This study shows bacteria hyperpolarize when oxygen levels drop, linking membrane potential to oxygen stress and antibiotic susceptibility.

This study shows Bacillus subtilis biofilms use polymer composition to drive gel formation and morphological transitions through swelling and cross-linking.

This study shows that sporulation in Bacillus subtilis biofilms significantly affects viscoelastic properties more than matrix production, enhancing community-level physical stability.

This study shows that colony expansion and sporulation dynamics in Bacillus subtilis biofilms are interdependent, with sporulation waves driving dormancy while non-sporulating cells maintain expansion.

This study shows that motile and matrix-producing cells in Bacillus subtilis colonies drive distinct modes of cell-scale motion, with matrix-producing cells causing slow, ballistic movement.

This study uses an agent-based model to simulate metabolic signaling oscillations in Bacillus subtilis biofilms, showing how cellular properties drive collective behavior and nutrient distribution.

This paper introduces a non-optical, label-free electrical capacitance imaging method to image live microbial samples, enabling spatial and temporal resolution of microbial behavior in diverse environments.
