Improving ruminal digestibility of various wheat straw types by white-rot fungi.

ABSTRACT:

Background

This study investigated the ruminal degradability of various wheat straw types by the white-rot fungi Ceriporiopsis subvermispora (CS) and Lentinula edodes (LE). Different cultivars (CV) of wheat straw at different maturity stages (MS) were treated with the fungi for 7 weeks and assessed for chemical composition and in vitro gas production (IVGP).

Results

Both fungi showed a more pronounced degradation of lignin on a more mature straw (MS3; 89.0%) in comparison with the straw harvested at an earlier stage (MS1; 70.7%). Quantitative pyrolysis coupled to gas chromatography and mass spectrometry, using ¹³ C lignin as an internal standard ¹³ C-IS Py-GC/MS revealed that lignin in more mature straw was degraded and modified to a greater extent.
