Abstract:
This work involves the study of the potential production of biodiesel from green microalgae.
The green microalgae were cultured and treated with different nutrient concentrations of 0, 0.175, 0.35, 2 and 4 g in the laboratory where they were later centrifuged. he 4 g treatment had the highest growth of 0.186 cell/h, followed by the 2 g treatment of 0.151 cell/h within 24 h. he 0, 0.175 and 0.35 g had similar growth rates which were lower than the 4 and 2 g. Oil was extracted from the centrifuged cultured algae sample and the raw algae sample using hexane via Soxhlet extractor. he total oil extracted from 15 g of the centrifuged sample dry biomass and 30 g of the raw sample dry biomass were 2.038 and 3.826 g, giving a yield of 13.6 and 12.8%, respectively. he amounts of hexane recovered from the centrifuged sample and the raw sample were 46.67 and 53.33%, respectively. he results suggest hexane can be used to extract algal oil which can be transesterifed to biodiesel which is more environmentally friendly than fossil diesels
