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

Casamino acids slow motility and stimulate surface growth in an extreme oligotroph.
TL;DR: The addition of 0.1 % CAA to minimal media significantly reduced the motility of YC1 after 72 hours, and inhibited swimming motility resulting in enhanced surface growth, which is proposed to be a physiological adaptation to oligotrophy, facilitating the colonization of nutrient rich environments.

TL;DR: A real time observation model, mimicking postoperative contamination, designed to follow E. coli proliferation on a titanium surface occupied by human osteoblastic progenitor cells (STRO) is developed, which shows that the surface colonization of bacteria is significantly enhanced on fibronectin coated surfaces irrespective of whether areas were uncovered or covered with human cells.

Novel non-flagellated surface motility mediated by chemical signaling in Citrobacter rodentium
TL;DR: A novel surface motility process is reported in C. rodentium QseC-mediated in this non-flagellated bacterium, and norepinephrine and ethanolamine act as environmental signals in this movement.
Nanoscopic vibrations by bacteria adhering to surfaces
TL;DR: The analysis of Brownian motion induced bacterial vibrations provides a novel, convenient and direct way to characterize the viscoelastic bond between the bacterium and the substratum.

Molecule gradient formation by mobile bio-nanomachines
TL;DR: Insight is gained into the process of molecule gradient formation, which is important in understanding biological systems and designing synthetic biological systems.

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.
