From: Pre-concentration of microalga Euglena gracilis by alkalescent pH treatment and flocculation mechanism of Ca3(PO4)2, Mg3(PO4)2, and derivatives

Fig. 8

FE of E. gracilis was determined at pH 8.5 with different concentrations of Ca2+ and Mg2+. FE, flocculation efficiency. Control represents fresh PEM medium without Ca2+ and Mg2+. NS, ** represent p > 0.05, p < 0.01, respectively. The values represent mean ± S.D. n = 3
