Abstract: The present work investigates the potential of Java citronella lignocellulosic residual biomass for efficient bioethanol production. The study focuses on the physicochemical analysis of Java citronella to explore the % of cellulose, hemicelluloses, lignin, calorific value, ash contents, carbon-hydrogen-nitrogen-sulphur (CHNS) analysis and X-ray diffraction (XRD). After the physicochemical analysis, the samples were subjected to subsequent acid and alkaline pretreatment along with 3,5-dinitrosalicylic acid (DNS) test followed by submerged biological fermentation using commercial yeast. The fermented samples were then distilled, and the distillate was examined by gas chromatography (GC), and the percentage of bioethanol was estimated. The result highlights that the collected Java citronella sample has considerable % cellulose content and alkaline pretreatment was more effective than acid treatment. In conclusion, Java citronella residual biomass has a potential for bioethanol production leading to sustainable energy options.
