Vitamin D deficiency is a serious global health problem. Edible mushrooms are a good source of vitamin D for human health. The objective of this experiment was to investigate the efficiency of converting its precursor ergosterol to vitamin D2 in shiitake mushroom (Lentinus edodes) and oyster mushroom (Pleurotus ostreatus) powder in ethanol suspension under ultraviolet (UV) irradiation. UV irradiation conditions were optimized for several parameters, such as material form, wavelength, wavelength combination, and exposure time. Under the optimal conditions, UV irradiation increased the concentrations of vitamin D2 from undetectable to 40.59 ± 1.16 μg/g (dw) in dry shiitake mushroom powder and to 677.28 ± 40.42 μg/g (dw) (an approximately 16.69-fold increase) in ethanol suspension. The concentration of vitamin D2 increased from undetectable to 23.71 ± 5.72 μg/g (dw) in the dry oyster mushroom powder upon UV irradiation, whereas UV irradiation increased the concentration to 275.32 ± 48.45 μg/g (dw) (an approximately 11.61-fold increase) in the ethanol suspension. Comparing the effects of varying combinations of wavelengths showed that irradiation with UV-A, UV-C, or a combination of both is more effective than UV-B irradiation. In addition, the increase in vitamin D2 in shiitake mushrooms irradiated by UV-C was time-dependent, that is, dose-dependent. Nevertheless, the increase rates decreased with time. The concentration of ergosterol decreased with the increase in vitamin D2, but ergosterol was only partially converted to vitamin D2, whereas most of the ergosterol was probably UV-degraded. Exposure to ultraviolet light in ethanol suspension offers an effective way to increase the concentration of vitamin D2 and thus improve the nutritional value of edible mushrooms, as well as make them more functional as a source of vitamin D to improve the consumer health.

With the depletion of fossil fuels and rising environmental issues, there’s a pressing need for solar energy storage materials that boost solar utilization and decrease dependence on nonrenewables. Traditional organic phase change materials face limitations in solar energy storage applications due to their proneness to leakage and low light absorption coefficients. Herein, a novel strategy that involves the in situ polymerization of pyrrole on Pleurotus eryngii (Pe) biomass, addressing these challenges by improving light absorption while preserving the high porosity of Pe. The resulting phase change composites (PCCs) achieved an encapsulation rate of 89.7%, a light absorption rate of 96.1% within the wavelength range of 300–2500 nm, and an impressive photothermal conversion efficiency of 91.2% under simulated solar irradiation at an intensity of 5 suns. In summary, our innovative strategy effectively boosts the light absorption coefficient of Pe biomass while preserving its high porosity, providing a feasible solution for the large-scale and expedited manufacturing of solar photothermal energy materials. This work highlights the promise of biomass in driving renewable energy technology forward and supports the pursuit of sustainable energy solutions.

N and B co-doped carbon materials were prepared using urea and H 3 BO 3 as activators and Pleurotus eryngii as the carbon source. Structural characterization shows that the heteroatom content of PENB (co-modified by urea and H 3 BO 3 ) is as high as 62 %, which is much higher than that of carbon materials modified by a single activator. The specific surface area of PENB is 2.2 times that of PEB (modified only by H 3 BO 3 ) and 127.4 times that of PEN (modified only by urea). The high specific surface area of PENB can provide more active sites. The excellent structure of PENB can be attributed to the fact that urea and H 3 BO 3 retain heteroatoms in the reaction system through neutralization reaction, which promotes the contact between heteroatoms and biomass, thereby enhancing the etching effect of heteroatoms on carbon materials. In addition, N and B atoms can induce amorphous carbon materials to produce graphene microcrystals, which can enhance the electronic conductivity of PENB. Interestingly, this method of increasing the content of heteroatoms and generating graphene is also applicable to other biomass. Electrochemical tests show that PENB exhibits the highest electrochemical performance. The symmetrical supercapacitor (SSC) assembled with PENB has an energy density of 8.8 Wh kg −1 at a power density of 400 W kg −1 . After 10,000 cycles, the capacitance retention rate is 100 %. This work provides a new universal strategy to improve the heteroatom content of carbon materials and the preparation of graphene, which can well cope with the energy crisis.

The potential effects of probiotics on lowering lipid accumulation and alleviating gut microbiota perturbation have been extensively substantiated, but whether Lactobacillus rhamnoses-fermented oyster mushroom (FOM) could more pronouncedly attenuate obesity remains unclear. In this study, the anti-obesity effect of FOM was estimated based on the gut microbiota profile and analysis of hepatic lipid metabolic characteristics. The results revealed that FOM intervention dramatically improved hepatic lipid accumulation, characterized by reduction in fat-related factor metabolism levels and liver lesion enzymatic activities and down-regulation of the expression of genes associated with glycolipid metabolism (Foxo1, Gck, G6pd, Il6r and IL-β). Metabolomics analysis indicated HFD-induced dysglycaemia and disturbed amino acid metabolism, characterized by significant enrichment of pathways (butanoate metabolism, arginine biosynthesis, etc.) and elevated levels of D-mannose, succinate and β-D-fructose, followed by a decreased galactitol content. Furthermore, FOM intervention showed significant enrichment of specific pathways, particularly transcriptional misregulation in cancer and FoxO signaling pathways, while the MAPK signaling pathway demonstrated consistent enrichment across all experimental groups. FOM intervention reshaped the gut microbiota structure by facilitating the proliferation of SCFA producers (Romboutsia, Ruminococcaceae and Allobaculum), together with the depletion of Lachnospiraceae population. The current study strengthened our understanding of FOM prebiotic activities and obesity alleviation mechanisms.
