Effect of CO2 on lipid accumulation in microalgae
| Microalgae | CO2 concentration | Lipid accumulation | References |
|---|---|---|---|
| Chlorella sp. BTA 9031 | 3% (v/v) | Accumulated 25% of lipid as a percentage of dry cell weight | Aratboni et al. (2019) |
| Chlamydomonas sp. JSC4 | 4% (v/v) | Generated maximum lipid content (65.3%) and productivity (169.1 mg/L/day) | Aratboni et al. (2019) |
| Chlorococcum littorale | 5% (v/v) | Lipid content increased up to 34% wt | Mondal et al. (2016) |
| Scenedesmus obliquus CNW-N | The optimal CO2 consumption rate was 1420.6 mg/L/day | The highest productivity of lipid (140.35 mg/L/day) is achieved | Ho et al. (2017) |
| Synechocystis sp. PCC6803 | 3% (v/v) | The total lipid content increased up to 14% of dry weight | Cuellar-Bermudez et al. (2015) |
| Porosira glacialis | 20–25% levels of CO2 | The total lipid content increased from 8.91 to 10.57% in cell dry mass | Artamonova et al. (2017) |
| Attheyolongicornis | 20–25% levels of CO2 | Did not show any significant increase in total lipid content | Artamonova et al. (2017) |
| Nannochloropsis oculata | 3% (v/v) | Demonstrated high lipid content (53.2 wt.%) | Udayan et al. (2017) |
| Scenedesmus sp. | 10% CO2 | Lipid productivity reached up to 20.65 mg/L/day | Yoo et al. 92010) |
| Chlorella vulgaris | 30% CO2 | The highest lipid content 45.68% is obtained | Aratboni et al. (2019) |
