FIGURE 3.
Conversion versus time profiles of the complete cellulase system and the single cellulases used in this study. The highest degree of conversion is achieved by the synergistic action of the complete cellulase system (3.6 mg/gsubstrate). When solely CBH I (36 mg/gsubstrate) is present, the hydrolysis rate declines at a pronouncedly lower degree of conversion. CBH II (1.3 g/gsubstrate) and EG (36 mg/gsubstrate) show a pronounced preference for the amorphous regions, which is reflected in a higher overall conversion of the primarily amorphous substrate as compared with CBH I.
