Mass Cultivation of Marine Micro alga Nannochloropsis gaditana KF410818 Isolated from Visakhapatnam offshore and Fatty Acid Profile Analysis for Biodiesel Production

Economically viable algae based oil industry will depend on the high lipid content of microalgal strains. In this paper, native isolate of Nanochloropsis gaditana proved that, it is a promising strain for large scale production of biomass and biodiesel. Not all algal oils are adequate for making biodiesel, but suitable oils commonly occur. In this study, the algal growth rate, biomass production, transestrification process, lipid content and productivity of microalgae culture isolated from onshore water was determined. Furthermore, lipid extract from the isolate and its further converted to biodiesel was investigated. Results from the mass culture, 2.67 g L biomass were founded on the 10 day under indoor condition with 24 h light intensities in annular column. Maximum FAME yields 20% was observed under direct transestrification process. Fatty acid profile showed that no matter which conditions are provided for growth, but produce profitable biomass under low cost is economical. The approaches present in the study could be employed for the large scale biomass and biodiesel production.
