“…The thermochemical catalytic reaction strategy of HMF production has been explored. 8 Deep eutectic solvent (DES) is a new type of ionic liquid, which has the unique advantages of easy preparation, high adjustability, low toxicity, low cost, satisfactory stability, and biodegradability, and has been developed to catalyze biomass to prepare high-value chemicals. 9 Using DES to catalyze the production of HMF from biomass has become a feasible means and has attracted much attention.…”

5-Hydroxymethyl-2-furfurylamine (HMFA) is an important furan chemical, which plays an important role in diuretics, antihypertensive drugs, and preservatives and can be obtained by amination of 5hydroxymethylfurfural (HMF). In this study, bread waste (BW) was chemoenzymatically transformed into HMFA via a one-pot two-step method through the tandem catalysis of deep eutectic solvent betaine/ formic acid (chemical catalyst) and Escherichia coli HILF cells (biocatalyst). First, the catalyst betaine/formic acid (10.0 wt %) was applied to catalyze BW (20.0 g/L) at 180 °C for 80 min, and the HMF yield reached 0.269 g HMF/g BW. Furthermore, coexpression of ω-transaminase HNIL [His (H) at AT210 was mutated to Asn (N) and Ile (I) at AT77 was mutated to Leu (L) in Aspergillus terreus transaminase] and lactate dehydrogenase (LDH) coupled with formate dehydrogenase (FDH) was utilized for biological amination and coenzyme regeneration, and the recombinant E. coli HILF was constructed by constructing a three-enzyme cascade catalytic reaction system. Using whole cells of HILF as a biocatalyst, the additional amount of D-alanine supplemented into the biological amination reaction was apparently reduced compared with that of the original transaminase. HILF cells could convert BW-derived HMF into HMFA (90.0% yield), and the yield was 0.243 g HMFA/g BW within 6 h. This hybrid strategy apparently reduced the dosage and cost of amine donors in biological amination and also laid the foundation for large-scale production of HMFA from BW.

“…Cellulose, the natural polymer of glucose units linked by β-1,4-glycosidic bonds, is one of the main components in lignocellulosic biomass. , Valorization of cellulose, typically by depolymerizing cellulose into poly-/oligo-/monosaccharides (oligosaccharides: 2–20 monosaccharide units; polysaccharides: 21–100 monosaccharide units) via hydrolysis and further converting into secondary platform chemicals (e.g., 5-hydroxylmethylfurfural (HMF), levulinic acid (LA), ethanol, lactic acid, etc. ), − represents a promising route in future lignocellulosic biorefineries. As such, the controllable depolymerization of cellulose to poly-, oligo-, and monosaccharides with a desired rate and polymerization degree (DP) is crucial to the tandem chemical conversions of cellulose to valuable chemicals.…”

Valorization of cellulose through tandem chemical conversions depends significantly on the controllable depolymerization of cellulose to poly-/oligo-/monosaccharides with the desired rate and degree. Herein, we report the controlled depolymerization of high-loading cellulose (15.0 wt %) into polysaccharides with a uniform polymerization degree of 38−48 by cetyltrimethylammonium bromide (CTAB) in water and its underlying mechanisms. We found that CTAB was adsorbed on the cellulosic surface via hydrophobic interaction, thereby acting as an "adhesive" for reducing the interfacial tension between H 2 O/ H 3 O + and the cellulosic surface, helping in swelling of the crystalline region, promoting depolymerization of the amorphous region, and inhibiting repolymerization of polysaccharides. Further kinetic study demonstrated an increment of ∼400 times in the preexponential factor (10 19.3 vs 10 16.7 min −1 ), 19.6 kJ•mol −1 in activation energy (181.5 vs 161.9 kJ•mol −1 ), and 3.5 times in rate constant for the CTAB-promoted depolymerization, which highlighted the offsetting of the elevated reaction energy barrier by boosting the collision frequency between H 2 O/H 3 O + and cellulose. Furthermore, we illustrated the synergistic role of 1,4-dioxane on this controllable depolymerization by lowering the activation energy to 143.7 kJ•mol −1 for reducing polysaccharide accumulation at the cellulosic interface. This in-depth understanding is of great significance for the sustainable transformation and utilization of cellulose in future biorefineries.
