Summary:Herein, zirchonium di-oxide nanoparticles (ZrO2-Nps) were selected best for cell recovery and lipid extraction for microalgae Chlorococcum sp. Optimization of ZrO2-NPs concentrations by varying time intervals was done to achieve maximum cell recovery. The flocculation efficiency of 99.59% was achieved at the elevated pH (pH 10) providing 15 mg/L of ZrO2-NPs, simultaneously 2.07 folds of increase in lipid content was observed. The extracted lipids were converted into fatty acid methyl esters (FAME) and recorded with higher amount of saturated fatty acids (SFA), and polyunsaturated fatty acids (PUFA) making it preferable for biodiesel application. The ZrO2-NPs were characterized by various analytical techniques for its application in microalgae system.
