Due to rapid growth in population and industrialization, worldwide ethanol demand is increasing continuously. Microalgae have shorter growth cycle as compared to other plant; hence the algae are a very promising source of biomass for the production of biofuels and also reduce in climate change effects. Technological breakthroughs in all major aspects must be overcome before it can be a successfully large-scale and commercialized product. In the light of aforesaid issues, algae are becoming the centre of attention as an optional renewable source of biomass for production of bioethanol. They provide viable feedstock for fermentation to bioethanol production, which is grouped under ’Third generation biofuels”. Extensive research is being carried out over the last three decades there has been extensive research on algal biofuels production and the use of algae for CO2 bioremediation. Algae metabolic engineering forms the basis for 4th generation bioethanol production which can meet this need.
