Most microaglae mainly use blue light (400–500 nm) and red light (600–700 nm) for photosynthesis. Therefore, spectral conversion of green light in solar radiation into red light can enhance the photosynthesis efficiency of microaglae. For this, we synthesized four perylene-based wavelength shifting dyes presenting high stability and spectral converting efficiency. Phenoxy groups were substituted at the bay position of perylene diimide to absorb the green light (500–670 nm) and emit the orange-red fluorescence light (580-700 nm). These dyes were applied in light-converting layer and light-converting medium for microalgal cultivation system. Under those cultivation system, Chlorella vulgaris cultures showed increase in lipid productivity and biomass productivity compared to the control. Overall, the cultivation results confirmed beneficial effects of modified light on microalgae cultures both on their lipid and biomass productivities. |
