Biodiesel comparable to conventional diesel was obtained from heterotrophic microalgal oil by acidic transesterification. The best process combination was 100% catalyst quantity (based on oil weight) with 56:1 molar ratio of methanol to oil at temperature of 30 degrees C, which reduced product specific gravity from an initial value of 0.912 to a final value of 0.8637 in about 4h of reaction time.

The microalgal BD production cost is also higher than that of fossil diesel [4,26]. According to Chung et al. [27], to cost-effectively produce BD from microalgae, the availability of mi-croalgal biomass, synthetic extraction procedure, and production of high-quality microalgal BD must be considered.
