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 hydrodynamics of swimming microorganisms
Eric Lauga,Thomas R. Powers +1 more
TL;DR: The biophysical and mechanical principles of locomotion at the small scales relevant to cell swimming, tens of micrometers and below are reviewed, with emphasis on the simple physical picture and fundamental flow physics phenomena in this regime.

Bacillus subtilis antibiotics: structures, syntheses and specific functions
TL;DR: The structures of all known B. subtilis antibiotics are summarized, including non‐ribosomally produced lipopeptides are involved in biofilm and swarming development, lantibiotics function as pheromones in quorum‐sensing, and a ‘killing factor’ effectuates programmed cell death in sister cells.

Physics of microswimmers--single particle motion and collective behavior: a review.
TL;DR: The physics of locomotion of biological and synthetic microswimmers, and the collective behavior of their assemblies, are reviewed and the hydrodynamic aspects of swimming are addressed.

Physics of Microswimmers - Single Particle Motion and Collective Behavior
TL;DR: In this article, the authors review the physics of locomotion of biological and synthetic microswimmers, and the collective behavior of their assemblies, including synchronization and the concerted beating of flagella and cilia.

Natural functions of lipopeptides from Bacillus and Pseudomonas: more than surfactants and antibiotics
TL;DR: This review gives a detailed overview of the versatile functions of lipopeptides in the biology of Pseudomonas and Bacillus species, and highlights their role in competitive interactions with coexisting organisms, including bacteria, fungi, oomycetes, protozoa, nematodes and plants.

Sulfonolipids of gliding bacteria. Structure of the N-acylaminosulfonates.
TL;DR: Analysis by mass spectrometry and other methods revealed that most, if not all, of the aminosulfonates obtained by methanolysis were structurally identical to capnine, and the less polar sulfonolipids are predominantly N-fatty acyl capnines, 1-deoxy-1-sulfonic acid analogs of ceramides.

Swarming motility in Bacillus cereus and characterization of a fliY mutant impaired in swarm cell differentiation
Sonia Senesi,Francesco Celandroni,Sara Salvetti,Douglas J. Beecher,Amy C. L. Wong,Emilia Ghelardi +5 more
TL;DR: It is demonstrated that the activity of fliY is required for swarming and chemotaxis in B. cereus, and it is suggested that swarm-cell differentiation is coupled with virulence in this organism.

Type iii protein secretion in yersinia species.
TL;DR: What has been recently learned in yersiniae about the various environmental signals that induce type III secretion, how the synthesis of secretion substrates is regulated, and how such a diverse group of proteins is recognized as a substrate for secretion are reviewed.
Twelve pil Genes Are Required for Biogenesis of the R64
TL;DR: Kim et al. as discussed by the authors introduced frameshift mutations into each of the 14 pil genes to test their requirement for R64 thin pilus biogenesis, and they found that 12 genes, pilK to -V, are required for the formation of the thin pili.

Regulation of directed motility in myxococcus xanthus
Mandy J. Ward,David R. Zusman +1 more
TL;DR: The Frz signal‐transduction system regulates directed motility in M. xanthus and is essential for controlling both fruiting‐body development and vegetative swarming.
