Abstract |
Biological fixation was studied to reduce the CO₂ emitted from thermal power plant. Euglena glacilis was used as a photosynthetic microorganism. In culture experiments, we investigated characteristics of Euglena growth and CO₂ fixation for the various conditions : influent CO₂ concentration, light intensity, pH, temperature, nitrogen and phosphorous concentration. Immobilized Euglena was also used to fix CO₂. The maximum growth of Euglena was obtained from the influent CO₂ concentration 5∼10%. But the growth of Euglena was partly inhibited above 10% CO₂. Therefore, it was suggested that Euglena glacilis was one of the suitable strain to fix CO₂ emitted from a LNG thermal power plant. Optimal light intensity for the growth of Euglena was considered between 4 and 7 klux. It required 19.28㎎ - N and 8.69㎎ - P to get lg of Euglena biomass. The maximum biological CO₂ fixation was obtained at pH 6 and 27℃. Immobilized Euglena had not the capability of fixing CO₂. |
