Relative enzymatic activity of the extracellular fraction of C. bescii strains on oat spelts and birchwood xylans. Activity of extracellular protein (25 µg/mL concentrated protein) on oat spelts and birchwood xylans was measured after 12 h incubation at 75 °C in triplicate. JWCB21, the parent strain used in these experiments (see Table 2 for genotype details); JWCB73, the E1 expression strain; JWCB74, the E1 expression strain containing Acel_0180; JWCB75, the E1 expression strain containing Acel_0372
