@article{(Open Science Index):https://publications.waset.org/pdf/6431, title = {Effects of Wastewater Strength and Salt Stress on Microalgal Biomass Production and Lipid Accumulation}, author = {Praepilas Dujjanutat and Pakawadee Kaewkannetra}, country = {}, institution = {}, abstract = {This work aims to investigate a potential of microalgae for utilizing industrial wastewater as a cheap nutrient for their growth and oil accumulation. Wastewater was collected from the effluent ponds of agro-industrial factories (cassava and ethanol production plants). Only 2 microalgal strains were isolated and identified as Scenedesmus quadricauda and Chlorella sp.. However, only S. quadricauda was selected to cultivate in various wastewater concentrations (10%, 20%, 40%, 60%, 80% and 100%). The highest biomass obtained at 6.6×106 and 6.27×106 cells/ml when 60% wastewater was used in flask and photo-bioreactor. The cultures gave the highest lipid content at 18.58 % and 42.86% in cases of S. quadricauda and S. obliquus. In addition, under salt stress (1.0 M NaCl), S. obliquus demonstrated the highest lipid content at 50% which was much more than the case of no NaCl adding. However, the concentration of NaCl does not affect on lipid accumulation in case of S. quadricauda.}, journal = {International Journal of Environmental and Ecological Engineering}, volume = {5}, number = {12}, year = {2011}, pages = {832 - 837}, ee = {https://publications.waset.org/pdf/6431}, url = {https://publications.waset.org/vol/60}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 60, 2011}, }
