The synthesized composites were utilized in batch experiments to assess their efficacy in removing eosin yellow (EY) dye from aqueous solutions. The influence of critical parameters such as initial solution pH, adsorbent dosage, and contact time on the adsorption capacity was rigorously examined. The adsorption results demonstrated that the newly developed composites are highly effective adsorbents for EY dye. The adsorption process was accurately modeled using the pseudo-second-order (PSO) kinetic and Langmuir isotherm models. Experimental data revealed that the maximum adsorption capacity of KR-3 for EY, measured at pH 4.0 and a temperature of 325 K, reached 151.5 mg g^− 1. The maximum adsorption capacity was also 136.99 mg g^− 1 for KR-1 and 130.07 mg g^− 1 for KR-2. Thermodynamic analyses determined that the adsorption mechanism is predominantly physisorption, characterized by a spontaneous and endothermic nature. Additionally, regeneration studies underscored the favorable recyclability of the adsorbent materials.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 7","pages":"3158 - 3173"},"PeriodicalIF":5.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, zinc oxide shows antimicrobial and UV-blocking properties, and when incorporated into aerogels, it could enhance the shelf life of packaged food by preventing the growth of bacteria and the degradation related to sensible light compounds. The present work is focused on fabricating a novel composite ZnO-Agarose aerogel produced by supercritical drying using biogenic zinc oxide nanoparticles produced by using a wine processing waste extract as reducing agent. Such particles showed a mean size of 92 nm and an energy band gap of 2.98 eV, similar to that of commercial ZnO (3.22 eV). The effect of ZnO loading into agarose (AG) aerogels was investigated and compared to commercial ZnO. The presence of ZnO gets better the mechanical stability and the porosity by reducing the pores’ mean size from 0.068 μm for pristine agarose aerogel to 0.036 μm for 1% wt ZnO loaded one. Moreover, a higher hydrophobicity (CA = 75°) and lower swelling degree (153%) were observed for ZnO loading agarose aerogel. The composite agarose aerogel exhibited a generally higher reflectance from 41% (pristine AG) to 80% (AG + 1% ZnO) over the considered solar wavelength range. This effect is associated with the presence of ZnO, which determines a light scattering effect promoting the increase in UV Protection Factor (UPF) up to 15. The produced systems can be potentially employed in the secondary food packaging area.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 7","pages":"3174 - 3189"},"PeriodicalIF":5.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10924-025-03583-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many microorganisms have been reported as PHA producers, but only a few can utilise xylose as a carbon source for their production. In this study, five xylose-utilising PHA producing bacteria (two mesophilic and three thermophilic) were isolated from decomposing SCB and assessed. Among the five isolates, <i>Mycolicibacterium smegmatis</i>, reported for the first time as a PHA producer, accumulated the highest amount of PHA using xylose (22% cell dry weight). <i>M. smegmatis</i> was then tested for its ability to utilise a mixture of simple sugars (2 glucose: 1 xylose) and alkaline pretreated SCB hydrolysate without any detoxification step. The results showed bacterial growth in both media; however, growth was lower in the media supplied with the hydrolysate (0.63 g L⁻¹) compared with a mixture of glucose and xylose (1.11 g L⁻¹), presumably due to the presence of inhibitors in the hydrolysate. PHA accumulation was similar in media supplied with hydrolysate or mixture, with 27% and 28% cell dry weight, respectively. The extracted biopolymer was studied by Fourier Transform Infrared (FTIR) spectroscopy, Gas Chromatography Mass Spectrometry (GC-MS) and Scanning Electron Microscopy (SEM) and identified as polyhydroxybutyrate (PHB).

In both cases, the PDX mat degraded far faster (almost complete degradation in vivo on day 30) than the PLA mat (~ 30% thickness reduction on day 60).
