Abstract

Ultrafine calcite particle production by coccolithophorid algae using a biosolar reactor system was carried out. Solar light was collected by Fresnel lenses and transmitted to a bundle of light diffusing optical fibers (LDOFs) that distributed light through the algal culture. The irradiance spectrum of light emitted from the LDOF surface was the same as that of solar light. Emiliania huxleyi was cultured for 8 d, and 43 mg/L of calcite were produced. These results demonstrate the potential of the biosolar reactor system for CO2 fixation, and ultrafine calcite particle production using coccolithophorid algae and sunlight.
