Biodiesel is a fuel derives from transesterification of fats and oils. It is renewable and non-toxic ecofriendly fuel with less CO2 and NO2 emissions. Microalgae are known to contain more lipid content than macroalgae and most other oil crops. In this study, we extracted biodiesel from three microalgae Isochrysis galbana, Pavlova lutheri, Dunaliella salina and also measured the density and viscosity of biofuel obtained from these microalgae. Pavlova lutheri yielded more oil than the other two algae with biomass left over Dunaliella salina was more. The density of biodiesel obtained from these microalgae was between 0.86 g/cm3 and 0.90 g/cm3 with viscosity in the range 3.92 mm2/sec to 4.5 mm2/sec showing high density than the other oils.
