Renewable biofuels are needed to displace petroleum derived transport fuels, which contribute to global warming and are of limited availability. Biodiesel and bioethanol are the two potential renewable fuels that have attracted the most attention. This study demonstrates the production of algal biodiesel from Anabaena flos–aquae. The research showed that the oil content in Anabaena flos–aquae was 40% by weight of dry biomass. Acid-catalyzed transesterification was used to convert fatty acids [FA], monoglycerides [MG], diglycerides [DG] and triglycerides [TG] to fatty acid methyl esters [FAMEs]. Gas chromatography–mass spectrometry [GC–MS] was used to analyze the FAMEs. The major fatty acid composition of the tested microalgae was a mixture of saturated and unsaturated fatty acids.
