DS production in L. mesenteroides NRRL B-512F grown with different carbon sourcesa
| Carbon source (117 mM) | DS activity (U · mg of protein−1) | Production (fold) |
|---|---|---|
| d-Xylose | 0.005 | 1 |
| d-Glucose | 0.039 | 8 |
| d-Fructose | 0.050 | 10 |
| d-Glucose + d-fructose | 0.104 | 21 |
| Sucrose | 2.390 | 478 |
Cells were cultured at 25°C. Activity was measured after the late exponential growth phase. Supernatants were concentrated 40-fold.
