Bacterial motility on a surface: many ways to a common goal.
TLDR
This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.Abstract:
When free-living bacteria colonize biotic or abiotic surfaces, the resultant changes in physiology and morphology have important consequences on their growth, development, and survival. Surface motility, biofilm formation, fruiting body development, and host invasion are some of the manifestations of functional responses to surface colonization. Bacteria may sense the growth surface either directly through physical contact or indirectly by sensing the proximity of fellow bacteria. Extracellular signals that elicit new gene expression include autoinducers, amino acids, peptides, proteins, and carbohydrates. This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.read more

Fimbriae and flagella mediated surface motility and the effect of glucose on nonpathogenic and uropathogenic Escherichia coli
Sankalya Ambagaspitiye,Sushmita Sudarshan,Jacob Hogins,Parker McDill,Nicole J. De Nisco,Philippe E. Zimmern,Larry Reitzer +6 more
TL;DR: Nonpathogenic and uropathogenic E. coli were shown to exhibit fimbriae- and flagella-dependent surface motility, respectively, and the difference was attributed to altered control of flageella synthesis by glucose.

Bacterial Adhesin Proteins Associated with Microbial Flocs and EPS in the Activated Sludge
TL;DR: Analysis of bacterial protein adhesins present in the extracellular polymeric substances (EPS), mainly those associated with pili, fimbriae, flagella, and curli, and to determine their role in microbial floc structure and function suggest that adhes Ins play an important role in initial floc formation.

Novel Method Reveals a Narrow Phylogenetic Distribution of Bacterial Dispersers in Environmental Communities Exposed to Low-Hydration Conditions.
TL;DR: A method to profile community dispersal and identify fast dispersers on a rough surface resembling soil surfaces and suggests that within the motile fraction of a bacterial community, only a minority of the bacterial types are able to disperse in the thinnest liquid films.

Bacterial-induced pH shifts link individual cell physiology to macroscale collective behavior
Veeramuthu Dharanishanthi,Amit Orgad,Neta Rotem,Efrat Hagai,Jeny Kerstnus-Banchik,Julius Ben-Ari,Tim Harig,Srinivasa Rao Ravella,Stefan Schulz,Yael Helman +9 more
TL;DR: In this article, a role for collective modifications of environmental pH carried out by microbial colonies living on a surface is presented, and it is shown that by collectively adjusting the local pH value, Paenibacillus spp. regulate their swarming motility.

Biofilms as complex differentiated communities.
TL;DR: It is submitted that complex cell-cell interactions within prokaryotic communities are an ancient characteristic, the development of which was facilitated by the localization of cells at surfaces, which may have provided the protective niche in which attached cells could create a localized homeostatic environment.

Flagellar and twitching motility are necessary for Pseudomonas aeruginosa biofilm development

TL;DR: The isolation and characterization of mutants of Pseudomonas aeruginosa PA14 defective in the initiation of biofilm formation on an abiotic surface, polyvinylchloride (PVC) plastic are reported and evidence that microcolonies form by aggregation of cells present in the monolayer is presented.
