B. longum NCC 2705 promoter activities measured using different reporter systems in mid-exponentially grown cells. Background activity/fluorescence of the wildtype and recombinant strains harboring reporter genes under the control of Pgap (grown on glucose) or PBL1518 (grown on glucose or raffinose) was measured through β-glucoronidase (A), fluorescence emitted by mCherry (B) and fluorescence emitted by the anaerobic cyan-blue Pp1 (C). Values represent average of biological triplicates. Significant differences were calculated using one-way ANOVA, followed by a Sidak’s multiple comparison test (**P-value < 0.01; ****P-value < 0.0001).
