Alternative demand is unquestionable in order to reduce gaseous emissions (fossil CO2 ,nitrogen and sulfur oxides) and their purported greenhouse, climatic changes and global warming effects, to manage the frequent oil supply crises, as a way to help non-fossil fuel producer countries to decrease energy dependence. Biodiesel from oil crops, waste cooking oil and animal fat cannot practically satisfy even a small fraction of the existing demand for transport fuels. Microalgae are a promising alternative supply of lipid for biodiesel production. This study discusses the perspectives concerning 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 1.9 mg/L dry weight, while the algal oil was about 24.8% of the biomass. Algal oil was directly transesterified and analyzed using GC/MS technique. Six fatty acid methyl esters were identified. The amount of saturated with sixteen and eighteen carbon ester fractions were38.57% .this result showed that Dunaliella salina oils were suitable for production of biodiesel.
