Delignification of Wheat Straw by Pleurotus spp. under Mushroom-Growing Conditions.
Pleurotus sajor-caju, P. sapidus, P. cornucopiae, and P. ostreatus mushrooms were produced on unsupplemented wheat straw. The yield of mushrooms averaged 3.6% (dry-weight basis), with an average 18% straw weight loss. Lignin losses (average, 11%) were lower than cellulose (20%) and hemicellulose (50%) losses. The cellulase digestibility of the residual straw after mushroom harvest was generally lower than that of the original straw. It does not appear feasible to simultaneously produce Pleurotus mushrooms and a highly delignified residue from wheat straw.
