Development of a Strategy for Enhancing the Biomass Growth and Lipid Accumulation of Chlorella sp. UJ-3 Using Magnetic Fe3O4 Nanoparticles

In this study, magnetic Fe3O4 nanoparticles (NPs) were used as an effective enhancer to increase the biomass and total lipid production of Chlorella sp. UJ-3. It was found that the biomass of algal cells increased significantly when th...

UJ-3. It was found that the biomass of algal cells increased significantly when they were exposed to low concentrations of Fe<sub>3</sub>O<sub>4</sub> NPs (20 mg/L), while the best total lipid content of algal cells was achieved when they were exposed to high concentrations of Fe<sub>3</sub>O<sub>4</sub> NPs (100 mg/L). Therefore, we established a strategy to promote the growth and lipid accumulation of microalgae by initially exposing the algal cells to low concentrations of Fe<sub>3</sub>O<sub>4</sub> NPs and then treating them with an increased concentration of Fe<sub>3</sub>O<sub>4</sub> NPs after 12 days of culture. For this strategy, the biomass and total lipid production of algal cells increased by 50% and 108.7%, respectively, compared to the untreated control. The increase in lipid production and change in the fatty acid composition of Chlorella cells were found to help them to cope with the increased number of reactive oxygen species produced due to oxidative stress in alga cells after the addition of Fe<sub>3</sub>O<sub>4</sub> NPs.
