ID I, Seq. ID 2, Seq. ID 3, Seq. ID 4, Seq. ID 5 and Seq. ID 6. The present process of bio -fuel production comprises the steps of producing lipid from green algae in bioreactors by various novel steps and extracting oil from dried algal cells and ultimately producing biodiesel by transesterification of the said extracted oil.
