OPTIMIZATION OF DILUTE ACID PRETREATMENT USING RESPONSE SURFACE METHODOLOGY FOR BIOETHANOL PRODUCTION FROM CELLULOSIC BIOMASS OF RICE POLISH

摘要: Lignocellulosic biomass is abundant and a renewable resource for the production of biofuel (bioethanol) by using fermentative organisms (Sacchromyces cervesiae & Fusarium oxysporum). Rice polish cheaper agro-waste bioethanol production. The conversion into maximum yield glucose, an important step production, requires optimum dilute acid treatment. Inhibitory compounds reduce ethanol production; therefore attempt has been made in present study to select suitable dilution Response surface methodology (RSM) design minimize effects inhibitory during sulphuric (H2SO4) dilution. treatment with H2SO4 (1.5%) at 100°C 30 minutes exhibited results. During enzymatic hydrolysis 16.52 mg/mL glucose was obtained 1 mL load 50 o C after 72 hours hydrolysis. Glucose thereafter converted 5.21g/L 3.69 g/L fermentation process Sacchromyces oxysporum respectively.
