Temperature-dependent biofilm and sublancin production immobilise arsenic and antibiotic resistance gene mobility in soil system

This study shows that sublancin from Bacillus subtilis 168 reduces arsenic mobility and antibiotic resistance gene transfer in soil by forming temperature-dependent biofilms.

Molecular Insights Into PGPR-Biochar-Mediated Arsenic Detoxification and Nutritional Enhancement in Rice Rhizospheres

This study shows that combining rice biochar and PGPR reduces arsenic bioavailability and enhances rice growth in contaminated soils.

Furrow tillage reduces soil carbon loss and enhances microbial metabolism

This study introduces furrow tillage as a practice that reduces soil carbon loss and enhances microbial metabolism through a combination of agronomic, geochemical, and molecular analyses.

Subunit specialisation in AAA+ proteins and substrate unfolding during transcription complex remodelling

This study reveals the mechanism of DNA melting during transcription initiation by σ54-mediated open complex formation, showing how bEBP ATP hydrolysis drives σ54 unfolding and promoter DNA melting.

A model of Rtc-regulated RNA repair reveals heterogeneous responses to ribosome-targeting antibiotics and suggests molecular targets to potentiate their effects

The paper develops a computational model of Rtc-regulated RNA repair in E. coli, revealing cell-to-cell heterogeneity in antibiotic resistance and suggesting targets to enhance antibiotic efficacy.

GlnK facilitates the dynamic regulation of bacterial nitrogen assimilation

The paper investigates how GlnK and GlnB regulate glutamine synthetase activity in E. coli during nitrogen starvation and upshift using experiments and a biochemical model.
