Quantification of GlcNAc in culture supernatant by DNS colorimetric assay in WT, WT (pEKEx3) and ∆nanR (pEKEx3-SP0955-chiB-SP0955-nagA2). Values and error bars represent the mean and the standard errors of triplicate cultures. All results were tested for significance using the paired heteroscedastic Student’s t-test. The level of significance of the differences observed between the control and test samples was expressed as one, two or three stars, for * p ≤ 0.05, ** p ≤ 0.01 and *** p ≤ 0.001, respectively. “NS” stands for nonsignificant
