India is an agricultural country agricultural activity is spread over the length breath of the country. In agricultural practice main aim is to produce large quantities of various commodities of economic values. In the course to  utilized agricultural commodities sustainably, Present  study with an objective for ethanol production from six Lignocellulosic biomass viz; Sugarcane baggage, Cotton stalks, Banana stems, Wheat straws, Pigeon pea stalk, Seasame stalks has carried out using isolated Fusarium solani, Aspergillus niger, Rhizopus Microsporus and Penicillium echinulatum followed by Saccharomyces cerevisae. In primary step the degradation of agro waste was carried out using consortium of Lignocellulolytic fungi furthermore the degraded material was used as raw material for the alcohol fermentation. The results revealed   that maximum ethanol production 63.12 per cent was from Sugarcane baggage followed by Cotton stalks 32.92, Wheat straws 42.47, Banana stems 52.52 per cent and Pigeon pea stalk 14.65, respectively where as the minimum amount 8.42 per cent of alcohol was produced from Sesame stalks. In case of compound agro waste, the alcohol production was recorded 37.93 per cent. This difference in ethanol production might be due to the different concentrations of fermentable sugars in biomasses. Consequently, the results of the at hand effort clearly revealed that the cellulosic Agricultural wastes could be castoff into ethanol.
