a Schematic diagram of NhaA activity assay. b Bars display the ratio of fluorescence dequenching upon NaCl addition and fluorescence quenching upon lactic acid addition. Data represent mean ± SD (n = 3). Statistical analysis was conducted using a two-sample t-test (*: P < 0.05). c Correlation between Na⁺/H⁺ antiporter activity and the CFA/SFA ratio, with the R² value of a linear trendline shown.
