the ability of fungal aryl-alcohol oxidase (AAO) to oxidize 5-hydroxymethylfurfural (HMF) results in almost complete conversion into 2,5-formylfurancarboxylic acid (FFCA) in a few hours. The reaction starts with alcohol oxidation, yielding 2,5-diformylfuran (DFF), which is rapidly converted into FFCA by carbonyl oxidation, most probably without leaving the enzyme active site. AAO is combined with an unspecific peroxygenase, UPO, EC 1.11.2.1, from Agrocybe aegerita for full oxidative conversion of 5-hydroxymethylfurfural in an enzymatic cascade. This peroxygenase belongs to the recently described superfamily of hemethiolate peroxidases, and is capable of incorporating peroxide-borne oxygen into diverse substrate molecules. In contrast to AAO, the UPO reaction starts with oxidation of the HMF carbonyl group, yielding 2,5-hydroxymethylfurancarboxylic, which is converted into 2,5-formylfurancarboxylic acid and some 2,5-furandicarboxylic acid
