Unicellular green microalgae, haematococcus pluvialis, has been focused as a microbial source of astaxanthin production and astaxanthin has been suggested as a food supplement for humans. Haematococcus pluvialis accumulates the highest level of astaxanthin under severe condition. In this study, we developed new typed photobioreactor and improved reactor design&parts. Also, we studied correlation among light, astaxanthin, biomass using controlled indoor photobioreactor system. For efficient cultivation, we reformed v-neck degree and sparger size so we gained progressed mixing effect data. Indoor photobioreactor system composed of fluorescent lamp, carbon dioxide suppliment, reactor and temperature control system. Carbon dioxide supplied 2% concentration with normal air. Temperature is maintained 20~25℃. Controlled light intensity illuminated according to cell density. We draw mathematical relation for light intensity, astaxanthin, biomass based on this data.
