Sustainable Third Generation Microalgae Based Biodiesel Production : Challenges and Opportunities

Since from centuries humans are utterly relied on the continual use of fossil for fulfilling daily desires, however with the increasing population fossil fuels are decreasing rapidly. Fossil fuels aren't thought as sustainable source of energy. Fossil fuel are the main reason for degradation of atmosphere and increasing greenhouse gas emission. Microalgae are 3rd generation biofuel renewable source of alternative energy, and is becoming popular with the improvement in its lipid extraction method. In comparison with plants microalgae can be grown fast and improved cultivation and harvesting techniques are helpful in maintaining healthy global environment. Further, algal biomass productivities are plenty better than the ones of vascular flora and the extractable content of lipids that can be usefully transformed to biodiesel, triacylglycerol (TAGs) can be an awful lot higher than that of the oil seeds now used for first generation biodiesel. However, realistic, cost effective production of biofuels from microalgae calls for that some of obstacles be triumph over. In this paper we will be discussing microalgae as sustainable source of energy with certain challenges to overcome and future opportunities.
