| Popis: | The effects of iron (Fe), zinc (Zn), and molybdenum (Mo) on the biomass yield, lipid content, lipid yield, and fatty acid composition of Chlorella sp. NC-MKM, Graesiella emersonii NC-M1, Scenedesmus acutus NC-M2, and Chlorophyta sp. NC-M5 were studied. Among them, G. emersonii NC-M1 recorded the highest percentage increase in lipid content (140.3%) and neutral lipid (50.9%) under Zn-supplemented condition compared to the control. Also, it showed a 105% and 41.88% increase in lipid yield and neutral lipid under Fe-supplemented condition compared to the control. However, Chlorella sp. NC-MKM recorded an elevation in lipid yield (70.3% rise) and neutral lipid (24.32% rise) compared to the control in Mo-supplemented condition. The enhanced production of reactive oxygen species (ROS) and antioxidant enzyme (SOD and POD) under Fe-, Zn-, and Mo-supplemented condition supports the lipid accumulation. FAME analysis showed that the overall percentage of SFA and MUFA increased after the addition of Fe, Zn, and Mo in a culture medium compared to the control which is vital for a good-quality biodiesel. Further, biodiesel properties derived from FAMEs such as CN, SV, IV, CFPP, OS, υ, ρ, and HHV were found in accordance with biodiesel standard. |
