Abstract The emergence of spatial organisation in biofilm growth is one of the most fundamental topics in biofilm biophysics and microbiology. It has long been known that growing biofilms can adopt smooth or rough interface morphologies, depending on

ABSTRACT In traditional models of in vitro biofilm development, individual bacterial cells seed a surface, multiply, and mature into multicellular, three-dimensional structures. Much research has been devoted to elucidating the mechanisms governing t

Distinct types of multicellular aggregates in Pseudomonas aeruginosa liquid cultures

Autor: Gavin melaugh, Vincent Martinez, Perrin Baker, Preston Hill, P. Lynne Howell, Daniel Wozniak, Rosalind Allen

Pseudomonas aeruginosa forms suspended multicellular aggregates when cultured in liquid media. Such aggregates may be important in disease, and/or as a pathway to biofilm formation. The polysaccharide Psl and extracellular DNA (eDNA) have both been i

Temperature-driven fluorescent NOT logic is demonstrated by exploiting predissociation in a 1,3,5-trisubstituted Δ 2 -pyrazoline on its own and when grafted onto silica microparticles. Related Δ 2 -pyrazolines become proton-driven YES and NOT logic

The Pseudomonas aeruginosa PSL polysaccharide is a social but non-cheatable trait in biofilms

Autor: Gavin Melaugh, Stuart A. West, Kasper Nørskov Kragh, Thomas Bjarnsholt, Rosalind J. Allen, Yasuhiko Irie, Vernita Gordon, Aled Edward Lloyd Roberts, Jaime Hutchison, Stephen P. Diggle

Extracellular polysaccharides are compounds secreted by microorganisms into the surrounding environment and which are important for surface attachment and maintaining structural integrity within biofilms. The social nature of many extracellular polys
