From: Effect of polyols on thermostability of xylanase from a tropical isolate of Aureobasidium pullulans and its application in prebleaching of rice straw pulp

Figure 4

Thermostability profile of the purified xylanase from A. pullulans CBS 135684 cultivated in basal medium containing 1% corncob. The purified enzyme solubilized in 50 mM of sodium acetate buffers (pH 6.0) and separately incubated at 40°C (▲), 45°C (Δ), 50°C (♦), 55°C (⋄), 60°C (■), 65°C (□) and 70°C (•) prior to enzyme assay at standard pH and optimal temperature. The residual xylanase activity was calculated as the percentage of initial enzyme activity (before incubation). Experiments were performed in triplicate (N = 3) and error bars indicated standard deviations.
