Sporulation modulates viscoelastic development through extracellular matrix restructuring in Bacillus subtilis biofilms

Biofilm formation–the establishment of cellular communities within a self-secreted polymer matrix–is a behavior exhibited by almost all species of bacteria. Bacterial biofilms are well described as viscoelastic materials, with properties that grant physical advantages, such as elastic resilience and viscous adaptabilit...

Formation of a swelling gel underlies a morphological transition in Bacillus subtilis biofilms.

Microbes across diverse species and environments form biofilms, living materials composed of cells and extracellular polymers. Biofilm-dwelling cells benefit from emergent soft matter physics, which sculpts three-dimensional morphologies and facilitates osmotic nutrient uptake. Although biofilms are modeled as viscoela...
