ABSTRACT: This study discusses the perspectives regarding the green alga Dunaliella
salina Toed for biodiesel manufacturing purposes. The alga was cultivated
under controlled lab conditions. Biomass concentration at early stationary
grown microalga was 2.6 mg/L dry weight, while the algal oil was about
27.1% of the biomass. Algal oil was esterified and analyzed using GLC
technique. Fourteen fatty acid methyl esters were identified. The amount of
saturated and unsaturated fatty ester fractions was 35% and 65% respectively.
The physicochemical properties of fatty acids comprising biodiesel were
discussed. However, culture optimization coupled with genetic improvement will
definitely represent contributions to bring about innovation in oil
hyper-producing D. salina that will ultimately meet with success.
