A coevolution experiment reveals parallel mutations in the AcrA-AcrB-TolC efflux pump that contributes to bacterial antibiotic resistance

This study shows that coevolution between antibiotic-producing and antibiotic-sensitive bacteria leads to mutations in efflux pumps that enhance antibiotic resistance.

Bioactive exometabolites drive maintenance competition in simple bacterial communities

The paper shows that exometabolites from bacterial strains during stationary phase influence community outcomes through competitive interactions.

Exometabolite dynamics over stationary phase reveal strain-specific responses to nutrient limitation

This study examines exometabolite dynamics in three environmental bacteria during stationary phase, revealing strain-specific responses to nutrient limitation and metabolic reprogramming.
