Growing Scenedesmus obliquus microalgae in photobioreactor for biomass and biodiesel production

National Research Centre, Egypt
The aimof this study is to investigate the biomass andoil production capacity of S. obliquus grown inoutdoor photobioreactors
(PBR) under nitrogen repletion and starvation conditions. The volume of PBR was 4000 liters as a demo unit with the
facility of computerized controlled system. The results showed that, the maximum biomass achieved with the highest dilution
rate (0.25%) was 43.2 gm-2d-1. This was detected when the dry weight was 2.1 g/L. The maximum oil content reached to
26%±0.23 after 29 days under N repletion. However under nitrogen starvation, the oil content was dramatically increased
and reached to 41.9%±0.6 after 8 days. Fatty acids profile showed that, both saturated and unsaturated acids were detected.
The major saturated fatty acids were palmitic and stearic acids. The unsaturated fractions were detected as palmitoleic, oleic,
linoleic and linolenic acids. The fatty acids with four or more double bonds were not detected. Total saturated fatty acids
represented 60.47% and 67.43% under nitrogen repletion and nitrogen starvation respectively. The use of photobioreactor
for the production of algae is economically feasible, where there is a large amount of sun energy available, which provides a
great saving for energy. A high quality of biodiesel could be produced from microalgae S. obliquus and used efficiently and
environmentally safe in conventional diesel engine
