An Effective Hybrid Strategy for Conversion of Biomass into Furfurylamine by Tandem Pretreatment and Biotransamination
In this work, an effective hybrid strategy was developed for tandem conversion of biomass to furfurylamine with tin-based solid acid Sn-Maifanitum stone and recombinantEscherichia coliwhole cells harboring omega-transaminase. 90.3 mM furfural was obtained from corncob (75 g/L) at 170 degrees C for 0.5 h over Sn-Maifanitum stone catalyst (3.5 wt%) in the aqueous media (pH 1.0), which could be further bioconverted into furfurylamine at 74.0% yield (based on biomass-derived furfural) within 20.5 h. Finally, an efficient recycling and reuse of Sn-Maifanitum stone catalyst and immobilizedEscherichia coliAT2018 whole-cell biocatalyst was developed for the synthesis of furfurylamine from biomass in the one-pot reaction system.
