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

The Role of Biosurfactants in Bacterial Systems
TL;DR: The complex biochemistry inside bacterial systems results in the production of several species of molecules with complex composition and architecture, which are often surface active agents, or surfactants in short, as produced by bacterial systems such as Bacillus subtilis, Escherichia coli, Rhizobium etli, Proteus mirabilis and rhamnolipids in Pseudomonas aeruginosa.

Growth and Attachment-Facilitated Entry of Bacteria into Submicrometer Pores Can Enhance Bioremediation and Oil Recovery in Low-Permeability and Microporous Media
TL;DR: Bioremediation end points for biodegradable hydrophobic compounds in soil aggregates are regulated by bacterial accessibility to different pore sizes by evaluating the accessibility of the nonmotile hydrocarbon-degrading bacterium Dietzia maris to 0.4 μm pores.

Single Nanoparticle Tracking Reveals Efficient Long-Distance Undercurrent Transport in Upper Fluid of Bacterial Swarms
TL;DR: Gold nanorods (AuNRs) are used as single particle tracers to explore the spatiotemporal structure of the swarm fluid, revealing efficient fluidic flows above the swarms that provide obstacle-free highways for long-range material transportations and imply the essential role of the fluid phase on the emergence of large-scale synergy.

RssAB Signaling Coordinates Early Development of Surface Multicellularity in Serratia marcescens
Yu-Huan Tsai,Jun-Rong Wei,Chuan-Sheng Lin,Po-Han Chen,Stella Huang,Yu-Ching Lin,Chia-Fong Wei,Chia-Chen Lu,Hsin-Chih Lai +8 more
TL;DR: Monitoring the RssAB signaling status within single cells by tracing the location of the translational fusion protein EGFP-RssB following development of swarming or biofilm formation contributes to an improved understanding of how bacteria coordinate their lifestyle on a surface.

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.
