title: Fungal pretreatment improves amenability of lignocellulosic material for its saccharification to sugars.
abstract: The sugarcane bagasse was biologically pretreated with three white-rot fungi; Pleurotus florida, Coriolopsis caperata RCK 2011 and Ganoderma sp. rckk-02, individually under solid-state fermentation. P. florida, C. caperata RCK 2011 and Ganoderma sp. rckk-02 degraded lignin up to 7.91, 5.48 and 5.58%, respectively. The lignocellulolytic enzymes produced by these fungi were also monitored during solid state fermentation of sugarcane bagasse. The fungal fermented sugarcane bagasse when hydrolyzed with crude cellulases from brown-rot fungus, Fomitopsis sp. RCK2010, released comparatively 1.5-2.4 fold higher sugars than in case of untreated sugarcane bagasse. The study demonstrated that white-rot fungal pretreatment improved the amenability of plant material for enzymatic hydrolysis.
