Biodiesel production using marine microalgae as an alternate fuel source is receiving international attention in view of its economic and environmental advantages. The present study evaluated the feasibility of biodiesel production from the marine microalgae; Chlorella vulgaris (NIOT-74). Outdoor mass cultures of marine microalgae were done in different photobioreactors and raceways with marine C. vulgaris (NIOT- 74) as a model organism. The study demonstrated the feasibility of producing biodiesel and provided an evaluation of the physico-chemical properties of biodiesel (B100) and blend (B10) according to ASTM standards. A cost-effective electroflocculation method with 90.12% harvesting efficiency was developed and tested. The biodiesel produced from C. vulgaris (NIOT-74) was tested in two-stroke and four-stroke engines and was also used to test drive a vehicle.
