Biodiesel from oilgae, biofixation of carbon dioxide by microalgae: A solution to pollution problems

Demirbas, Ayhan - In: Applied Energy 88 (2011) 10, pp. 3541-3547

Algae containing 30–75% of lipid by dry basis can be called oilgae. All microalgae species produce lipid however some species can contain up to 70% of their dry weight. Microalgae appear to be the only source of renewable biodiesel that is capable of meeting the global demand for transport...
