Cloning, Expression, and Characterization of a Novel Thermophilic Monofunctional Catalase from Geobacillus sp. CHB1

Figure 8

Optimal pH of the recombinant catalase. The buffers used for each pH region were 50 mM sodium citrate (pH 4–6), 50 mM sodium phosphate (pH 6–8), and 50 mM glycine-NaOH (pH 9–11). Each pH was assayed at least three times.
