Figuring out the effect of Grifola frondosa Polysaccharide (GFP) on gut microbiota is increasingly recognized because of its widespread use in medicine area. In the present study, we investigated the potential influences of GFP with five molecular weight ranges on the gut microbiota, lipid content in serum and livers, and metabolic pathways in mice. GFP with each molecular weight range significantly changed the composition of the gut microbiota. Compared with the control (CK) group, GFP with five molecular weight ranges significantly changed Beta-diversity of the gut microbiota, especially EG3 (30-50k Dalton) group and the EG5 (⩾100k Dalton) group. GFP with five molecular weight ranges had no significant effect on the lipid profiles of the content of triglycerides (TG), total cholesterol (T-CHO), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) in serum. The EG4 (50-100k Dalton) group obviously reduced the content of TG and T-CHO, slightly increased the content of HDL-C, and slightly changed the content of LDL-C in liver. The EG1 (⩽10k Dalton) group, the EG2 (10-30k Dalton) group, the EG3 group and the EG5 group made the KEGG pathways changed. These findings illustrated that GFP positively affected the microbial environment in the gut microbiota and offered the experimental evidence for preparation of multi-functional diet or medicine.

Hard carbon (HC) anodes for sodium-ion batteries (SIBs) face challenges such as sluggish Na⁺ diffusion kinetics and structural instability. Herein, we propose a synergistic nitrogen-doping and defect-engineering strategy to unlock ultrahigh-rate capability and long-term cyclability in biomass-derived hard carbon. A scalable synthesis route is developed via hydrothermal carbonization of corn stalk, followed by controlled pyrolysis with urea, achieving uniform nitrogen incorporation into the carbon matrix. Comprehensive characterization reveals that nitrogen doping introduces tailored defects, expands interlayer spacing, and optimizes surface pseudocapacitance. The resultant N-doped hard carbon (NC-2) delivers a remarkable reversible capacity of 259 mAh g at 0.1 A g with 91% retention after 100 cycles. And analysis demonstrates a dual Na⁺ storage mechanism combining surface-driven pseudocapacitive adsorption (89% contribution at 1.0 mV s) and diffusion-controlled intercalation facilitated by reduced charge transfer resistance (56.9 Ω) and enhanced ionic pathways. Notably, NC-2 exhibits exceptional rate performance (124.0 mAh g at 1.0 A g) and sustains 95% capacity retention over 500 cycles at 1.0 A g. This work establishes a universal defect-engineering paradigm for carbonaceous materials, offering fundamental insights into structure-property correlations and paving the way for sustainable, high-performance SIB anodes.

Lithium-sulfur (Li-S) batteries are hindered by the sluggish kinetics of polysulfide conversion and rapid capacity decay. Herein, we report a heterostructured electrocatalyst for addressing polysulfide shuttling and accelerating redox kinetics via self-assembly of cobalt-based metal-organic framework (Co-MOF, CM) nanoparticles onto MXene (MX) nanosheets. The 0D CM acts as catalytic nano-reactors for efficient polysulfide adsorption and bidirectional conversion, while the 2D MXene substrate ensures rapid electron/ion transport and structural stability. The hierarchical architecture, featuring abundant meso/macropores and strong interfacial Co-S/Ti-S interactions, synergistically suppresses polysulfide shuttling and lowers reaction barriers. The optimized CM@MX cathode delivers high-rate capability (1161.5 mAh g −1 at 0.1 C, 314.7 mAh g −1 at 5 C) and cycling stability (63% capacity retention after 250 cycles at 1 C). Mechanistic studies reveal accelerated sulfur redox kinetics enabled by dual-active sites and optimized Li 2 S nucleation/dissolution dynamics. This work provides a scalable heterostructure design paradigm for high-performance Li-S batteries.

In this study, a platform was constructed for the efficient biosynthesis of a lactate-based copolymer using a phosphite dehydrogenase (PtxD)-based NADH regeneration strategy. PtxD catalyzes the conversion of phosphite to phosphate while reducing NAD + to NADH. The latter is an essential cofactor for lactate synthesis in Escherichia coli . This strategy allows the decoupling of NADH regeneration from carbon metabolism flow, providing sufficient NADH for lactate synthesis. Different concentrations of isopropyl β-d-1-thiogalactopyranoside (IPTG) were used to control the intensity of PtxD expression, and the lactate fraction in the copolymer synthesized by the engineered strain ranged from 6.2–16.7 mol%. The ptxD gene was integrated into the genome of strain WJPCTP-01, which successfully synthesized 3.24 g/L P(3HB- co -23.0 mol% LA) and 2.23 g/L P(3HB- co -39.0 mol% LA) using glucose and xylose as substrates, respectively, in shake flask cultures. In 5 L bioreactor fermentations, the titer of P(3HB- co -41.3 mol% LA) reached 8.57 g/L, with a synthesis rate of 0.12 g/L/h when xylose was used as a substrate. These findings indicate that the PtxD-based NADH regeneration strategy enhances lactate synthesis without any significant negative impact on bacterial growth or the synthesis of P(3HB- co -LA).

Glycerol, a major byproduct of biodiesel production, serves as a promising and versatile feedstock for synthesizing high-value chemicals. In this study, the NZN111, a potential succinic acid (SA) producer, was subjected to adaptive laboratory evolution (ALE) under selective pressure imposed by sodium acetate (NaAC) pressure. By analyzing the differences in the transcript levels of genes related to substrate utilization and product generation in the evolved strains, it was found that NaAC metabolism in Escherichia coli involves a series of enzymatic reactions that are apparently benefit for glycerol metabolism and SA biosynthesis. To further enhance the strain’s performance, a metabolic engineering strategy was implemented, including introduction of exogenous carboxykinases and HCO 3 − transporter proteins. The engineered strain produced 84.27 g/L SA in an anaerobic fermentation medium containing 100 g/L glycerol with a yield of 1.25 g/g glycerol, which was 1.38 and 1.16 times higher than those of the original strain, respectively. These findings highlight the potential of combining ALE with targeted metabolic engineering to develop robust microbial platforms for the efficient conversion of glycerol into high-value chemicals, contributing to the sustainable utilization of biodiesel byproducts.

Charge separation plays a crucial role in semiconductor-based photocatalytic CO2 conversion. Herein, we report a unique induced electric field, which can actively manipulate carrier behavior at the minuscule, leading to significantly boosted photocatalytic CO2 reduction in H2O vapor. The success relies on the development a monolithic photocatalyst made of a copper foam substrate and nanosized ZnO/NiO/Au heterostructures that can effectively couple a special rotating magnetic field (RMF). Specifically, the copper foam cuts the magnetic induction line, leading to the periodic generation of induced electric field. This induced electric field could significantly increase the carriers' density by preventing their recombination. Moreover, NiO and Au as the active sites for oxidation and reduction, respective, synergistically magnify this effect. As a result, compared with the photocatalytic reaction without adding RMF, the utilization rate of photogenerated electrons increases by 5.24 times after coupling RMF, with the yield of CO and CH4 improved by 5.50 times and 5.18 times. This strategy by integrating unique RMF into the reaction system provides new insights for improving photocatalytic CO2 conversion. © 2023, The Authors. All rights reserved.

Defect engineering in the inherently inert basal planes of transition metal dichalcogenides (TMDs), involving the introduction of chalcogen vacancies, represents a pivotal approach to enhance catalytic activity by exposing high-density catalytic metal single-atom sites. However, achieving a single-atom limit spacing between chalcogen vacancies to form ordered superstructures remains challenging for creating uniformly distributed high-density metal single-atom sites on TMDs comparable to carbon-supported single-atom catalysts (SACs). Here we unveil an efficient TMD-based topological catalyst for hydrogen evolution reaction (HER), featuring high-density single-atom reactive centers on a few-layer (7×7)-PtTe2-x superstructure. Compared with pristine Pt(111), PtTe2, and (2×2)-PtTe2-x, (7×7)-PtTe2-x exhibits superior HER performance owing to its substantially increased density of undercoordinated Pt sites, alongside exceptional catalytic stability when operating at high current densities. First-principles calculations confirm that multiple types of undercoordinated Pt sites on (7×7)-PtTe2-x exhibit favorable hydrogen adsorption Gibbs free energies, and remain active upon increasing hydrogen coverage. Furthermore, (7×7)-PtTe2-x possesses nontrivial band topologies with robust edge states, suggesting potential enhancements for HER. Our findings open up a new avenue for the development of TMD-based catalysts and exciting prospects for the exploration of topological materials in catalysis and beyond. © 2023, CC BY.
