Comparison of growth rates and increase in formate concentrations in mediuma
| Strain | Log-phase growth rate (h−1)b | Final cell density (OD600)b | Maximal formate concn (μM)b | Fold increase in formate vs parent |
|---|---|---|---|---|
| PSY580a | 0.15 ± 0.01 | 6.59 ± 0.26 | 0 ± 0 | |
| PSY3646 (parent) | 0.15 ± 0.00 | 6.15 ± 0.22 | 154 ± 3 | 1 |
| PSY3648 | 0.15 ± 0.01 | 7.60 ± 0.09 | 696 ± 21 | 4.5 |
| PSY3649 | 0.18 ± 0.01 | 8.25 ± 0.14 | 2820 ± 237 | 18 |
a
All strains were grown in SC medium with 2% galactose.
