TABLE 2.
Physiological parameters for TMB3001, TMB3001C5 (class I), and TMB3001C1 (class II) in aerobic batch cultures with 5 g of xylose per liter
| Strain | Maximum growth rate (h−1) | Specific xylose uptake rate (g g−1 h−1) | YX/S (g g−1) | Maximum biomass concn (g liter−1) |
|---|---|---|---|---|
| TMB3001 | 0.016a | NDb | ND | 2.1c |
| TMB3001C5 | 0.064 | 0.13 ± 0.00 | 0.50 ± 0.02 | 1.9 |
| TMB3001C1 | 0.119 | 0.27 ± 0.02 | 0.45 ± 0.04 | 2.0 |
a
Aerobic growth on xylose as the sole carbon source was observed only after serial growth in YPX medium and YNB medium with 20 g of xylose per liter. The standard deviation for duplicate experiments was ±0.001.
b
ND, not determined.
c
The standard deviation was ±0.02.
