A Study on High Yield Astaxanthin Production by Haematococcus pluvialis under Various Light Intensities and Different Wavelengths

초록

Factors for high-density Haematococcus pluvialis cultures and conditions of astaxanthin induction were examined to maximize astaxanthin production. Light intensity was the most important factor and thus experiments were carried out using different light sources with various light intensities. A high cell density of over 2.7 g/L was obtained under 60 mE/m2/s or higher intensities. The maximum astaxanthin concentration of 6.5 mg/L was obtained at the light intensity of 160 mE/m2/s. The supplement of 470 nm photons enhanced carotenoid and chlorophyll formation.
