Electrical impedance spectroscopy with bacterial biofilms: neuronal-like behaviour

The paper demonstrates that E. coli biofilms exhibit negative capacitance at low frequencies in electrical impedance spectroscopy, similar to neuronal behavior, and links this to voltage-gated potassium channels.

Electrical Signalling in Three Dimensional Bacterial Biofilms Using an Agent Based Fire-Diffuse-Fire Model

The paper models electrical signaling in E. coli biofilms using a fire-diffuse-fire model, showing that wavefronts exhibit super-diffusive scaling and are influenced by geometry and ion diffusivity.

Working together to control mutation: how collective peroxide detoxification determines microbial mutation rate plasticity

This study identifies hydrogen peroxide detoxification as the mechanism behind density-dependent mutation rate plasticity in microbial populations.

Environmental and genetic influence on rate and spectrum of spontaneous mutations in Escherichia coli

This study investigates how environmental and genetic factors influence the mutation rate and spectrum in Escherichia coli, revealing distinct mutation patterns under different glucose conditions.

Emergence of ion-channel mediated electrical oscillations in E. coli biofilms

This study identifies ion-channel mediated electrical oscillations in E. coli biofilms, showing two hyperpolarization events in response to light stress and their role in long-range signaling.

Opposing effects of population density and stress on Escherichia coli mutation rate

This study shows that population density and stress have opposing effects on mutation rates in Escherichia coli, with mutation rates minimized at intermediate nutrient levels.
