Abstract

One-pot multienzyme continuous cascade for the conversion of HMF to FDCA using HRP to activate GOaseM _3-5 in situ.

Abstract

By manipulating the reaction conditions, furandicarboxylic acid (FDCA) was prepared by the biooxidation of hydroxymethyl furfural (HMF) in a continuous one-pot reaction using galactose oxidase M _3–5, periplasmic aldehyde oxidase (PaoABC), catalase and horseradish peroxidase. In addition, PaoABC was successfully entrapped in a SiO ₂ hydrogel and recycled 14 times without loss of activity. The catalyst was able to tolerate up to 200 mM DFF concentration giving FDCA in full conversion with very promising TOF and TON values.
