| 초록 | The aim of this work was to study the anisotropic effect of crystalline CaCO3nanoparticles (CN)-driven multiple refraction/scattering from the CN-coatedagglomerated cells on the rate of photosynthesis and the product yield underhigh light conditions in the freshwater microalgae Neochloris oleoabundans.The CN-coating via biomineralization significantly improved the biomass andlipid production of N. oleoabundans during second stage of autotrophicinduction by sustaining relatively high rate of photosynthesis at highirradiance using the multiple splitting effect of the anisotropic polymorphism.The CN were successfully produced, adsorbed and grown on the external cellsunder conditions of mild alkalinity (pH 7.5–8.0), mild CaCl2concentration (0.05 M) and under nitrogen starvation. Consequently, lipidcontent and productivity of N. oleoabundans cells cultured with 0.05 MCaCl2 increased by 18.4% and 31.5%, respectively, compared to the untreatedcells. |
