Abstract The extraordinary metabolic flexibility of anoxygenic phototrophic purple non-sulfur bacteria (PNSB) has been exploited in the development various biotechnological applications, such as wastewater treatment, biohydrogen production, improvement soil fertility and plant growth, recovery high-value compounds. These versatile microorganisms can also be employed for efficient bioremediation hazardous inorganic organic pollutants from contaminated environments. Certain members PNSB, especially strains Rhodobacter sphaeroides Rhodopseudomonas palustris , exhibit remediation several toxic carcinogenic heavy metals metalloids, arsenic, cadmium, chromium, lead. PNSB are known to utilize diverse biomass-derived lignocellulosic compounds xenobiotics. Although biodegradation some substituted aromatic by established, available information on involvement is limited. In this review, we present advancements field PNSB-based pollutants. Furthermore, highlight that potential role a promising tool remains largely unexplored. Thus, review emphasizes necessity investing extensive research efforts technology.

Addressing nitrate contamination in water bodies is a critical environmental challenge, and Intimately Coupling Photocatalysis Biodegradation (ICPB) presents promising solution. However, there still debate about the effectiveness of ICPB reducing under hypotrophic conditions. Further research needed to understand its microbial metabolic mechanism functional changes bacterial structure. Here we explored mechanisms structure reactors integrating meticulously screened TiO2/g-C3N4 photocatalyst with biofilm. We achieved 26.3% increase reduction using 12.2% less organic carbon compared traditional biodegradation methods. Metagenomic analysis communities revealed evolving pathways conducive reduction. This not only elucidates photocatalytic behind conditions but also provides genomic insights that pave way for alternative approaches remediation technologies.

Type I semiconductor heterojunction BiOI/HKUST-1 composites were prepared through a solvothermal method, with optimisation of the molar ratio and reaction temperature. Comprehensive characterisation was conducted to assess physical chemical properties materials. These then evaluated for their ability activate persulfate (PMS) degrade high concentrations azo dye orange II (AO7) under visible light conditions. The influence various parameters, including catalyst dosage, PMS initial AO7 concentration, investigated. degradation followed pseudo-second order kinetic, irradiation 60 min, efficiency 94.9% achieved using dosage 0.2 g/L, concentration 0.5 mmol/L, an 200 mg/L. process involved synergistic action active species, O2−, 1O2, h+ playing pivotal role. Both BiOI HKUST-1 could be excited by light, leading generation photogenerated electron-hole pairs (e−-h+); can efficiently scavenge generated e−, enhancing separation rate e−-h+ subsequently improving AO7. findings highlight excellent photocatalytic BiOI/HKUST-1, making it promising candidate catalysing enhance dyes in environmental waters.
