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 recombinant Escherichia coli whole cells harboring ω-transaminase. 90.3 mM furfural was obtained from corncob (75 g/L) at 170 °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 immobilized Escherichia coli AT2018 whole-cell biocatalyst was developed for the synthesis of furfurylamine from biomass in the one-pot reaction system.

在这项工作中，开发了一种有效的杂交策略，用于将生物质与锡基固体酸Sn-Maifanitum石和带有ω-转氨酶的重组大肠杆菌全细胞串联转化为糠胺。在水介质（pH 1.0）中，在170℃下，通过Sn-Maifanitum石催化剂（3.5 wt％），从玉米芯（75 g / L）中提取90.3 mM糠醛，可以将其进一步生物转化为74.0％的糠胺20.5小时内产量（基于生物质衍生的糠醛）。最后，开发了一种高效回收利用Sn-Maifanitum石催化剂和固定化大肠杆菌AT2018全细胞生物催化剂，用于在一锅法反应系统中从生物质合成糠胺的方法。
