It was ground with grinding machine, and dried for 20 min. at 80o C in an incubator for releasing water. Oils were obtained by extracting the algae with hexane in a Soxhlet extractor for 18 h . Biomass obtained after filtration. Solvent from extracted oils was separated using rotary evaporator. For transesterification reaction methanol was mixed with a catalyst (NaOH) and stirred properly for 20 mins. The mixture of catalyst and methanol was poured into the algal oil in a conical flask. Alkali- catalyzed transesterification carried out at approximately 60o C under atmospheric pressure.
