Sustainable Chemoenzymatic Cascade Transformation of Corncob to Furfuryl Alcohol with Rice Husk-Based Heterogeneous Catalyst UST-Sn-RH

Valorization of the abundant renewable lignocellulose through an efficient chemoenzymatic strategy to produce furan-based platform compounds has raised great interest in recent years. In this work, a newly prepared sulfonated tin-loaded rice husk-based heterogeneous chemocatalyst UST-Sn-RH was utilized transform corncob (75.0 g/L) into furfural (72.1 mM) at 170 °C for 30 min aqueous system. To upgrade furfuryl alcohol, whole cells recombinant E. coli KPADH harboring alcohol dehydrogenase were employed corncob-derived and pH 7.5. established cascade process, efficiently transformed with productivity 0.304 g alcohol/(g xylan corncob). general, biomass could be valorized valuable chemicals tandem reaction (bio-based UST-Sn-RH) biocatalyst (KPADH cell) system, which potential application.
