<P><B>Abstract</B></P> <P>In this study, chemo-enzymatic synthesis of furfuralcohol from biomass-derived xylose was successfully demonstrated by a sequential acid-catalyzed dehydration under microwave and whole-cells reduction. After dry dewaxed chestnut shells (CNS, 75 g/L) was acid-hydrolyzed with dilute oxalic acid (0.5 wt%) at 140 °C for 40 min, the obtained CNS-derived xylose (17.9 g/L xylose) could be converted to furfural at 78.8% yield with solid acid SO<SUB>4</SUB> <SUP>2−</SUP>/SnO<SUB>2</SUB>-Attapulgite (2.0 wt% catalyst loading) in the dibutyl phthalate-water (1:1, v:v) under microwave (600 W) at 180 °C for 10 min. In the dibutyl phthalate-water (1:1, v/v) media at 30 °C and pH 6.5, the furfural liquor (47.0 mM furfural) was biologically converted to furfuralcohol by recombinant <I>Escherichia coli</I> CCZU-Y10 whole-cells harboring an NADH-dependent reductase (PgCR) without extra addition of NAD<SUP>+</SUP> and glucose, and furfural was completely converted to furfuralcohol after 2.5 h. Clearly, this one-pot synthesis strategy can be effectively used for furfuralcohol production.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Chestnut shells (CNSs) were used to produce furfural and furfuralcohol. </LI> <LI> One-pot chemo-enzymatic catalysis was demonstrated in dibutyl phthalate-water media. </LI> <LI> Furfural was produced by SO<SUB>4</SUB> <SUP>2−</SUP>/SnO<SUB>2</SUB>-Attapulgite under microwave at 180 °C for 10 min. </LI> <LI> Bioreduction of furfural was conducted without extra addition of NAD<SUP>+</SUP> and glucose. </LI> <LI> Biosynthesis of furfuralcohol from furfural was performed by a fed-batch strategy. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
