Growth and cellulose production phenotypes of the strain CECT 8546 of Komagataeibacter europaeus. a with three different concentrations (5, 10, and 20 μg/ml) of the GqqA protein and BSA as a control after 16, 24, 48 and 72 h. b BSA as control, GqqA protein (20 μg/ml), QsdR1 protein (20 μg/ml), and GqqA protein (20 μg/ml) supplemented with the AHL molecules N-oxo-C8-l-HSL, N-C10-l-HSL and N-C12-l-HSL (50 μM of each) after 24 h. c GqqA protein (20 μg/ml) supplemented with individual AHL molecules (N-oxo-C8-l-HSL, N-C10-l-HSL and N-C12-l-HSL) at a final concentration of either 5 or 10 μM. All of these experiments were performed in triplicate
