Comparative Study on Quality of Fuel Pellets from Switchgrass Treated with Different White-Rot Fungi

Fungal pretreatment of switchgrass using Phanerochaete chrysosporium (PC), Trametes versicolor 52J (TV52J), and the Trametes versicolor mutant strain (m4D) under solid-state fermentation was conducted to improve its pellet quality. For all thr...
