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

Rectification of twitching bacteria through narrow channels: A numerical simulations study.
Konark Bisht,Rahul Marathe +1 more
TL;DR: In this paper, the authors numerically investigate the twitching motility in a two-dimensional corrugated channel and simulate the bacterial movement by two different models: (a) a detailed tug-of-war model which extensively describes the two-fingered motility of bacteria assisted by pili and (b) a coarse-grained run-and-tumble model which depicts the motion of wide-ranging self-propelled particles.

Ayixon Sánchez-Reyez,Ramón Alberto Batista-García,Gilberto Valdés-García,Ernesto Ortiz,Lucia Perezgasga,Andrés Zárate-Romero,Nina Pastor,Jorge Luis Folch-Mallol +7 more
TL;DR: A role for TE13 family thioesterases in swimming and degradation approaches for phenyl acetic acid is suggested in activated sludge, especially activities related with degradation of environmental pollutants.

Impact of confining 3-D polymer networks on dynamics of bacterial ingress and self-organisation
TL;DR: It is shown that Gram-positive and Gram-negative bacteria internally populate mesoporous polyacrylate hydrogels by quantifying: the dynamic advancing population front and the resultant spontaneous self-organisation into well-defined clusters and micro-colonies.

Biofilm Formation as Microbial Development
TL;DR: The results reviewed in this article indicate that the formation of biofilms serves as a new model system for the study of microbial development.

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
George A. O'Toole,Roberto Kolter +1 more
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.
