a Cell disposition of cultures of the strain CECT 8546 of Komagataeibacter europaeus after 16 h with the GqqA protein or BSA visualized by epifluorescence microscopy with the Live/Dead BacLight Kit. b Turbidity measurements at 600 nm during the growth of the strain CECT 8546 of Komagataeibacter europaeus at different concentrations of the GqqA protein: 20 μg/ml (black solid line), 10 μg/ml (gray dotted line), 5 μg/ml (black dotted line), and 5 μg/ml of BSA as a control (gray solid line). c) Glucose decrease in the medium GY during the growth of the strain CECT 8546 of Komagataeibacter europaeus with either 20 μg/ml of GqqA protein (gray line) or BSA (black line). Error bars represent standard deviations. Values are the mean of three measurements
