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.

Abstract. Pinontoan R, Susanto TSR, Lucy J, Angelina C, Soentoro SE, Purnomo JS, Cornelia M. 2024. Trypan blue dye decolorization by Aeromonas caviae isolated from water sewage in Jakarta, Indonesia. Biodiversitas 25: 1631-1637. The textile industry generates a substantial amount of hazardous chemical waste, which requires proper treatment to mitigate negative environmental and health consequences if left untreated. Studies on the removal Blue (TB), widely used commercial diazo dye, indigenous bacteria are limited. Therefore, this study aimed isolate, identify, characterize microorganisms capable decolorizing TB dye-contaminated wastewater Jakarta. Microorganisms were initially screened for activity solid media containing TB. Among strains, TB2 isolate exhibited highest potential was selected further analysis. morphological, biochemical, molecular, phylogenetic characteristics revealed that it belonged species caviae. To examine ability remove TB, various culture conditions, such as pH, temperature, agitation, tested. results demonstrated A. strain could reduce up 77.10% (0.0025% (w/v)) under static pH 7.0, 27°C over six days. our knowledge, is first report genus decolorize These imply use dye-bearing industrial wastewater.

Biosurfactants are ecofriendly substitutes for chemical surfactants. In this study, biosurfactant-producing bacterial strains were isolated from soil and water samples textile industry sites. Extracted biosurfactants could reduce the surface tension values 72 to 39.3 mN/m demonstrating that achieved critical micelle concentration. Stable emulsifications with diesel vegetable oil showed an emulsification index ranging 61.76% 76.47%. The presence of both rhamnolipid surfactin types was confirmed our isolates using FTIR, LC-MS/MS, GC-MS/MS analyses. These bacteria act on dyes heavy metals present in wastewater their concentrations by either degradation or biosorption. After reaction isolates, FTIR spectra breakdown some compounds conversion into intermediates. There also a reduction concentration effluents, as shown EDAX analysis. novel can be scaled up use reclamation recycled regular industrial use.

This study investigates the biodegradation of Reactive Red 141 (RR 141), an azo dye prevalent in textile industry, by bacteria isolated from activated sludge a effluent treatment plant. RR 141, characterized nitrogen–nitrogen double bonds (-N=N-), contributes to environmental issues when improperly disposed effluents, leading reduced oxygen levels water bodies, diminished sunlight penetration, and formation potentially carcinogenic mutagenic aromatic amines. research focuses on identifying with potential decolorize 141. Microbiological identification employs MALDI-TOF-MS, known for its precision rapid bacteria, enhancing efficiency. Results highlight Bacillus thuringiensis Kosakonia radicincitans as most promising strains decolorization. Analysis micro-organisms database exploration suggests correlation between these decolorization process. It is worth noting that this first report use K. Three distinct culture media—BHI, MSG, MS—were assessed investigate their impact Notably, BHI MSG media, incorporating carbon source, facilitated bacterial growth both tested species (B. radicincitans), phenomenon absent MS medium. observation exhibit limited capability utilize pointing towards influence medium discoloration The evaluates performance kinetics, capacity through UV-VIS spectrophotometry, degradation pathways via HPLC-MS analysis, phytotoxicity, enzymatic activity identification.
