Bioethanol is one of the most important alternative renewable energy sources that substitute the fossil fuels. Lignocellulosic substances such as agricultural wastes are attractive feedstocks for bioethanol production because agricultural wastes are cost effective and renewable. The main objective of the current study deals with the conversion of lignocellulosic waste materials such as Banana pseudostem, Bengal gram husk, coir pith, cotton pod and wheat bran into liquid based energy fuel. The experimental studies have been carried out to optimize the pretreatment process of ligncellulosic substances and efficient conversion of cellulose to sugars using the enzyme cellulose, isolated from Trametes sp. In the pretreatment process, the lignin, hemicellulose, and cellulose are separated to enhance the hydrolysis process. The cellulase was used for the hydrolysis process, which helps in converting the cellulose to sugar which was analysed using Dinitrosalicylic acid. The reducing sugars were fermented to produce bioethanol using the yeast inoculums and the yield was estimated using HPLC. Among the lignocellulosic substances used in the present study, wheat bran found to be a good producer of ethanol.
