ABSTRACT

 

Due to rapid depletion of fossil fuel reserves, alternative energy sources need to be renewable, sustainable, efficient, cheaper and eco-friendly. A worldwide interest in the utilization of bio-ethanol as the future transportation fuel has stimulated studies on the cost and efficiency of industrial process for ethanol production. Keeping this in view, improvements in the ethanol fermentation have been focused on the use of modified strains obtained by various methods including protoplast fusion technology to enhance the yield of ethanol production from various cheaper substrates like lignocelluloses. Ethanol is clean fuel. Its oxygen content decreases emissions when combusted with gasoline and because ethanol is derived ultimately from plant matter, its use as a fuel does not contribute to the net accumulation of carbon dioxide in the atmosphere. So, biomass and bio-energy markets are developing rapidly and pressure on available biomass resources is increasing day by day.

 

Keywords : Ethanol, Fermentation, Lignocelluloses, Gasoline, Biomass.
