Chlorella Species | C. protothecoides | C. vulgaris | C. sorokiniana |
Strain | UTEX 411 | UTEX 265 | UTEX 1230 |
Specific Growth Rate, μ (d−1) | 0.48±0.01 | 0.84±0.09 | 1.77±0.04 |
0.32±0.05 | 0.23±0.01 | 0.36±0.05 | |

The major heterotrophic and photoautotrophic growth parameters for each Chlorella strain were calculated using data points from the exponential phase of batch culture. Bold values correspond to heterotrophic populations; regular typeface represents autotrophic rates. All kinetic quantities are reported as the average of biological replicates ± standard deviations.
