We explored the isolation, purification, preliminary structure characterization, and potential applications of an exopolysaccharide (HS, 6.68 g/L) produced by <em>Herbaspirillum</em> sp. S-1. Through DEAE Sepharose fast flow column chromatography and Sephacryl S-200, we obtained a single fraction of the exopolysaccharide (S-1). Monosaccharide composition analysis revealed that S-1 mainly consisted of D-mannose, D-glucose, and D-galactose, with an average molecular weight of 4.995 × 10³ g/mol, respectively. Further analyzes indicated that the main chain repeating unit of S-1 was →4)-α-D- Manp-(1→6)-β-D-Galp-(1→3)-α-D-Glcp-(1→6)-β-D-Galp-(1→3)-α-D-Glcp-(1→6)-β-D-Galp-(1→. Moreover, the <em>in vitro</em> determination of antioxidant activities demonstrated that S-1 exhibited notable antioxidant properties, with ∼85.6 %. S-1 has high activity in inhibiting α-glucosidase (∼52.79 %) and α-amylase (∼46.26 %). HS and S-1 exhibited anti-proliferative effects on HT-29 and BEL-7402 cells, whereas S-1 had higher anti-proliferative activity than HS. Furthermore, it exhibited good synergistic thickening performance with sclerotium gum. Consequently, the S-1 exopolysaccharide has potential for application as a natural antioxidant and additive in functional food and related industries.</div></div>","PeriodicalId":100213,"journal":{"name":"Carbohydrate Polymer Technologies and Applications","volume":"10 ","pages":"Article 100842"},"PeriodicalIF":6.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanical properties, water barrier, surface hydrophobicity, optical and UV–visible barrier properties were determined. The films produced were transparent with excellent optical appearance and good preventive ability against UV radiation. HPMC based films with glycerol as plasticizer were more compact and had lower thickness (45.43±3.33 μm) and higher young’s modulus, indicating stiffer, less flexible films (1613.22±492.88 MPa). In contrast, films plasticized with oleic acid had the highest elongation at break (30.35±4.21 %), indicating greater flexibility. The films with glycerol were hydrophilic (contact angle equal to 81.47±6.65°) while the films with fatty acids (oleic and linoleic acid) were hydrophobic (contact angle &gt; 90°). The hydrophobic films had also better water barriers compared to films with glycerol. All tested packaging materials resulted in similar preservative effect on packed gilthead seabream fillets, leading in shelf life 7–8 days at 2 °C.

Congo red (CR), an anionic azo dye, poses significant environmental hazards to aquatic and terrestrial ecosystems. This study explores the use of a positively charged adsorbent composite for the effective removal of CR via adsorption. Chitosan (CS) based composite, CS-GA-<em>β</em>-CD/ZnO, was synthesized by grafting <em>β</em>-cyclodextrin (<em>β</em>-CD) onto cationic CS using glutaraldehyde (GA) in the presence of ZnO nanoparticles. The composite’s physicochemical characteristics were evaluated using various analytical techniques. The effects of pH, contact time, temperature, initial CR concentration, and adsorbent dosage on CR removal were systematically investigated through isotherm, kinetic, and thermodynamic analyses. The composite demonstrated high adsorption efficiency, particularly at adsorbent dosages ≥30 mg, with optimal performance under acidic conditions due to its enhanced surface positivity. The presence of salts had minimal impact on adsorption efficiency, confirming the robustness of the material. Thermodynamic studies indicated spontaneous adsorption within 300 minutes. The adsorption behavior was best described by Liu, Dubinin-Radushkevich (D-R), and Langmuir isotherm models, with a maximum capacity (i.e., Langmuir qₘ) of 337 ± 13 mg g⁻¹ at <em>T</em> = 30 °C. The composite retained over 93% of its adsorption efficiency after five regeneration cycles, highlighting its reusability. Moreover, an artificial neural network (ANN) model provided accurate predictive capability with an R² &gt; 0.995. These findings underscore the potential of CS-GA-<em>β</em>-CD/ZnO as a cost-effective, environmentally friendly, and scalable adsorbent for CR removal from wastewater. CS-GA-<em>β</em>-CD/ZnO is not explored for its adsorption potential and therefore, the outcome of the present work can advance the knowledge in the field of achieving good dye removal from the aqueous solution using composite materials.
