Growth, carbohydrate consumption, and metabolite production of Bacteroides thetaiotaomicron LMG 11262a
| Carbohydrate | Mean consumption ± SD (mM FE) of substrate (after 48 h) | Mean production ± SD (mM) of metabolites (after 48 h) |
CRb (%) | Substrate depletion time (h) | Maximal cell population (CFU ml−1)c | |
|---|---|---|---|---|---|---|
| Succinate | Acetate | |||||
| Fructose | 49.9 ± 0.4 | 54.3 ± 0.3 | 36.5 ± 0.3 | 92.5 | 6-9 | 8.5 × 109 |
| Oligofructose | 56.3 ± 0.1 | 65.1 ± 1.2 | 34.1 ± 1.5 | 90.6 | 6-9 | 1.1 × 1010 |
| Inulin | 47.4 ± 0.2 | 61.7 ± 1.5 | 23.4 ± 1.5 | 91.6 | 18-24 | 1.6 × 1010 |
a
Bacteria were grown in a medium for colon bacteria supplemented with 50 mM FE of fructose, oligofructose (OraftiP95), or inulin (OraftiHP).
b
Including theoretical carbon metabolism (37).
c
Assessed at 9 h for fructose or oligofructose supplementation or at 24 h for inulin.
