Lignocellulosic biomass is an abundant and renewable feedstock for biofuels, biochemicals and biomaterials. To make this recalcitrant biomass more susceptible to hydrolysis and microbial conversion a pretreatment is required. Many pretreatments have resulted in high sugar yields; however, they can generate microbial inhibi-tory compounds in the fermentation step. Therefore, the detoxification of hydrolysates is necessary. This study shows that reduced graphene oxide adorned with magnetite nanoparticles (rGO-MNPs) can adsorb inhibitory compounds such as furfural. Adsorption tests were performed in both aqueous solutions (furfural and furfuralglucose) and wood hydrolysate. rGO-MNPs (20 mg) removed 68% of furfural when it was alone, 49% of furfural when it was mixed with glucose and 20% of furfural in the wood hydrolysate. Among the adsorption of furfural in wood hydrolysate, rGO-MNPs adsorbed other lignin derivate compounds. Finally, no toxic effect of rGO-MNPs on R. toruloides-1588 was observed during the fermentation using detoxified wood hydrolysate.
