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. © 2021 IEEE.

biomass resources are natural polymeric materials that are abundant, affordable, non-toxic and renewable. Although they find diverse applications in both everyday life and high-tech materials, their use is often constrained by the associated fire hazards. To address this issue, there is a growing interest in the development of flame-retardant biomass polymeric materials. Metal-organic frameworks (MOFs) consist of transition metal species, flame-retardant elements and potential carbon sources, allowing for easy adjustment of their structure and properties. This versatility makes MOFs and their derivatives and hybrids highly attractive for flame retardancy studies. Despite their distinctive properties, MOFs alone may not fully satisfy the demands of commercial flame-retardant applications. The combination of MOFs with biomass materials has been identified as a promising strategy for developing efficient flame-retardant biomass nanocomposites. This innovative approach aims to address the limitations of MOFs by capitalizing on synergistic effects. This review highlights recent advancements and strategies in MOF-based flame retardants incorporating biomass materials, and it elucidates the flame-retardant mechanisms of MOF/biomass nanocomposites to inform future design efforts in the field. Furthermore, the review discusses the current challenges and prospects in this field, aiming to provide a succinct yet comprehensive overview for researchers to quickly grasp the latest developments.

materials with red room-temperature phosphorescence (RTP) derived from sustainable resources are crucial but rarely reported. Here, we produced red RTP materials from lignin. Lignin was covalently modified with Upy (1-(6-isocyanatohexyl)-3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl) urea) to obtain Lig-Upy. The Upy in the Lig-Upy promoted the interaction between the aromatic units of lignin and reduced energy gaps of these molecules. As a result, Lig-Upy exhibited red RTP centered at 625 nm with a lifetime of 24.2 ms. Moreover, the hydrogen bonding interactions in Lig-Upy varied when embedded into different matrices, such as polyvinyl alcohol (PVA) or sodium montmorillonite (MTM), inducing a change in RTP wavelength and lifetime. Utilizing these properties, Lig-Upy was used as building blocks for producing materials exhibiting time-dependent phosphorescent colors (TDPCs). Such TDPCs materials have exhibited great potential for visual decorations, information encryption and anti-counterfeiting logos for medicine bottles.
