Robust production of pigment-free pullulan from lignocellulosic hydrolysate by a new fungus co-utilizing glucose and xylose

Cost-efficient production of pullulan is of great importance but remains challenging due largely to the high-cost carbon sources. Lignocellulosic biomass is considered an alternative carbon source for industrial pullulan production, while new fungus producers that co-utilizing lignocellulose-derived glucose and xylose are required.
