Fig. 6From: Exploring the contributions of two glutamate decarboxylase isozymes in Lactobacillus brevis to acid resistance and γ-aminobutyric acid productionEffects of temperature (a) and pH (b) on the effective maximum specific growth rate of Lb. brevis. L. brevis CK and L. brevis 9530: pNZ8148-gadBC cells were cultured in GYP medium at different temperatures and pH values. Influence of temperature (c) and pH (d) on the cell-bound GAD activity of L. brevis. L. brevis CK and L. brevis 9530: pNZ8148-gadBC cells were grown to the late exponential growth phase (24 h) under acidic conditions (pH 5.2). GAD activities were measured in 0.2 mol/L sodium acetate buffer containing 60 mmol/L of MSGBack to article page
