The microalgae have a photosynthetic apparatus that can conduct photosynthesis produce various by-products by metabolic pathway and expect reduction of Carbon dioxide concentration. Among microalgae species, Haematococcus pluvialis is a microalgae species that produces High-Value products called Astaxanthin. In this research, a polymer film type photobioreactor was used to cultivate H. pluvialis in indoor and outdoor conditions and to increase productivity at the limit of small scale. The cultivation condition was 20~25℃, with the light intensity of 0~300 μmol photon/m2 s and 25L polymer film type photobioreactor was used. At these conditions, H. pluvialis accumulated 130 mg/L of Astaxanthin in 76 days and this result shows us that 25L polymer film type photobioreactor is better than small scale indoor condition. |
