The biological fixation using microalgae has been known as an effective and economical carbon dioxide reduction technology. Carbon dioxide (CO2) fixation by microalgae has been shown to be effective and economical. Among various algae, a species Euglena gracilis was selected as it has advantages such as high protein content and high digestibility for animal feed. A kinetic model was studied in order to determine the relationship between specific growth rate and light intensity. The half-saturation constant for light intensity in the Monod model was 178.7 mu mol photons/m(2)/s. The most favorable initial pH, temperature, and CO2 concentration were found to be 3.5, 27 degrees C, and 5-10% (vol/vol), respectively. Light intensity and hydraulic retention time were tested for effects on cell yield in a laboratory-scale photo-bioreactor of 100 1 working volume followed by semi-continuous and continuous culture. Subsequently, an innovative pilot-scale photo-bioreactor that used sunlight and flue gas was developed to increase production of this bioresource. The proposed pilot-scale reactor showed improved cell yield compared with the laboratory-scale reactor. (c) 2005 Elsevier Ltd. All rights reserved.
