The ability of Pleurotus cornucopiae var. citrinopileatus Pc82-1 (P. cornucopiae 82-1) to improve in vitro degradability of wheat straw was evaluated. P. cornucopiae Pc82-1 was incubated on wheat straw substrate with or without rice bran (10, 30, and 50% on dry matter basis) for 15-90 days. The acid detergent fiber, acid detergent lignin and dry matter degradability by cellulase were determined. The dry matter content, acid detergent lignin and hemicellulose in the wheat straw substrate decreased remarkably by incubation with P. cornucopiae Pc82-1. The dry matter degradability by cellulase of the wheat straw substrate increased to 55% and the degradable dry matter increased to 189% of its initial weight after 45-day incubation with P. cornucopiae Pc82-1. However, addition of rice bran did not improve the substrate degradability.
