Over the past few decades, microalgal biomass has been considered as a promising biodiesel resource due to its several advantages, such as; 1) higher growth rate and oil accumulation than terrestrial plants along with higher atmospheric carbon dioxide scavenging, 2) no food deficiency compared to 1st generation food crop-based biodiesel, and 3) no requirement of arable land for cultivation [1]. Under certain conditions, microalgae can accumulate large amounts of fatty acids which can be converted into biodiesel. In this study, magnesium aminoclay (MgAC) nanoparticles were added to oleaginous microalga Chlorella sp. KR-1 cultures at various concentrations to enhance lipid productivity. The maximum biomass production (3.19 g/L) and FAME (Fatty acid methyl esters) content (381.95 mg/g cell) were recorded when 0.5 g/L MgAC applied to Chlorella sp. KR-1 cultures. Also, higher FAME productivity of ~ 174.05 mg/L/d could be obtained at 0.5 g/L MgAC concentration. |
