Media and pH are two crucial factors in microalgal cultivation. Industrial wastewater such as tofu can be utilized alternative media for growing microalgae like Euglena sp. to produce biomass feedstock biorefinery activities. Here, we evaluated combinations of (L) consisting 0% (L1), 75% (L2), 100% (L3) with (P) levels 5.0 (P1), 5.5 (P2), 6.0 (P3), 6.5 (P4), 7.0 (P5). The analyses were carried out on the growth kinetics, biomass, primary metabolite compounds, pigments Based study, highest cell density, maximum carbohydrate content, lipid protein content L2P2 (23.13x105 cells/ml), L2P1 (4.53±0.17 mg/ml), L1P5 (0.93±0.02 (1.27±0.11 L3P4 (256±26.86 ppm), respectively. Moreover, chlorophyll-a, chlorophyll-b, carotenoid L2P4 (33.53±0.13 mg/l), (17.73±0.50 (11.65±0.00 addition combined specific level enhanced composition (P<0.05), exception content. Additionally, each biochemical component had a different optimum combination level. However, this potentially used an medium cultivating microalga order cut production costs activity.
