GO-containing hydrogels had a significant effect on methylene blue adsorption and this effect increased with an increase in the amount of GO. PAA/XG/GO hydrogels can be introduced as an eco-friendly adsorbent with high efficiency for the removal of cationic dye pollutions. Infectious diseases such as Listeria monocytogenes infection pose a great threat to the health of human beings and the development of livestock and poultry farming. Currently the treatment of Listeria infection mainly relies on antibiotics, which may result in excessive antibiotic residues in livestock and poultry products, as well as causing an increase in the occurrence of zoonotic diseases. Here, we demonstrate that Succinoglycan Riclin promoted the clearance of Listeria in the in vitro and in vivo infection model. The expression and secretion of inflammatory cytokines including IL-6 and IL-1β were significantly increased after Riclin treatment upon infection. The protective effect of Riclin was mainly through activating MAPK/IL-6 axis. HO-1/IL-1β signaling pathway was less important in this process. Moreover, Riclin caused significant metabolic changes including pathways involved in glycolysis, protein synthesis and oxidative stress during Listeria infection. These results suggest a potential use of Succinoglycan Riclin as non-antibiotic preventive and therapeutic anti-microbial agent in livestock and poultry farming and human diseases. The chitin deacetylase CDA3 from C. cinerea deacetylated chitin-oligosaccharides with dp ≥ 2. Since CDA3 firstly removed the intermediate acetyl group of (GlcNAc)4, it was an endo-acting deacetylase. Different from previously reported deacetylation modes, CDA3 deacetylated chitinbiose at either the reducing end or the nonreducing end; CDA3 deacetylated chitintriose at any subsite including the end and the intermediate; CDA3 further removed acetyl groups at any subsite, the intermediate, nonreducing and reducing end of chitintetraose after removal of the first intermediate acetyl group. 3D structural analysis showed that CDA3 has aromatic amino acids distributing at both the +1 and -1 subsites of the catalytic site, which may be responsible for its distinctive deacetylation mode. Furthermore, CDA3 was active on crystalline chitin, its deacetylation activity increased with the DA decreases of chitinous substrates and showed a higher activity towards the cell wall of the basal stipe with the higher molar ratio of GlcN/GlcNAc than that of the apical stipe with the lower molar ratio of GlcN/GlcNAc. CDA3 with distinctive deacetylation mode and activity indicates its function during the maturation of the fruiting bodies of C. cinerea and a potential for preparation of mushroom chitosan for application in the food, cosmetics, and pharmaceutical industries. Food-grade Pickering emulsions have attracted lots of researchers' attention. As one type of food-grade particles, tea water-insoluble protein nanoparticles (TWIPN) from tea residues were utilized to prepare Pickering emulsions at an oil-water ratio of 6 4 (v/v) via high-pressure homogenization (HPH). Characteristics and rheological behavior of TWIPN-stabilized Pickering emulsions (TWIPNPE) were analyzed. The size of TWIPNPE significantly decreased with the increase of homogenization pressure (0-80 MPa) and homogenization times. However, the droplet size of TWIPNPE at 120 MPa significantly increased compared to that at 80 MPa. Furthermore, the droplet size and zeta potential of TWIPNPE prepared at a fixed homogenization pressure of 40 MPa reduced in comparison with those prepared via high-speed homogenization at the same TWIPN concentration (0.5-4.0%). Besides, the emulsions prepared at the TWIPN concentration of 3.0% and 4.0% had no creaming within 50 days. Additionally, HPH improved the gel-like behavior of TWIPNPE. These results suggest that the TWIPNPE have the potential for preparing the high viscoelastic system for the food industry to expand the utility of tea leave byproducts. This study was targeted to investigate the effect of chitosan-loaded nanoemulsion enriched with two types of essential oils on the microbial quality of turkey meat. To this end, the effects of essential oils of Zataria Multiflora Boiss (ZEO) and Bunium persicum Boiss (BEO) were evaluated at two concentrations (0.5% and 1% (w/v)) during 18 days of storage at 4 °C. Initially, in vitro evaluations were performed on the prepared nanoemulsions, namely essential oil nanoemulsions and chitosan-loaded nanoemulsions containing essential oils, using micro-dilution method and agar diffusion methods, respectively. Meat samples were analyzed for microbial indicators and inoculated salmonella Enteritidis, and Listeria monocytogenes during 3-day intervals. The highest reduction rate of total viable bacteria (2.06 log CFU/g), total psychrophilic (2.59 log CFU/g), Pseudomonas spp. (2.07 log CFU/g), Enterobacteriaceae (2.51 log CFU/g), lactic acid bacteria (2.51 log CFU/g), and yeast and mold count (2.10 log CFU/g) were observed in chitosan-loaded nanoemulsion containing ZEO 1%, in comparison with control samples. Semaglutide agonist Moreover, the shelf life significantly increased due to the application of chitosan-loaded nanoemulsions (15-18 days), compared to that of the control group (6 days). Therefore, the edible chitosan-based nanoemulsion could play an effective role in the preservation of the microbial qualities of turkey meat. Rapid industrialization is polluting the water resources and is becoming a serious environmental issue. In present study, the adsorption-desorption behavior of Direct Orange-26 (DO-26), Direct Red-31 (DR-31), Direct Blue-67 (DB-67) and Ever direct Orange-3GL (EDO-3) dyes on to native, modified rice husk (MRH), polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC) and alginate (ALG) immobilized biomasses were investigated under different experimental conditions. For adsorbent modification, physical and chemical treatments were performed. The results showed that HCl pre-treatment considerably increased the sorption capacity of dyes versus native biomass. The sorption data were optimized using pseudo 1st order, intra-particle diffusion, pseudo 2nd order and Elovich models. The results revealed that the two-step rate equation was followed for the desorption kinetics of dyes. The involvement of -OH (hydroxyl), -COOH (carboxylic) and -NH2 (amino) groups in the adsorption of dyes onto biomasses was shown by FTIR analysis.
