Figure 3. Glucose uptake by M. chelonae ATCC 35752 and its isogenic porin knock-out mutants.

The accumulation of [U-¹⁴C]glucose by the strains over time was measured as described under Materials and Methods. Glucose uptake rates were calculated on the first 10 min of the reactions. Uptake experiments were performed in triplicates and are shown with their standard deviations.
