Abstract
|
|
|
|
Feasibility of large-scale photobioreactors for biological CO fixation was investigated using Chlorella sp. HA-1. Generally, as the volume of photobioreactor increased, the CO fixation rate decreased because of a lower illumination efficiency in large-scale than in small-scale photobioreactors. Though controlling the arrangement and the number of light source, the maximum CO fixation rates that could be achieved were 530 and 357 gCO/㎡day for 40 L and 188 L photobioreactor, respectively, which was higher than the CO fixation rate of lab-scale photobioreactor.
