  1. Average ± standard deviation from 3 independent culture experiments is shown. Specific growth and glucose consumption rates were calculated using OD660 values (shown in Figure 2) and glucose concentrations in culture supernatant (data not shown) at the last three time points in each culture shown in Figure 2.
