Abstract: Lignocellulosic biomass is most abundant renewable resource suitable for a continuous supply of bioethanol. Waste Jute caddies (WJC) from Jute mills can be a potential feedstock for the production of ethanol. In the present study, the effect of various pretreatments on WJC was compared by glucose and ethanol yields. The WJC was pretreated using physical and chemical pretreatments viz. steam, sodium hydroxide, sulfuric acid, Triton x-100. The cellulose fractions of pretreated WJC were allowed to undergo saccharification using cellulase enzymes. S. cerevisiae was used in the anaerobic fermentation of glucose and effect of supplementation with benzoic acid on ethanol yield was also investigated. The quantitation of glucose and ethanol was performed by High performance liquid chromatography (HPLC). The changes in chemical nature of biomass due to pretreatment were determined using XRD and FTIR. The highest yield ethanol was observed after fermentation with sodium hydroxide pretreated WJC. Based on fermentation studies conducted on WJC, the ethanol yield was enhanced up to 8% by supplementation of benzoic acid.
