Fungal pretreatment of sweet sorghum bagasse (SSB) by solid state fermentation (SSF) studied in a Mesh tray bioreactor. In pretreatment by using Coriolus versicolor, optimal mesh size in tray and humid airflow into bioreactor overcame the problems of SSF and improved fungal growth; increased the production of lignolytic enzymes laccase, lignin peroxidase, manganese peroxidase, polyphenol peroxidase, aryl alcohol oxidase by 1.9, 1.85, 2.6, 2.0, 1.9 folds respectively; hemicellulolytic enzyme xylanase by 1.8 folds and decreased cellulolytic enzymes production. Altered lignocellulolytic enzyme profiles resulted in high lignin degradation 46.092.0%ww(-1), high selectivity value 5.98 and low cellulose loss 7.7 +/- 0.3%ww(-1). Enzymatic hydrolysis of pretreated SSB yielded higher (2.47 times) fermentable sugar. Characterizations of SSB by SEM, XRD, FTIR, TGA/DTG supported the results. Mesh tray bioreactor could be used for fungal pretreatment and enzyme productions by SSF of waste biomass. [GRAPHICS] .
