Extraction and Characterization of Bioethanol as Future Fuel

Bio-ethanol has a number of advantages over conventional fuel. It comes from renewable resources that are crops. Another benefit over fossil fuels is the green house gas emission. The road transport network account for 22% of all greenhouse gas emission. But through the use of Bio-ethanol, some of these emissions will be reduced. Also blending Bioethanol with petrol will help extend the life of the diminishing oil supplies and ensure greater fuel security, avoiding heavy reliance and oil producing nation. Bioethanol is producing using familiar method, such as fermentation with the help of yeast and optimizing by several factors that influences the process for bioethanol production such as temp, pH, concentration, enzyme and raw materials. In present work the characteristics of these enzymes and important factors in enzymatic hydrolysis of the cellulose and hemicellulose to cellobiose, glucose, and other sugars are discussed. Waste flower are one of the source for production of Bioethanol it gives 42% Bioethanol with enzyme catalyzes followed by acid hydrolysis..
