignin units were preferentially degraded than guaiacyl (G)-lignin units, resulting in a decreased S/G ratio. A decreasing S/G ratio (wheat straw: r = −0.72, wood chips: r = −0.75) and selective lignin degradation (wheat straw: r = −0.69, wood chips: r = −0.88) were correlated with in vitro gas production (IVGP), a good indicator for rumen degradability. Conclusions L. edodes treatment increased the IVGP of wheat straw and wood chips. Effects on IVGP were similar for wheat straw and wood chips indicating that lignin content and 3D-structure of cell walls influence in vitro rumen degradability more than lignin composition. ; This study has been funded by Dutch Technology Foundation (STW), which is part of the Netherlands Organization for Scientific Research (NWO). STW did approve the experimental set up and final manuscript made by the authors. This study has also been partially funded by the Spanish projects AGL2011-25379, AGL2014-53730-R and CTQ2014-60764-JIN (co-financed by FEDER funds), the CSIC project 2014-40E-097 and the EU-project INDOX (KBBE-2013-7-613549). These parties have funded the CSIC institute and thus the analysis using Py-GC/MS ; Peer reviewed
