CO2 fixation by Chlorella sp. HA-1 and its utilization

Abstract Growth response of Chlorella sp. HA-1 against NOx and SOx were investigated. Chlorella sp. HA-1 was tolerant to an air containing 10% CO2 and NOx which corresponded to the stack gas from LNG thermal power plant. Chlorella sp. HA-1 cells contained 0.57g protein and 0.18g lipids per g dry cells. Its artificial digestibility was 85.9%, so high value as Chlorella cells. These results indicate that the HA-1 cells are valuable as a fodder for the livestock.
