The selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) using immobilized galactose oxidase in biphasic media presents a promising approach for biomass valorization. This study demonstrated that immobilization of galactose oxidase on suitable carriers allows for efficient conversion in systems containing up to 50% water, overcoming solubility issues of DFF and potential catalyst poisoning common in aqueous or purely organic systems. However, limitations such as enzyme deactivation and product adsorption to the support necessitate further research into more stable enzyme variants and optimized reaction conditions for industrial application.
