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

Bacteria in Soil
TL;DR: Soils harbor many organisms, including many who can only be visualized with the aid of a microscope in all or parts of their life history, and their microenvironment, the type and quantity of nutrients and physicochemical properties, dictates much of their metabolic and evolutionary properties.

Effects of food surface topography on phage-based magnetoelastic biosensor detection
TL;DR: In this article, the authors investigated the effects of food surface topography on the detection capabilities of the phage-based magnetoelastic (ME) biosensors and found that small sensors could enhance detection capabilities.

TL;DR: In this article, the authors focus on various medical devices-associated biofilm infections that are affecting the host immune system leading to chronic infections and failure of the objective of this implant operation.

Using Experimental Evolution to Understand the Relationship between the Motile Strategies and Biosurfactant Production on a Nutrient Gradient, in Pseudomonas fluorescens.
TL;DR: It is shown that the evolved flagella mechanisms are far weaker than the wild-type system and thus the mutant bacteria rely on other motile secondary metabolites, particularly the biosurfactant viscosin, and a new novel swarming phenotype is introduced, which appears to be a combination of both smooth and spidery motility.
Dynamics of Microbial Growth and Coexistence on Variably Saturated Rough Surfaces
TL;DR: In this article, a new modeling framework was developed for the quantitative description of diffusion dominated microbial interactions focusing on competitive growth of two microbial species inhabiting partially saturated rough surfaces, where surface heterogeneity was repre- sented by patches with different porosities and water retention properties, yielding heterogeneous distribution of water contents that varies with changes in relative humidity or soil matric potential.

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.
