Recently, the cost-effective production of high value-added furan chemicals from inexpensive, abundant, and renewable bioresources has gained much attention via a chemoenzymatic approach in an environmentally friendly reaction system. Furfurylamine is an important furan-based chemical for the production of additives, fibers, perfumes, agrochemicals, and pharmaceuticals. This study attempted to develop one sustainable approach for the production of furfurylamine via chemoenzymatic cascade catalysis of biomass into furfurylamine using a chemocatalyst and a biocatalyst. Using alkali-treated shrimp shells as the biobased support, a tin-based heterogeneous chemocatalyst (Sn-DAT-SS) was first prepared to transform corncob into furfural in 52.4% yield in deep eutectic solvent choline chloride:ethylene glycol (ChCl:EG)–water (10:90, v/v) at 170 °C within 0.5 h. Sn-DAT-SS was easy to recover and has good reusability. Detailed investigation using Fourier transform infrared (FT-IR) spectroscopy, Brunauer–Emmett–Teller (BET) analysis, temperature-programmed desorption of NH3 (NH3-TPD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) indicated that the Lewis and Brönsted acid sites existed on the surface of Sn-DAT-SS. The possible catalytic mechanism of the Sn-DAT-SS-catalyzed transformation of corncob into furfural in ChCl:EG–water was presented. To biologically synthesize furfurylamine, newly constructed recombinant Escherichia coli CCZU-XLS160 whole-cells harboring ω-transaminase and l-alanine dehydrogenase were used to catalyze biomass-derived furfural using available inexpensive NH4Cl (2.0 mol NH4Cl/mol furfural) as the amine donor in ChCl:EG–water (10:90, v/v) at 35 °C and pH 7.5. Within 71.5 h, 92.3 mM furfural derived from corncob was wholly transformed into furfurylamine with a productivity of 0.39 g furfurylamine/g xylan in corncob in ChCl:EG–water (10:90, v/v). This work demonstrated an environmentally friendly chemoenzymatic strategy for utilizing lignocellulosic biomass into furfurylamine via tandem chemocatalysis and biocatalysis in green reaction media. It was feasible to obtain furfurylamine from a renewable source consisting of corncob and shrimp shells.

“…The content of M5HF2C of each mutant in the Fries 3 medium was consistent with the expression of Clpks18 gene. In the Fries 3 medium, the Clpks18 deleted mutants’ acetaldehyde dehydrogenase low expression (unpublished data), which maybe related to the M5HF2C biosynthesis ( Peng et al, 2019 ). However, the difference between the content of M5HF2C toxin in maize leaves infected by WT and other mutants was not significant ( Figure 6A ).…”

Plant pathogenic fungus Curvularia lunata (Wakker) Boedijn causes leaf spot diseases in several plants such as Oryza sativa, Sorghum bicolor (L.) Moench, and Capsicum frutescens. It has been spread worldwide, specifically in maize-growing regions. The polyketide synthase (PKS) plays a significant role in secondary metabolite production and its effect on virulence. The Clpks18 of C. lunata strongly correlated with its pathogenicity. The role of Clpks18 gene on the pathogenic activity of C. lunata remains unclear. Hence, in this study, we analyzed the importance of Clpks18 gene on the hyphae and conidial melanization and on the sporulation and hyphal growth. The deletion of Clpks18 gene reduced the production of methyl 5-(hydroxymethyl)furan-2-carboxylate toxin. The virulence of ΔClpks18 mutant was significantly reduced compared with the wild type. The metabolomics data revealed that (R)-(-)-mellein was a vital factor in the virulence of C. lunata. The (R)-(-)-mellein and the toxin produced by C. lunata were detected in the maize leaves during its infestation. In addition, the metabolomic analysis showed that the Clpks18 gene influences glycerolipid, non-ribosomal peptide biosynthesis, and its metabolism. This study demonstrates that the Clpks18 gene is important for the pathogenicity of C. lunata by influencing the complex metabolic network.

“…Besides the chemical synthesis of FCA, Peng et al reported an efficient one-pot chemo-enzymatic approach for the conversion of rice straw to form FCA through a tandem catalyst with Sn-sepiolite and whole-cell harboring horse liver alcohol dehydrogenase (HLADH) under mild reaction conditions. 60 The Sn-sepiolite could effectively convert rice straw to furfural in 42.2% yield at 170 °C for 20 min. Subsequently, the resulting furfural could be completely oxidized to FCA with E. coli TS whole-cells within 96 h at room temperature.…”
