Interaction of acetamiprid with extracellular polymeric substances (EPS) from activated sludge: A fluorescence study

, 2010
Extracellular polymeric substances (EPS) are important components of activated sludge and it plays an important role in removing pollutants. The interaction between EPS and organic pollutants is still little known.

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Integrated Capsaicin‐Functionalized Superhydrophobic Photothermal Coating for Sustainable Antifouling Control at the Air‐Seawater Interface

Small, EarlyView.
An integrated capsaicin‐functionalized superhydrophobic photothermal coating combines covalently immobilized bioactive functionality and Cassie‐state anti‐adhesion with CNT‐enabled solar heating. This dual‐mode strategy passively suppresses fouling in the dark and promotes photothermal inactivation and detachment under sunlight, delivering broad ...

A Cytoplasmic pH Sensor Redefines Gating in Bacterial Urea Channels and Acid Resistance

Small, EarlyView.
Bacterial survival in acidic environments requires pH‐gated urea channels. Utilizing complementary approaches, we identify a conserved cytoplasmic glutamic acid residue as a pH sensor in UreI channels. Whereas Gram‐positive bacteria rely solely on this sensor, Gram‐negative bacteria employ a dual‐sensor mechanism with periplasmic residues, revealing a ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.
