This study addresses existing gaps in understanding the specific involvement of dissolved organic matter (DOM) fractions antibiotic photolysis, particularly under natural conditions and during DOM photobleaching. Employing fluorescent, chemical, molecular analysis techniques, it explores impact extracellular intracellular (EOM IOM) on photodissipation multiclass antibiotics, coupled with photobleaching solar radiation. Key findings underscore selective fractions, propelled by distinct chemical profiles, influencing DOM-mediated photolysis. Notably, lipid-like substances dominate IOM, while lignin-like prevail EOM, each uniquely responding to sunlight exhibiting Sunlight primarily targets fulvic acid-like lignin components contrasting initial changes observed tryptophan-like lipid IOM. The lower photolability attributed its rich unsaturated compounds, contributes an enhanced rate indirect photolysis (0.339-1.402 h

The continuous release of greenhouse gases (GHG) is negatively affecting the sustainability ocean as a carbon sink via acidification and warming. capture storage GHGs important to reduce long-term effects emissions. use microalgae biofilms for GHG sequestration promising method due their ability adapt different environmental conditions rapid growth characteristics. current review shows how process biofilm nitrogen contributes economic sustainability. that wastewater medium cultivation cost effective will increase feasibility sequestration, but dynamic nature structure, which directly influenced by type substrate, liquid flow, conditions, limitation. results cannot assure highly economically viable using techno-economic analysis lack accessible data showing precise estimation operating expenditures capital expenditures. also lead because in availability bioresources caused decrease world's dependency on fossil resources.

Removal of PAHs in paddy fields: How natural periphytic biofilm enhances the removal process and the mechanisms involved

Environmental Technology & Innovation, Год журнала: 2024, Номер 33, С. 103533 - 103533

Previous studies on the removal of polycyclic aromatic hydrocarbons (PAHs) from farmland have mostly relied anthropogenic biotic or abiotic amendments. Here, an indigenous paddy periphytic biofilm (PB) composed complex symbolic communities was enriched, and its essential role, as well potential mechanisms PAHs dissipation, investigated. A pot experiment revealed that PB achieved 92.87% 92.76% USEPA priority overlying water soil a heavily PAHs-contaminated field, respectively. This subsequently decreased ΣPAHs accumulation in rice shoots to 4.12 ± 1.08 ng g-1, under thresholds based food safety standards. The physiology aquatic culture with assessed understand toxicity mechanism. Extracellular polymeric substances (EPS) adsorption occurred early stage, followed by late biodegradation, which considered primary mechanism for removing PAHs. In this process, contributed more high molecular weight compared low weight. Furthermore, 16S-rRNA sequencing demonstrated specific functional phyla (Proteobacteria, Ascomycota, Chloroplastida) significantly higher relative abundances PAHs, facilitated degradation. predicted synergetic metabolic pathway involved 33 PAHs-degrading genes inferred PICRUSt. These findings suggest could provide promising strategy target remediation situ contaminated fields.
