Strengthening biopolymer adhesives through ureolysis-induced calcium carbonate precipitation

Scientific Reports
Common adhesives for nonstructural applications are manufactured using petrochemicals and synthetic solvents. These adhesives are associated with environmental and health concerns because of their release of volatile organic compounds (VOCs).

BIOFILM REACTORS

, 2010
After presenting the concept of biofilms, reference is made to their importance in industry and health. Although biofilms are also well known for their deleterious effects (biofouling), emphasis is here given to the beneficial use of biofilms in wastewater treatment.

Mycobacterial Biofilms

Microbiology Spectrum, 2014
ABSTRACT Bacteria have a natural propensity to grow as sessile, matrix-encapsulated, multicellular communities called biofilms. Formation of biofilms proceeds through genetically programmed, distinct developmental stages signaled by intricate networks of communication among the constituent population and their environment ...

Identification and characterisation of two functional antibiotic MATE efflux pumps in the archaeon Halorubrum amylolyticum

npj Antimicrobials and Resistance
Multidrug efflux pumps have been found to play a crucial role in drug resistance in bacteria and eukaryotes. In this study, we investigated the presence of functional multidrug and toxic compound extrusion (MATE) efflux pumps, inferred from whole genome ...

Biofilm Formation and the Role of Efflux Pumps in ESKAPE Pathogens

Microorganisms
Nosocomial infections caused by ESKAPE pathogens represent a significant burden to global health. These pathogens may exhibit multidrug resistance (MDR) mechanisms, of which mechanisms such as efflux pumps and biofilm formation are gaining significant ...

The post-translational adaptor protein SadB modulates the pathogenicity of Pseudomonas aeruginosa

Journal of Bacteriology
In Pseudomonas aeruginosa, SadB acts as a post-translational adaptor protein that binds to the transcriptional regulator AmrZ. Deletion of sadB results in a biofilm-defective, hyperswarming phenotype. To investigate whether SadB contributes to virulence,

Potassium iodide enhances the antimicrobial activity of plasma-activated water

Biofilm
Plasma-activated water (PAW) is a promising disinfection strategy that generates a complex mixture of reactive oxygen and nitrogen species (ROS/RNS), including hydrogen peroxide (H2O2), nitrate (NO3−), and transient oxidants, in an acidic aqueous ...

The impact of antioxidant-ciprofloxacin combinations on the evolution of antibiotic resistance in Pseudomonas aeruginosa biofilms

npj Biofilms and Microbiomes
The evolution of antimicrobial resistance (AMR) in biofilms, driven by mechanisms like oxidative stress, is a major challenge. This study investigates whether antioxidants (AOs) such as N-acetyl-cysteine (NAC) and Edaravone (ED) can reduce AMR in ...
