Residual enzymatic activity was measured in 30 mM Na₂CO₃/NaHCO₃ buffer (pH 10.5) containing various metal ions at 45 °C for 6 h. Values were expressed as mean ± SD (n = 3). Values were not sharing a similar superscript within the same column were significantly different (P < 0.05) as determined by ANOVA
