TABLE 2.
Generation times
| Sugar (0.2%) | Mean generation timea (min) ± SE

|---|---|---|---|
| SMQ-301 | SMQ-301K01 | S. salivarius | |
| Lactose | 25 ± 0 | 26.5 ± 2.8 | 27.3 ± 0.8 |
| Galactose | No growth | 54.4 ± 4.9 | 29.8 ± 1.3 |
Growth was monitored by following the OD660. Generation times were calculated for cultures in the exponential growth phase by plotting the logarithm of the OD660 as a function of time. Values represent the means of three separate experiments.
