Enhancing the enzymatic digestibility of oil palm biomass using supercritical carbon dioxide-based pretreatment towards biorefinery application

In realizing the vast potential of lignocellulosic biomass residues generated by oil palm industry under the regime of ‘one-size-fits-all’ biorefinery concept, supercritical carbon dioxide (SC-CO2) technology offers great promise. Herein, we demonstrated a new eco-friendly pretreatment of oil palm...
