Characterization of cellulolytic enzymes produced in transplastomic plants. Specific activity of endo-β-1,4-xylanase (xyn) vs temperature (a) and pH (c). Thermostability of xyn at 50, 65, 75 and 85 °C (e, rhombus, squares, triangles and circles, respectively). Specific activity of β-glucosidase (celB) vs temperature (b) and pH (d). Thermostability of celB at 90 and 100 °C (f, rhombus and squares, respectively). The assays related to the evaluation of specific activity vs pH were performed in citrate/phosphate and sodium phosphate buffers in the ranges 3.0–6.0 and 6.0–8.0, respectively
