Effects of dissolved inorganic carbon and mixing on autotrophic growth of Chlorella vulgaris

- NaHCO3 can be used for fast microalgal growth and effective CO2(g) supply to medium.
- High DIC concentration with mixing greatly enhances autotrophic growth.
- Use of NaHCO3 under mixing helps overcome DIC limitation for photosynthesis.
- Photosynthesis is limited by DIC supply followed by light during autotrophic growth.
- Use of NaHCO3 is limited by salinity generated by Na+ for freshwater algae.
