Pleurotus ostreatus (P. ostreatus) is one of the most popular edible mushrooms worldwide and has been proposed as a candidate for human selenium (Se) supplementation. This study developed a Se-biofortification method, and evaluated the effect of 2,4-Dichlorophenoxyacetic acid (2,4-D), Na2SeO3 addition amounts and initial pH on P. ostreatus mycelium growth, nutritional value, and mineral accumulation. The optimal growth conditions were identified as 2,4-D 2.00 mg L-1, Na2SeO3 30.65 mg L-1, and initial pH 5.97 by Box-Behnken design. The optimization resulted in the biomass of 15.75 g L-1 and the organic Se content of 594.85 mg Kg-1, which was 2.50 and 8.03 times higher than the control group, respectively. In parallel, the contents of polysaccharides, proteins, essential amino acids, major functional components, and several minerals in mycelium were increased to varying degrees. Above results indicated that 2,4-D could be an effective stimulant for Se biofortification. © 2024, The Authors. All rights reserved.

Phosphorus-Modulated Surface Active Center Reconstruction in Cerium Oxide for Polyols Conversion into Carbonates

SSRN

SSRN 2024年

作者： Wang, Jie Huang, Jielin Dong, Li Chen, Songsong Zhang, Junping Zhang, Suojiang School of Chemical Engineering University of Chinese Academy of Sciences Beijing100049 China Beijing Key Laboratory of Ionic Liquids Clean Process CAS Key Laboratory of Green Process and Engineering State Key Laboratory of Mesoscience and Engineering Institute of Process Engineering Chinese Academy of Sciences Beijing100190 China Longzihu New Energy Laboratory Zhengzhou Institute of Emerging Industrial Technology Henan University Zhengzhou450000 China

Cerium oxide (CeO2) was prepared in phosphonium-based ionic liquids and P-CeO2 materials were obtained by doping phosphorous (P) on the surface of CeO2. Meanwhile, the surface physicochemical properties of materials and the catalytic reaction process for polyols conversion into carbonates were analyzed by XRD, FT-IR, TGA, TEM, BET, Raman, XPS, CO2-TPD, NH3-TPD, and in situ FT-IR tests. The results indicated that the P doping induced the surface reconstruction of CeO2, and an appropriate content of P could generate both Lewis acidic and basic sites related to P on the catalyst surface. Moreover, the P-mediated frustrated Lewis acid-base pairs (FLPs) could effectively promote the dissociation of substrates and the formation of critical intermediates, leading to the excellent catalytic performance of the prepared materials for synthesising carbonates from polyols. Under mild experimental conditions, the yield and selectivity of ethylene carbonate (EC) were 77.26% and 95.99%, much higher than other reported CeO2 catalysts. © 2024, The Authors.
