PRODUCTION OF BIO ETHANOL BY ENZYMATIC HYDROLYSIS & FERMENTATION FROM ALGAL BIOMASS

Because of rapid growth in population and industrialization, worldwide ethanol demand is increasing continuously. The first-generation and second-generation biofuels are unable to meet the global demand of bioethanol production because of their primary value of food and feed. Therefore, algae are among the most potentially significant sources of sustainable. biofuels in the future of renewable energy because of the accumulating high starch/cellulose and because they are widely distributed in nature. Bioethanol is more environment friendly because it is renewable energy source, and it is considered as one of the most promising replacements of gasoline to act as a transport fuel.Despite the many developments made in the recent years, commercialization of algal bioethanol remains challenging chiefly because of the techno-economic constraints
