From: The mechanisms of condensed tannins inhibit Pediococcus pentosaceus
Effect of condensed tannins (CTs) on the cell membrane of Pediococcus pentosaceus SF11. Minimum inhibitory concentration (MIC): addition of CTs at the MIC concentration of 1500 mg/L. a Potassium ion efflux in cells. b Molecular absorbance at 260 nm in cells. c Changes in the intracellular fluorescence intensity of 2-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino)-2-deoxyglucose (2-NBDG) in cells. d Changes in the fluorescence intensity of 2-NBDG after incubation for 4 h. Different uppercase letters on the columns represent significant differences between the treatments (P < 0.05), and different lowercase letters on the columns represent significant differences over time (P < 0.05)
