Fig. 4: Rheology of EpsA-O.

a The flow curves of EpsA-O dissolved in MSgg. The data points are color-coded and shaped according to the concentration of dissolved EpsA-O as follows: blue squares: 1 g/dL; blue circles: 0.5 g/dL; blue triangles: 0.2 g/dL; green squares: 0.1 g/dL; green circles: 0.05 g/dL; orange squares: 0.01 g/dL; orange circles: 0.005 g/dL; red stars: 0.001 g/dL; purple squares: 0.0005 g/dL. b Zero-shear viscosity of EpsA-O dissolved in MSgg at different concentrations indicating two critical concentrations, c* and c**. c Reduced viscosity (ηsp/c) as a function of EpsA-O dissolved in dH2O or MSgg at different concentrations. Blue squares and trendline represent EpsA-O dissolved in dH2O, while red circles and trendline represent EpsA-O dissolved in MSgg. d Flow curves of EpsA-O aqueous solutions in the presence of increasing NaCl concentrations. Black squares: dH2O; blue circles: EpsA-O in dH2O (0.5 g/dL); red triangles: EpsA-O in 0.05 M NaCl (0.5 g/dL); green diamonds: EpsA-O in 0.1 M NaCl (0.5 g/dL); blue pentagons: EpsA-O in 0.5 M NaCl (0.5 g/dL); orange hexagons: EpsA-O in 1 M NaCl (0.5 g/dL). e Amplitude sweep test of EpsA-O dissolved in MSgg at different concentrations. The squares represent the storage modulus (Gʹ), and the circles represent the loss modulus (Gʺ). The color coding for the symbols and lines indicates different concentrations: green for 1 g/dL, orange for 0.5 g/dL, and blue for 0.15 g/dL. f Loss factor as a function of EpsA-O concentration in MSgg.
