Cellobiose growth characteristics for strains expressing CdtG and Ls120451.
| Strain | Maximum growth rate (h−1) | OD600a | Cellobiose consumption (g/L/h)b | Final ethanol concentration (g/L)a | Ethanol yield (g/g cellobiose)a | Productivity (g/L/h)a |
|---|---|---|---|---|---|---|
| CdtG | 0.194 ± 0.012 | 4.77 ± 0.05 | 0.19 ± 0.01 | 1.46 ± 0.45 | 0.14 ± 0.05 | 0.03 ± 0.01 |
| Ls120451 | 0.142 ± 0.006 | 4.72 ± 0.03 | 0.20 ± 0.01 | 2.20 ± 0.06 | 0.18 ± 0.01 | 0.05 ± 0.00 |
Each value is the average of two replicates with the range of measurements.
a
Values for OD600, final ethanol concentration, ethanol yield and productivity were calculated from 56 h time point.
b
Cellobiose consumption rates were calculated from 8 to 56 hours.
