Enhancement of FAME Productivity of Scenedesmus obliquus by Combining Nitrogen Deficiency with Sufficient Phosphorus Supply in Heterotrophic Cultivation
Researchers from China conducted an experiment to enhance FAME productivity of Scenedesmus obliquus by combining nitrogen deficiency with sufficient phosphorus supply in heterotrophic cultivation. Scenedesmus obliquus NIES-2280 was cultivated heterotrophically in a nitrogen deficient and phosphorus rich medium. Acetate was used as a carbon source.
Results showed that the productivity of fatty acid methyl esters increased fourfold under nitrogen deficient conditions. Thus the study could be a great potential to use S. obliquus for combined wastewater treatment and biodiesel production thereby improving biodiesel productivity and COD utilization under nitrogen deficient and phosphorus rich medium.
