Thesystem operated for 15 weeks under controlled conditions, achievinga maximum removal efficiency of 80% and an overall average efficiencyof 60.98%. In silico studies indicated viable microbial metabolicpathways for acetone, and the low binding energy of the fungus Penicillium chrysogenum suggests a complementaryrole in the degradation of byproducts generated in the photocatalyticstage. The synergistic combination of advanced oxidation and microbialbiodegradation enabled an effective pollutant removal. Microbial successionwas observed during operation with an increase in fungus toleranceto adverse conditions.

In this study, ultrasound-assistedextraction (UAE) and high-shear mechanical extraction (HSME) weresystematically compared for the aqueous recovery of phenolic compoundsfrom mangosteen peel byproduct. Both processes were evaluated in termsof extraction performance, phenolic selectivity, energy demand, temperaturerise, and process scalability. While HSME promoted a broader and lessselective release of phenolic compounds, reaching total phenolic concentrationsof up to 1161 ± 8 μg GAE/mL, UAE favored the enrichmentof specific phenolic subclasses, particularly anthocyanin-rich fractions,achieving 97 ± 3 μg C3OG/mL of total anthocyanins and ahigher proportion of red pigments (44 ± 1% vs. 38 ± 1% forHSME), and resulting in higher antioxidant capacity despite comparabletotal phenolic contents. Energy demand was assessed by distinguishingbetween energy effectively transferred to the medium, determined througha calorimetric approach, and electrical energy required at the systemlevel, revealing contrasting energy delivery modes between shear-and cavitation-driven processes. Although UAE delivered higher specificenergy to the extraction medium (up to 130.4 kJ/kg vs. 56.2 kJ/kgfor HSME), its batch operation and process complexity impose scalabilityconstraints, whereas HSME exhibited lower energy demand per unit massand greater operational robustness. A process-level sustainabilityassessment highlighted clear trade-offs between selectivity, energydemand, and scalability. Overall, the results demonstrate that energydelivery mode is a key design variable in aqueous phenolic extraction,providing a rational basis for selecting extraction strategies accordingto targeted phenolic profiles and process constraints.","PeriodicalId":29804,"journal":{"name":"ACS Engineering Au","volume":"6 3","pages":"463–476"},"PeriodicalIF":9.0,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148624831","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}

We evaluate many of the efficient viewpointsand advantages itaconic acid offers for the currently engineered systemsthat use fossil-based compounds and precursors. Unlike similar functionalmolecules and species, such as acrylates, methacrylates, or vinylesters, itaconic acid’s liquid derivatives exhibit negligiblevolatility, thereby reducing potential health hazards and VOC emissions.Moreover, countless derivatives can be proposed and synthesized whenappropriate nucleophiles are selected (e.g., alcohols, amines, andothers). Due to the two vacant carboxyl acid groups (−COOH),itaconic acid can be incorporated into multicomponent polyesters,polyethers, polyamides, or other functional systems to enhance theirperformance, improve processability, or ensure degradability.
