Adaptation and niche construction by Pseudomonas fluorescens SBW25
… to as microcosms. Evolving populations of <i>Pseudomonas fluorescens</i> SBW25 in static microcosms reproducibly lead to the emergence of the Wrinkly Spreader (WS) genotype. These produce a cellulose-matrix-based biofilm to colonise the airliquid (A-L) interface with significant fitness …

Understanding microbial communities through horizontal gene transfer
… a simple co-culture of a model bacterium strain, Pseudomonas fluorescens SBW25, with sterile filtrate from garden compost cultures, and successfully observed the transfer of a previously uncharacterised class of mobile genetic elements (MGEs) into SBW25. Further experiments demonstrated that the …

Bacterial collectives
… heredity at the collective level. Populations of Pseudomonas fluorescens SBW25 provide a useful model: they readily evolve mat‑forming lineages at the air‑liquid interface in static microcosms. Although beneficial in the short term, these mats lack intrinsic group‑level reproduction. Their …

The impact of bacteria on the biophysics of water retention and flow in soil
… key components produced by the model organism, Pseudomonas fluorescens SBW25. Cellulose is an extracellular polysaccharide involved in the formation of the matrix of the bacterial biofilm, lipopolysaccharide is a cell membrane component required for bacterial attachment, and viscosin is a …

Understanding the eco-evolutionary dynamics underpinning changes in air-liquid interface biofilms in radiating populations and multi-species communities
… has been used to study adaptive radiation in Pseudomonas fluorescens SBW25, where non-biofilm forming wild-type populations diverge and biofilm-forming mutants known as Wrinkly Spreaders (WS) dominate the A-L interface where they are better able to exploit the ecological opportunity created by …
