Textile dyes pose a major environmental threat due to their toxicity, persistence in water bodies, and resistance conventional wastewater treatment. To address this, researchers have explored biological physicochemical degradation methods, focusing on microbial, photolytic, nanoparticle-mediated approaches, among others. Microbial depends fungi, bacteria, yeasts, algae, utilizing enzymatic pathways involving oxidoreductases like laccases, peroxidases, azoreductases breakdown or modify complex dye molecules. Photolytic employs hydroxyl radical generation electron-hole pair formation, while utilizes titanium dioxide (TiO2), zinc oxide (ZnO), silver (Ag) nanoparticles enhance removal. improve efficiency, microbial consortia been developed decolorization mineralization, offering cost-effective eco-friendly alternative methods. Photocatalytic degradation, particularly using TiO2, harnesses light energy for breakdown. Research advancements focus shifting TiO2 activation from UV visible through doping composite materials, optimizing surface area mesoporosity better adsorption. Nanoparticle-mediated approaches benefit high rapid adsorption, with ongoing improvements synthesis, functionalization, reusability, magnetic nanoparticle integration. These emerging technologies provide sustainable solutions degradation. The primary aim of this review is comprehensively evaluate synthesize current research the azo photolytic processes, nanotechnology-based approaches. also provides detailed information salient mechanistic aspects these efficiencies, advantages, challenges, potential applications industrial contexts.

With industrialization and widespread chemical use, soil organic pollutants have become a major environmental issue. Forest ecosystems, among the most important on Earth, unique potential for controlling remediating pollution. This article explores mechanisms of microbial community degradation pollutants, their adaptability across forest ecological conditions, effects factors efficiency. For example, acidic pH (pH < 5.5) favors PAH degradation, near-neutral (6.0–7.5) enhances pharmaceutical PPCP alkaline conditions > 7.5) facilitate petroleum hydrocarbon, VOC, breakdown. Optimal occurs with humidity levels between 60% 80%, SOM content 2–5%. review analyzes advancements in technologies ecosystem pollution treatment, including genetic engineering, composting, bioaugmentation, bio-stimulation techniques, integration phytoremediation. The also addresses challenges real-world implementation, such as maintaining diversity, managing pollutant complexity, adapting to changes, highlighting future research opportunities. next decade will focus synthetic biology, omics technologies, microbial-electrochemical systems, dynamics, eco-engineering, plant-microbe synergy develop efficient, sustainable bioremediation strategies.
