Fig. 8From: Complete oxidation of hydroxymethylfurfural to furandicarboxylic acid by aryl-alcohol oxidase1H-NMR spectra along the reaction between HMF and AAO in the absence (a) and presence (b) of catalase. Spectra 1 and 1′ were obtained before enzyme addition. Spectra 2 and 2′ were recorded immediately after enzyme addition. The rest of spectra (3/3′ to 8/8′) show the evolution of the reaction products during long-term incubation at 25 °CBack to article page
