Abstract
Glucose based and alcohol based biofuels were produced from pretreated mango tree wood floor by enzymatic saccharification and fermentation. Two major components of plants, starch and cellulose, are both made up of sugars, the cellulose part of a plant is broken down to sugars and subsequently converted to ethanol. The acidic or alkaline pretreatment is found to be very effective to break complex organic polymer of cellulose and hemi-cellulose into simple monomer and removing lignin which is unleachable. The quantity of fuel produced was estimated as the amount oxygen required for its full combustion (COD mg/l). The total content of glucose based fuel formed by enzymatic saccharification is found to be less than the alcoholic based fuel formed by subsequent fermentation. The fuels are converted to pure electrical energy by electrochemical oxidation on a electrolytically developed MnO2. This inexpensive electrode outperformed the well known Pt electrocatalytic material and delivered a current density in the range of 5-12 mA/cm2
