Xiujuan Wang,Yue Chen,Yuhua Wang,Weichang Dai,Chun Hong Piao,Hansong Yu 한국식품과학회 2021 Food Science and Biotechnology Vol.30 No.13
Lipoxygenase-based and lipoxygenase-deficientokara were modified by Kluyveromyces marxianus fermentation,then adding modified okara back to the correspondingsoymilk to prepare soy yogurt. Thephysicochemical properties, texture, and volatile componentsof soy yogurt were characterized. The results showedthat okara modified by Kluyveromyces marxianus fermentationwas rich in soluable dietary fiber and was impartedbetter water-holding capacity, swelling capacity, and oilholdingcapacity. The soy yogurt with the modified okarawas greatly enhanced in its appearance, texture and wasrelatively stable during storage. Moreover, lipoxygenasebasedsoy yogurt had a unique soybean flavor whilelipoxygenase-deficient soy yogurt had a slight beany flavorand soybean flavor. This article guides a bio-modifiedmethod for okara and provides a theoretical basis for thefurther development and application of soy yogurt withhigh dietary fiber as well as lipoxygenase-deficient soyyogurt.
RPK118, a PX Domain-containing Protein, Interacts with Peroxiredoxin-3 through Pseudo-Kinase Domains

RPK118 is a sphingosine kinase-1-binding protein that has been implicated in sphingosine 1 phosphate-mediated signaling. It contains a PX (phox homology) domain and two pseudo-kinase domains, and co-localizes with sphingosine kinase-1 on early endosomes. In this study we identified a novel RPK118-binding protein, PRDX3 (peroxiredoxin-3), by yeast two-hybrid screening. The interaction between these proteins was confirmed by pull-down assays and co-immunoprecipitation experi-ments. Deletion studies showed that RPK118 inter-acted with PRDX3 through its pseudokinase domains, and with early endosomes through its PX domain. Dou-ble immunofluorescence experiments demonstrated that PRDX3 co-localized with RPK118 on early endosomes in COS7 cells. PRDX3 is a member of the antioxidant family of proteins synthesized in the cytoplasm and functioning in mitochondria. Our findings indicate that RPK118 is a PRDX3-binding protein that may be involved in transporting PRDX3 from the cytoplasm to its mitochondrial site of function or to other mem-brane structures via endosome trafficking

Strains of the fungal genus Pestalotiopsis are reported as large promising sources of structurally varied biologically active metabolites. Many bioactive secondary metabolites with diverse structural features have been derived from Pestalotiopsis. Moreover, some of these compounds can potentially be developed into lead compounds. Herein, we have systematically reviewed the chemical constituents and bioactivities of the fungal genus Pestalotiopsis, covering a period ranging from January 2016 to December 2022. As many as 307 compounds, including terpenoids, coumarins, lactones, polyketides, and alkaloids, were isolated during this period. Furthermore, for the benefit of readers, the biosynthesis and potential medicinal value of these new compounds are also discussed in this review. Finally, the perspectives and directions for future research and the potential applications of the new compounds are summarized in various tables.

Sulfur-free exfoliated graphite (EG) with large exfoliated volume (760 mL g-1) was prepared throughchemical oxidation, followed by microwave exfoliation. SEM results indicated that well-developednetwork pores in the worm-like structure of EG could be clearly observed. XPS results displayed thatsome functional groups were yielded on the surface of the as-prepared EG. Moreover, the capacity of EGwas evaluated by the adsorption of rodamine B and 4-chlorophenol aqueous solution. Results showedthat EG exhibited high adsorption capacity for RhB and 4-CP, which could be attributed to the functionalgroups and well-developed network pores in the worm-like EG.

Graphite/C-doped TiO2 composite was synthesized through a modified sol–gel reaction. DRS resultsindicated that light absorbance edge of graphite/C-doped TiO2 was clearly red-shifted to visible lightregion by doping with C. SPS results displayed that separation efficiency of photoinduced charge carriersof graphite/C-doped TiO2 were greatly increased by coupling with graphite. Moreover, the photocatalyticperformance of composite was evaluated by the degradation of methyl orange (MO). Results showedthat graphite/C-doped TiO2 exhibited higher photocatalytic activity for MO than that of pristine TiO2 andP25, which was mainly attributed to the high crystallization, large surface hydroxyl groups, intensevisible light absorption and effective separation of photoinduced charge carriers.

Nitrogen-doped mesoporous carbon spheres (NMCSs) supporting anatase TiO2 (NMCSs – TiO2) were prepared by a simple two-step solvothermal approach. The characterizations for the physicochemical properties of prepared samples under different solvothermal temperatures were carried out by X-ray diffraction (XRD) analyses, scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption – desorption (Brunauer – Emmett – Teller (BET) measurements), Fourier transform infrared (FT-IR) spectroscopy, Raman scattering and UV-Vis diffuse reflectance spectra, were combined in order to determine the crystal phase and grain size, shape, degree of mesoporous carbon incorporation, and nature of the resultant oxy-carbide chemical bonding on the surface and in the bulk. The high relative photocatalytic activity of NMCSs – TiO2 nanoparticle was evaluated through a study of the decomposition of phenol under visible-light excitation.
