Background: To cope up with the rapid growth of cities, automation, computation, at the
same time, the global pollution level for increasing combustion of fossil fuels to energy, the need of
hour is to find an alternative energy resource from renewable fuels.
Methods: Glucose and alcohol based biofuels were produced from pretreated mango tree wood floor
by enzymatic saccharification and fermentation. It was found that pretreatment of the biomass has a
strong effect on the quantity of the fuel produced. The fuel converted by enzymatic saccharification
was a glucose based fuel, while that by fermentation was an alcohol based fuel.
Results: The quantity of fuel produced was estimated as the amount oxygen required for its full
combustion (COD mg/l). The COD was higher for the alcoholic based fuel than the former one. Both
the fuels could be converted to pure electrical energy by electrochemical oxidation on a
electrolytically developed MnO2. The MnO2 anode was produced by electrolytic decomposition from
Conclusion: This inexpensive electrode outperformed the well known Pt electrocatalytic material and
delivered a current density in the range of 5-12 mA/cm2.
