Effect of changing medium ingredients on pigment and biomass yield. Medium 1 consists of 50% whey and 0.5% yeast extract. Medium 2: 1% NH4Cl added to medium1, Medium 3: 1% KH2PO4 added to medium1, Medium 4: 1%MgSO4 added to medium 1, Medium 5: 50% Sweet. All trials were carried out in triplicates at 20 °C. The significant difference was considered according to the overlapping rule at P-value ≤ 0.05. (Cuming et al. 2007)
