Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
A combination of structural, biochemical, single-molecule and in vivo methods are used to show how ParB locally condenses the bacterial chromosome near the origin and earmarks this region for segregation.
An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.
A 3D model captures the growth and expansion dynamics of bacterial colonies, revealing distinct effects of surface tension, mechanical forces, and nutrients on the speed of radial and vertical expansion.
The intracellular location of a key sulfur compound, dimethylsulfoniopropionate, was identified in microalgae and its subsequent uptake by marine bacteria was quantified using a combination of secondary-ion mass-spectrometry techniques.
