Abstract: Petroleum products are running out of race due to unbalanced relation between demand and supply besides air pollution. Bio ethanol is alcohol made by fermentation and the same can be used as a fuel for vehicles in its pure form. Lignin portion of the plant raw materials can be converted into fuel components by fermentation. Saccharomyces cerevisiae is the most useful yeast having been used in the fermentation process. Agricultural wastes have been used for the bio ethanol production after lignin degradation using Saccharomyces cerevisiae. Orange peel, and agricultural wastes like vegetable peel offs weeds (Parthenium) were used as substrates. A pH of 5- 5.5 was maintained in all samples to have the optimum growth of microorganisms. The maximum concentration of was found to be 34% in orange peel, 32% in Pine apple and 39% in agricultural wastes. At a pH of 5-5.5, the optimised conditions of sugar molasses are of temperatures 35 degree celcius and Time 72 hours which gave maximum ethanol yield of 39%. The strength and persistence of bio ethanol development is contingent on successfully addressing a number of challenges. Challenges include increasing ethanol use in current markets and expanding its use in new markets; increasing production relative to cost; developing the use of feedstocks and optimizing the environmental benefits of ethanol in comparison to the use of petroleum products.
