Published: May 30, 2023

The growing rate of urbanization and industrialization has led to an increase in several types pollution caused by the release toxic chemicals environment. This is usually perpetuated manufacturing industry (e.g. detergent dye), agricultural sectors fertilizers pesticides), mining cyanide sulphuric acid) construction companies cement metals). These pollutants have adverse effects on health plants, animals, humans. They also lead destruction microbial population both aquatic terrestrial regions, hence, necessitated need for remediation. Although different remediation methods, such as physical chemical been adopted years, however, drawbacks challenges associated with them promoted use alternative which bioremediation. Bioremediation involves using biological agents plants microbes remove or lessen environmental pollutants. Of two, are more utilized primarily because their rapid growth ability be easily manipulated, thus enhancing function Different groups bacteria, fungi algae employed clean up various review discusses types, mechanisms, factors affecting It recommends possible steps that could taken promote bioremediation agents.

Advancing Dye Degradation: Integrating Microbial Metabolism, Photocatalysis, and Nanotechnology for Eco-Friendly Solutions

Bacteria, Journal Year: 2025, Volume and Issue: 4(1), P. 15 - 15

Published: March 7, 2025

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.
