Combined effects of light intensity and carbon dioxide concentration on photoautotrophic growth of Haematococcus pluvialis |
| 초록 |
Increased concentration of carbon dioxide in the atomosphere is considered to be one of main causes of global warming probelm. Therefore, various attempts have been conducted for reducing and storing carbon dioxide. In this study, we used a microalga Haematococcus pluvialis to reuse carbon dioxide. This strain have been taken a great attention due to hyper-accumulation of high level of astaxanthin (up to 4%) which is a high-value carotenoid (US$ 2500 kg-1). A potent producer of astaxanthin, H. pluvialis has distinictive life cycle, which is associated with a morphological transformation from green vegetative cells stage to thick walled red cells stage. To use this alga for reuse carbon dioxide some important factors (e.g., CO2 concentration, light intensity) affecting algal growth should be investigated. In this work the combined effects of CO2 concentration and light intensity were studied. At 5%(v/v) of CO2 concentration, the maximum specific growth rate was obtained without inhibition by high light intensity up to 180 μE m-2 s-1. However, when the light intensity was lower than 50 μE m-2 s-1, the growth rate at 0.035%(v/v) was higher than that at 5%(v/v). |
