Concentrations of 1,2-PD metabolites produced by L. innocua strains grown in l-rhamnose mediuma
| Carbon source | Avg concn (mM) ± SD of metabolite producedb
|
P valuec | ||
|---|---|---|---|---|
| Lin11 (significant difference value) | Lin11Δ1118 (significant difference value) | Lin11Δ1118/pJX1118 (significant difference value) | ||
| 1,2-PD | 0.04 ± 0.02 | 0.02 ± 0.01 | 0.04 ± 0.01 | 0.67 |
| n-Propanol | 0.06 ± 0.02 (2) | ND (3) | 0.28 ± 0.03 (1) | 0.001 |
| Propionate | 0.25 ± 0.07 (1) | ND (3) | 0.09 ± 0.02 (2) | <0.001 |
a
Values are expressed as average mM concentrations ± standard deviations (SD) (n = 6). ND, not detected, i.e., concentrations are at least 50-fold lower than that observed for the Lin11 strain.
b
Metabolite concentration values that are significantly different between strains are indicated by numbers in parentheses (1, 2, or 3), with 1 assigned to the highest concentration and 3 assigned to the lowest concentration.
c
P values were calculated to determine if the concentration of each metabolite differed for the three strains.
