ESTIMATION OF OPERATING FACTORS FOR THE CONTINUOUS CARBON DIOXIDE FIXATION BY EUGLENA GRACILIS Z
As carbon dioxide (CO2) is believed to be the primary contributor to the greenhouse effect, a lot of effort has been made to decrease it. Among many technologies, the biological carbon dioxide fixation using microalgae has been known as an effective CO2 reduction technology. With many environmental factors influencing microalgal productivity, the desirable operating factors were investigated using a green alga, EUGLENA GRACILIS that has the high protein and vitamin E enough to be used as fodder. In batch culture, the optimum initial pH, temperature, CO2 and light intensity were found 3.5, 27°C, 5–10% and 520μmol/m2/s, respectively. As a medium to cultivate Euglena, tap water without sterilization was effective while freshwater needed pH control. Half-velocity coefficient (KI) in Monod model under photoautotrophic condition was 86.68 μmol/m2/s. In this study, the optimum hydraulic retention time (HRT) for the continuous CO2 fixation was 3 days at the optimum cultivation conditions obtained at batch experiment.
