Utilization of Controlled Wastewater Nutrients for Lipid Production from Botryococcus Braunii
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Diminishing oil reserves, rising oil prices and a significant increase in atmospheric carbon dioxide levels have led to an increasing demand for alternative fuels. Microalgae have been suggested as a means for fuels production because of their advantages related to higher growth rates, higher photosynthetic efficiency and higher biomass production, compared to other terrestrial energy crops. During photosynthesis, microalgae can fix carbon dioxide from different sources, including the atmosphere, industrial exhaust gases and soluble carbonate salts. To determine the most optimal conduction for the growth of Botryococcus braunii in order in order to produce lipids that can be transformed into biodiesel fuel, different nutritional conduction were investigated. For this purpose sewage water is used as a media; and effect of nutrients viz., carbon (C), nitrogen (N), phosphorus (P) and potassium (K) etc.. on biomass growth and lipid accumulation was elucidated and the results achieved are most effective and further analyzed for biomass production chlorophyll content and lipid content. The best growth resulted in an enriched solution from the N+P media condition and the best results were obtained when medium was maintained at 16 hrs light/8 hrs darkness cycles and mechanical stirring at 120 rpm (only during the lighting hrs) with higher lipid content of 70% was observed with (C) condition.
