Impact of hazardous components on CO2 biofixation from synthetic flue gas using Chlorella sp. JPR-1 in a raceway pond photobioreactor
This work aimed to investigate the effects of hazardous compounds (NO and SO2) in flue gas on Chlorella JPR-1growth in a raceway pond photobioreactor at ambient temperature (30 °C) without pH control. Chlorella JPR-1 exhibited itstolerant to CO2 content in the flue gas as high as 50%. The maximum ca...

| Summary: | This work aimed to investigate the effects of hazardous compounds (NO and SO2) in flue gas on Chlorella JPR-1growth in a raceway pond photobioreactor at ambient temperature (30 °C) without pH control. Chlorella JPR-1 exhibited itstolerant to CO2 content in the flue gas as high as 50%. The maximum carbon fixation rate (1.84 g CO2/L.day) observed whenthe flue gas contained 10% CO2. Although the specific growth rate was 25.88% lower than the control culture when cultivatedwith 50 ppm SO2, Chlorella JPR-1 still could grow when cultured with 100 ppm SO2 with slightly longer lag phase period.A growth rate reduction of 3.53% of the control culture was observed when Chlorella JPR-1 was cultured with flue gascontaining 50 ppm NO. This study has shown that Chlorella JPR-1 has a high potential to be used for CO2 fixation from fluegas. |
