Bio-Oil Production Potential of Microalgae
Fossil fuels as energy source raised global warming concerns. Contrary to this, Conventional biofuels (first and second generation fuels) have raised concerns related to cost effectiveness and food security. Algae-based biofuels (Third generation fuels) gains popularity as a sustainable bioenergy source. Microalgae offer the dual advantage of a natural bioremediation agent and a source of biofuel. Commonly used microalgal species for wastewater treatment includes Chlorella, Scenedesmus, Gloeocapsa, Anabaena, Oscillatoria, etc., . In bioremediation process, wastewater acts as a nutrient medium for microalgal growth and in return microalgae treat wastewater can be reused for various purposes based on the post-treatments applied. In this way, microalgal biomass can be produced from wastewater at no more additional cost, thus serves as a sustainable and economically viable source for bioenergy production.
