Microbial herbicide degradation is an efficient bioremediation method. In this study, a strain of Streptomyces nigra, LM01, which efficiently degrades atrazine and nicosulfuron, was isolated from corn field using direct isolation The effects the identified on two herbicides were investigated optimized artificial neural network. maximum rates S. nigra LM01 58.09% 42.97% for respectively. rate in soil reached 67.94% when concentration 108 CFU/g after 5 d less effective than that nicosulfuron. Whole genome sequencing helped elucidate possible pathways protein sequences aligned with degraded proteins by National Center Biotechnology Information platform. sequence (GE005358, GE001556, GE004212, GE005218, GE004846, GE002487) highest query cover retained docked small-molecule ligands herbicides. results revealed binding energy −6.23 kcal/mol between GE005358 ligand −6.66 GE002487 nicosulfuron ligand. Atrazine are commonly used remain environment several hundred days. They often combination fields can cause severe damage to non-corn crops, including soybeans wheat. This phenomenon interferes crop rotation not conducive sustainable agriculture. soil, it degrading study elucidated mechanism detail, providing reference understanding environment.

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

Bacteria, Год журнала: 2025, Номер 4(1), С. 15 - 15

Опубликована: Март 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.

Nicosulfuron (NSR), a sulfonylurea herbicide, can easily enter water bodies, affecting aquatic life and human safety. Here, bacteria consortium YM2 was enriched domesticated from the active sludge of pesticide plant for bioremediation NSR wastewater. The response surface methodology data revealed that under optimal incubation conditions: 9.41 g L–1 maltodextrin, 21.37 yeast extract, 12.45 NaCl, degraded 97.49% within 4 d. degradation conditions were temperature 30°C, pH 6.0, inoculum 1%, initial concentration 20 mg L–1), system tolerant to heavy metal ions such as Cd2+, Pb2+, Ni2+, Zn2+ mainly occurred through bacterial extracellular enzymes (92.17%). Mechanistically, during process, reactive oxygen species, oxidative stress, cell membrane permeability, hydrophobicity, apoptosis rate first increased then decreased. Also, expression biofilm formation-related genes luxS, waaE, spo0A, wza varied with time concentration. wastewater soil 1.92 2.72 L–1, respectively. In simulated treatment unit (hydraulic retention 12 h), 84.55% after 10 This study provides theoretical basis microbial remediation NSR.
