The influence of metal oxide concentration was analysed by varying the concentration from 1.0 to 5.0% (w/v) and the treatment time was varied as 10, 20 and 30 min. The influence of mass ratio of mixed metal oxides on extraction of glycogen and lipid was analysed by varying the metal oxide ratio ranging from 0.2 to 1.0 (w/w) and the treatment time was varied as 10, 20 and 30 min. Each mixed metal oxide treated biomass was subjected to extraction process and analysis as described in previous section (Section
