Data were obtained from two independent fermentation processes, and each sample was analyzed in triplicate. a–dValues (mean of the triplicate) followed by different letters within the same column are significantly different (Tukey’s honestly significant difference, p < 0.05). PDM, polymer dry mass; n (-), flow behavior index; K (Pa⋅sn), consistency index; η3.96 (Pa⋅s), apparent viscosity; WHC, water holding capacity.
