Lignocellulosic residues have huge potential as alternative renewable energy sources. However, lignin surrounds cellulose and hemicellulose in a complex structure that makes plant biomass highly recalcitrant to the microorganisms and enzymes that are needed for the conversion of sugars into ethanol. To extract cellulose, a diversity of pretreatments is needed. In order to evaluate the ability of the white rot fungus Trametes versicolor, a diversity of pre-treatments were analysed and the composition of the sugars released was determined. The ethanol production was measured in each case. Interestingly, pre-treatment T. versicolor resulted in a greater mono-sugar content and ethanol production in Populus spp. samples. Finally, T. versicolor was clustered with four different microorganisms in terms of genes that encode plant cell wall degrading enzymes and found to belong to the same cluster as Coprinopsis cinerea in terms of beta-xylosidase protein.
