 The study found that adding xylenase enzymes to cellulase enzymes improved the hydrolysis of cellulose in pre-treated lignocellulosic substrates. This synergy between the two enzymes led to greater accessibility of the cellulose, which in turn increased the rate of hydrolysis and decreased the amount of enzyme needed for optimal results.
