Spatial gradients and molecular transformations of DOM, DON and DOS in human-impacted estuarine sediments

Environment International, Journal Year: 2024, Volume and Issue: 185, P. 108518 - 108518

Published: Feb. 23, 2024

Dissolved organic matter (DOM) constitutes the most active fraction in global carbon pools, with estuarine sediments serving as significant repositories, where DOM is susceptible to dynamic transformations. Anthropogenic nitrogen (N) and sulfur (S) inputs further complicate by creating N-bearing (DON) S-bearing (DOS). This study delves into spatial gradients transformation mechanisms of DOM, DON, DOS Pearl River Estuary (PRE) sediments, China, using combined techniques UV-visible spectroscopy, Excitation-emission matrix (EEM) fluorescence Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), microbial high-throughput sequencing. Results uncovered a distinct gradient concentration, aromaticity (SUV

New Advances in Bioelectrochemical Systems in the Degradation of Polycyclic Aromatic Hydrocarbons: Source, Degradation Pathway, and Microbial Community

Energies, Journal Year: 2025, Volume and Issue: 18(1), P. 209 - 209

Published: Jan. 6, 2025

Because of their high persistence, polycyclic aromatic hydrocarbons (PAHs) are found in a wide range settings and pose health risk to both humans other organisms. Degradation PAHs is an essential part environmental management. By combining biological metabolism electrochemical processes, bioelectrochemical systems (BESs) can degrade provide important applications by converting the chemical energy pollutants into electrical for conversion recovery. This review provides comprehensive introduction PAH degradation BESs, including sources, effects performance enhancement methods, pathways, dominant microorganisms. focusing on relevant research recent years, main innovative focuses optimization configuration, electrode preparation, media additions improve removal PAHs. It demonstrates potential BESs field remediation, especially effectiveness treating difficult-to-degrade such as PAHs, concentrating application mechanism degradation. intended inexperienced reader with insight this area point out directions future research, design microbial community analysis.

Enhanced Soil Fertility and Carbon Sequestration in Urban Green Spaces through the Application of Fe-Modified Biochar Combined with Plant Growth-Promoting Bacteria

Biology, Journal Year: 2024, Volume and Issue: 13(8), P. 611 - 611

Published: Aug. 12, 2024

The soil of urban green spaces is severely degraded due to human activities during urbanization, and it crucial investigate effective measures that can restore the ecological functions soil. This study investigated effects plant growth promoting bacteria (Bacillus clausii) Fe-modified biochar on fertility increases mechanisms carbon sequestration. Additionally, C-cycling-related enzyme activity bacterial community were also explored. Six treatments included no or Bacillus clausii suspension added (CK), only (BC), (B), (FeB), combined with (BBC), (FeBBC). Compared other treatments, FeBBC treatment significantly decreased pH, alleviated alkalization, increased alkali-hydro nitrogen content in individual application FeB BC, improved aggregates’ stability positively function. compared organic (SOC), particulate (POC), inorganic (SIC) contents for FeBBC-treated by 28.46~113.52%, 66.99~434.72%, 7.34~10.04%, respectively. In treatment, improve physicochemical properties provide attachment sites, increase abundance diversity communities, promote uniform distribution carbon-related a single restoration method, sequestration, providing important reference values space restoration.
