Biological pretreatment of lignocellulosic biomass uses the ligninolytic potential of certain microorganisms (fungi and bacteria) to reduce the recalcitrance of the feedstock and enhance its digestibility by hydrolytic enzymes. Ligninolytic enzyme systems have been studied mostly in white rot fungi, a type of wood decay fungi that is able to degrade lignin effectively, using a set of high redox potential oxidoreductases. Biological pretreatment can be performed by growing the microorganism directly on the feedstock or using the enzyme extracts. Recent advances in molecular biology have expanded knowledge about existing ligninolytic systems, including the discovery of new enzymes and the development of engineered systems with potential for effective pretreatment and full utilization of lignocellulosic biomass in biorefineries.
