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

Design of nalidixic acid-vanadium complex loaded into chitosan hybrid nanoparticles as smart strategy to inhibit bacterial growth and quorum sensing
Bárbara Bueloni,Daniele Sanna,Eugenio Garribba,Guillermo R. Castro,Ignacio E. León,German Abel Islan +5 more
TL;DR: The V-NA complex proved to be a stronger antimicrobial agent against E. coli, B. cereus, S. aureus and P. aeruginosa than NA, based on inhibition experiments and results suggest that nanoparticles are suitable systems for drug delivery applications.

Influence of surface sub-micropattern on the adhesion of pioneer bacteria on metals.
TL;DR: Assessment of the early stages of Pseudomonas fluorescens biofilm formation on sub-microstructured surfaces that are in tune with bacterial size concluded that SMS influenced bacterial length, alignment, and distribution, whereas the chemistry of the surfaces affected bacterial length and distribution.

Entropy-driven motility of Sinorhizobium meliloti on a semi-solid surface
TL;DR: This work finds that unlike bacterial colonies that spread via bacterium-generated, physical propulsive forces, S. meliloti under quorum conditions may use EPS II to activate purely entropic forces within its environment, so that it can disperse by passively ‘surfing’ on those forces.

Phenotypic variation in Acidovorax radicisN35 influences plant growth promotion
Dan Li,Michael Rothballer,Marion Engel,Jonathan Hoser,Thorsten Schmidt,Christina Kuttler,Michael Schmid,Michael Schloter,Anton Hartmann +8 more
TL;DR: Acidovorax radicis N35, isolated from surface-sterilized wheat roots, showed irreversible phenotypic variation in nutrient broth, resulting in a differing colony morphology, and this mutation was consistent in all investigated phenotype variant cultures and might be responsible for the observed phenotypes.

Menaquinone and iron are essential for complex colony development in Bacillus subtilis.
TL;DR: It is demonstrated that both menaquinone and iron are essential for CCD in B. subtilis.

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

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.
