Efficient cellulose degradation by cellulase enzymes is crucial for using lignocellulosic biomass in bioenergy production. Single-molecule microscopy showed that xylan hinders the efficiency of cellulase by inhibiting its binding to cellulose and impeding the processivity of bound enzyme molecules.
