Abstract

Microalgae are sustainable sources of biomass for fuel, food, and feed as well as pollutant removal from waste water. Microalgae are group of photosynthetic, heterotrophic organisms and can be cultivated under several different conditions. They are known to produce a wide range of commercially important by-products like fats, oils, sugars and are of interest for the development of the future renewable energy scenario. The lipid products from algae are suitable for the direct use as high-energy liquid fuels. The resources for growing algae to produce lipid from synthetic media are costly, therefore the derivation of cheap sources from waste is useful to cultivate algae in larger scale.
