Adaptive Evolution Laws of Biofilm under Emerging Pollutant-Induced Stress: Community Assembly-Driven Structure Response

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(29), P. 10721 - 10732

Published: July 11, 2023

The widely used biofilm process in advanced wastewater treatment is currently challenged by numerous exotic emerging pollutants (EPs), and the underlying principle of challenge adaptive evolution laws under EP stress. However, there still a knowledge gap exploration theory. Herein, we comprehensively analyzed morphological variation, community succession, assembly mechanism biofilms to report their sulfamethoxazole carbamazepine stress for first time. ecological role dominant species was driven as pioneer hub stress, deterministic processes indicated functional basis transformation. In addition, characteristic responses dispersal limitation homogenizing adequately revealed pathways resulting structural variation. Therefore, "interfacial exposure-structural variation-mass transfer feedback" inferred underly biofilms. Overall, this study highlighted internal drivers at phylogenetic level deepened our understanding development purification.

Emerging Issues and Initial Insights into Bacterial Biofilms: From Orthopedic Infection to Metabolomics

Antibiotics, Journal Year: 2024, Volume and Issue: 13(2), P. 184 - 184

Published: Feb. 13, 2024

Bacterial biofilms, enigmatic communities of microorganisms enclosed in an extracellular matrix, still represent open challenge many clinical contexts, including orthopedics, where biofilm-associated bone and joint infections remain the main cause implant failure. This study explores scenario biofilm infections, with a focus on those related to orthopedic implants, highlighting recently emerged substantial aspects pathogenesis their potential repercussions clinic, as well progress gaps that exist diagnostics management these infections. The classic mechanisms through which biofilms form more proposed new ones are depicted. ways bacteria hide, become impenetrable antibiotics, evade immune defenses, creating reservoirs difficult detect reach, delineated, such bacterial dormancy within entry into host cells, penetration canaliculi. New findings formation components presented. article also delves emerging critical concept immunometabolism, key function cells interferes with. growing metabolomics diagnosis therapy is highlighted, referring latest research.

MoS₂ Nanosheets Anchored onto MIL-100(Fe)-Derived FeS₂ as a Peroxymonosulfate Activator for Efficient Sulfamethoxazole Degradation: Insights into the Mechanism

ACS ES&T Water, Journal Year: 2022, Volume and Issue: 3(1), P. 213 - 226

Published: Dec. 15, 2022

By anchoring MoS2 nanosheets onto FeS2 derived from different MIL-100(Fe) precursors, a series of FeS2@MoS2-x samples featuring sulfur vacancies (SVs) were prepared as efficient peroxymonosulfate (PMS) activators to degrade sulfamethoxazole (SMX) aqueous solution. Benefiting the strongly reductive species (S2– and S22–), enriched Mo(IV) sites, abundant SVs, 40 μM SMX was completely removed by FeS2@MoS2-2/PMS system in 7 min (0.2 g/L FeS2@MoS2-2, 0.25 mM PMS). The kobs obtained FeS2@MoS2-2 0.598 min–1, which 5.8 51.1 times higher than that (0.103 min–1) (0.012 min–1), respectively. Quenching experiments, electron paramagnetic resonance (EPR) analysis, 18O isotope labeling tests evidenced involvement radical (•OH, SO4•–) non-radical (1O2, FeIV = O) pathways system, enormously enhanced contribution non-radicals 45.5%. In addition, SVs possessed favorable affinity toward PMS dissolved oxygen (DO), promoting continuous production reactive active species. degradation unveiled well. satisfactory recyclability, stability, universality enabled serve promising candidate for activation. This study provides novel strategy construct vacancy-featuring Fe-based sulfide catalysts using sacrificial templates activating treat refractory organic-polluted water.
