Doubling times of wild-type and mutant strains in TY medium with proline and glycinea
| Strain | Genotype | Doubling time (min) in: |
||
|---|---|---|---|---|
| TY medium alone | TY medium + proline | TY medium + glycine | ||
| JIR8094 | Wild type | 55.41 ± 2.00 | 41.51 ± 0.18 | 56.51 ± 2.72 |
| LB-CD4 | prdB::erm | 57.43 ± 2.43 | 55.81 ± 0.68 | 54.43 ± 2.57 |
| LB-CD12 | grdA::erm | 57.44 ± 3.00 | 39.11 ± 0.57 | 58.67 ± 1.57 |
| LB-CD8 | prdR::erm | 63.83 ± 6.99 | 70.41 ± 4.13 | 64.15 ± 4.63 |

Strains were grown in TY medium alone or supplemented with 30 mM l-proline or 30 mM glycine. Doubling time was calculated during a 60-min period starting at 120 min of growth; values are means ± standard deviations.
