Description

CO2 fixation by a blue green algae, Spirulina platensis, was evaluated using volumetric mass transfer coefficient (KLa). The specific surface area of the cells was measured with an image analyzer, and the specific surface area of the cell was evaluated and statistical distribution of the cell length was analyzed. CO2 mass transfer coefficient kCO2L was evaluated with the specific surface area of the cell (a). The surface area of each cell (ad) was about 5.0 (m2/g-d.m.), and CO2 mass transfer coefficient kCO2L ranged between 0.8×10-4 and 1.0×10-4 (m/day). The value of kCO2L during the linear growth phase was found to decrease to one fifth of the maximum. The distribution of the cell's surface area in the late growth phase (14-th day) also correlated well with the Weibull distribution. It was found that the mixing caused cell destruction.
