Biodiesel is an excellent substitute for conventional diesel fuel
because of being renewable, nontoxic and biodegradable. It consists
of mono-alkyl esters usually produced from renewable feedstocks
(Demirbas, 2009). At present, the high cost of biodiesel is
the major obstacle for its commercialization. Approximately 70–
95% of the total cost of biodiesel production is attributed to raw
feedstocks (Leung and Guo, 2006; De la Hoz Siegler et al., 2011).
The availability of the oil crops serve as the sources for the biodiesel
production are limited (Chisti, 2008). Macroalgae are a potential
alternative source for the conventional feedstocks (Ross et al.,
2008) and algal oil is suitable for esterification/transesterification
reaction of biodiesel production. The recent renewable source of
algal oil that could meet the global demand for transport fuels.
