Although traditional biological treatment technologies are effective for organic load reduction, they often fail to remove recalcitrant xenobiotics such as pharmaceuticals, synthetic dyes, endocrine disruptors (EDCs), and microplastics (MPs). Engineered microbial consortia offer a promising and sustainable alternative owing to their metabolic flexibility, ecological resilience, and capacity for syntrophic degradation of complex pollutants. This review critically examines emerging strategies for enhancing microbial bioremediation in wastewater treatment systems (WWTS), focusing on co-digestion, biofilm engineering, targeted bioaugmentation, and incorporation of conductive materials to stimulate direct interspecies electron transfer (DIET). This review highlights how multi-omics platforms, including metagenomics, transcriptomics, and metabolomics, enable high-resolution community profiling and pathway reconstructions. The integration of artificial intelligence (AI) and machine learning (ML) algorithms into bioprocess diagnostics facilitates real-time system optimization, predictive modeling of antibiotic resistance gene (ARG) dynamics, and intelligent bioreactor control. Persistent challenges, such as microbial instability, ARG dissemination, reactor fouling, and the absence of region-specific microbial reference databases, are critically analyzed. This review concludes with a translational pathway for the development of next-generation WWTS that integrate synthetic microbial consortia, AI-mediated biosensors, and modular bioreactors within the One Health and Circular Economy framework.</p>","PeriodicalId":42356,"journal":{"name":"Journal of Xenobiotics","volume":"15 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12387628/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144973255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SAR-treated groups exhibited a significant increase in locomotor activity and a decrease in anxiety-like behavior, indicated by a reduction in time spent in one square and an increase in total movement time. Additionally, the histopathological findings greatly supported the biochemical results evidenced by stopping the detrimental effects caused by 5-FU through structural and functional alterations of cardiac tissues manifested as ameliorating congestion, inflammation, degeneration, arterial wall thinning, and endothelial loss. The dual-acting PPAR agonist SAR demonstrated cardiac protection activity, particularly the high dose, by attenuating cardiac-specific and nonspecific injury biomarkers along with anti-inflammatory and antioxidant activities and attenuated anxiety induced by 5-FU.

This review aims to explore the multifaceted consequences of antibiotic use in poultry production, with particular emphasis on the growing challenge of antimicrobial resistance (AMR). Evidence demonstrates that antibiotic use affects the gut microbiome, often resulting in long-lasting decreased diversity and restructuring of the bacterial communities. Moreover, consequences extend to the surrounding environment, including the airborne microbiome, water systems, and poultry litter, where alterations in microbial communities tend to be more subtle, whereas changes in genetic elements related to resistance are often more pronounced (drift). The emergence and persistence of resistance in these environments facilitate the spread of resistance genes across ecological boundaries, contributing to the broader dissemination of AMR.

Mice were treated with Uro-B (50 and 100 mg/kg) for four days and received ANIT (75 mg/kg) once on the second day. Our data revealed that Uro-B reduced elevated serum transaminases, alkaline phosphatase, lactate dehydrogenase, and total bilirubin levels associated with ANIT injection. Histopathologically, Uro-B effectively ameliorated ANIT-induced disruption of the hepatic architecture as represented by repressed necro-inflammation and bile duct proliferation. Uro-B also maintained oxidant/antioxidant status that was dysregulated by ANIT. Mechanistically, Uro-B markedly activated Kelch-like ECH-associated protein 1 (Keap-1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling with subsequent upregulation of hepatic heme oxygenase-1 expression. On the other hand, Uro-B suppressed the ANIT-induced expression of nuclear factor kappa-B (NF-κB), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6). Interestingly, Uro-B repressed peroxisome proliferator-activated receptor alpha (PPARα) expression in the liver. These findings indicate a promising hepatoprotective effect of Uro-B against ANIT-induced CLI in mice.

Specifically, the impact of DBP on the vascular reactivity after both rapid and 24 h DBP exposure was analyzed, as well as the contractility and the cell viability of vascular smooth muscle cells (VSMC).

However, the possible beneficial effect of LA on the toxicity of chemotherapy is currently unknown. The available evidence emphasizes the anticancer effect and mechanism of VCO and LA, and the VCO potential to combat adverse side effects of chemotherapy.
