Abstract
In this study, dilute acid pretreatment of five biomass feedstocks viz., sugarcane trash, sugarcane bagasse, rice straw, corn stover and palm empty fruit bunch were compared at a given combined severity factor (CSF) range of 1.4-3.2 and were characterised using an alternative Simons' staining dye-Direct Yellow 11 fraction (DY 11, molecular weight > 100,000) to better understand the correlations of pretreatment effectiveness with biomass physicochemical properties and pretreatment conditions. Good polynomial correlations (n = 2) of CSF were obtained with hemicellulose removal, cellulose digestibility and glucose yield resulting in R-2 > 0.95. The results show that the total contents of extractives and ash have negative impacts on dilute acid pretreatment. Simons' staining results show that DY 11 can also be used to estimate cellulose accessibility to cellulase enzymes. Good linear correlations of maximum adsorption capacity of DY 11 with CSF (R-2 = 0.87-0.99) and cellulose digestibility (R-2 = 0.91-0.99) were observed for most of the pretreated biomass samples.
