  abstract = {{P}retreatment of sugar-cane bagasse ({SCB}) by laccases from {P}ycnoporus sanguineus under solid-state fermentation ({SSF}) can favour dephenolisation of the substrate prior to ethanol production. {T}o define adequate conditions for this biological pretreatment, an experimental design and surface plot analysis were performed using as independent variables: yeast extract, fungal inoculum and substrate amounts after different incubation times. {L}accase and cellulase activities and chemical characterisation of the substrate by {C}-13 {CP}/{MAS} (cross-polarization at magic angle spinning) {NMR} (nuclear magnetic resonance) were used as responses. {A}fter 60 days of {SSF}, yeast extract enrichment and low amounts of inoculum enhanced dephenolisation of {SCB}. {M}oreover, yeast extract reduced the quantity of crystalline cellulose without strongly promoting cellulases and polysaccharide degradation. {H}igh amounts of inoculum decreased laccase activities and substrate dephenolisation.},
