The present study tests different cellulose particles extracted from plants to produce hydrogels and identify if these particles and hydrogels have antimicrobial properties. Nine cellulose particles from Ecuadoran biodiversity were obtained using an established chemical extraction protocol, characterized using known techniques, and evaluated for bacterial growth in-vitro. In addition, two particles of nine were selected to perform bacterial growth rates and bacterial adhesion assays. The bacterial growth rates with cellulose F1 and F53 were similar to the positive control (with antibiotic) with both Escherichia coli ATCC 25922 and TG1 strains. However, the results showed that the bacterial growth rate with seven of the nine cellulose particles was lower than the negative control (without antibiotics) suggesting antifouling properties. Based on the results using cellulose particles and hydrogels with antifouling properties, we prepared a plant extract to test the bactericide properties against Gram-positive (Staphylococcus aureus ATCC 25923) and Gram-negative (E. coli ATCC 25922) bacteria, evidencing the highest inhibitory effect at 40 and 60 mg/mL against S. aureus and E. coli, respectively. Lastly, we encapsulated the bactericide plant extract into the anti-fouling hydrogel. The results demonstrated that the combination of antifouling and bactericide properties could be an alternative approach for surface-modified cellulosic materials applications in the future.","PeriodicalId":409762,"journal":{"name":"Frontiers in Soft Matter","volume":"26 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139957332","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}

Alkyl polyglucosides are known to stabilize oil-in-water emulsions and here, we report their use in combination with fatty alcohol for the stabilization of all-aqueous water-in-water (W/W) emulsions based on dextran-in-poly(ethylene glycol). Two different APGs were used: decyl glucoside and lauryl glucoside. We systematically studied the influence of the concentrations of APGs, and the molar ratio between the APGs and decanol as model fatty alcohol on the size and stability of the aqueous emulsion droplets with time. The self-assembled structure formed by decanol/APGs was characterized by using Small Angle X-ray Scattering and confocal microscopy, and shown to be lamellar in the bulk phase and probably also at the surface of dextran-rich droplets. We also demonstrated that the stabilization of W/W emulsions can be extended to other alkyl polyglucoside and to other fatty alcohols. In addition, we reported the production of a foam using such W/W emulsions as the continuous phase. Our results show that it is possible to stabilized W/W emulsions using LGNs based on different APGs and fatty alcohols, which will undoubtedly expand the use of W/W emulsions for various fields.","PeriodicalId":409762,"journal":{"name":"Frontiers in Soft Matter","volume":"34 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139206051","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}
