Particle sizes and zeta potentials in L. mesenteroides-fermented bovine milk. (A) Bacterial electricity measured by voltage changes (mV) was recorded for 60 min in the presence (+ G) or absence (-G) of glucose. (B) The formation of dense solid (arrow) and pH values were observed in fermented milk (FM), not non-fermented milk (M). Bar = 0.5 cm. (C) Particle sizes (d.nm; diameter in nanometers) and zeta potentials (mV) (D) of non-fermented milk (M) and fermented milk (FM) were compared. The p-values of < 0.001 (***) with mean ± SD from experiments in triplicate were displayed
