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.

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.

Periodic phenomena in Proteus mirabilis swarm colony development.
Oliver Rauprich,Mitsugu Matsushita,Cornelis J. Weijer,Florian Siegert,Sergei E. Esipov,James A. Shapiro +5 more
TL;DR: The data showed no connection between nutrient (glucose) depletion and the onset of different phases in swarm colony morphogenesis, and several observations point to the operation of density-dependent thresholds in controlling the transitions between distinct phases.

Intercellular Signaling During Fruiting-Body Development of Myxococcus xanthus
TL;DR: This review describes the current state of knowledge concerning cell-cell signaling during development and examines the social systems that guide fruiting body development through the isolation of conditional developmental mutants.

Glycopeptidolipid acetylation affects sliding motility and biofilm formation in Mycobacterium smegmatis.
Judith Recht,Roberto Kolter +1 more
TL;DR: A new mutant was obtained that resulted in partial inhibition of both processes and also showed an intermediate rough colony morphology in a screen for biofilm-defective mutants of Mycobacterium smegmatis mc(2)155.

Genetic Analysis of Sliding Motility in Mycobacterium smegmatis
TL;DR: A screen for nonsliding mutants of Mycobacterium smegmatis yielded 20 mutants with transposon insertions in the mps gene, which is involved in glycopeptidolipid biosynthesis, which lacked glycopepticolipids and were unable to form biofilms on polyvinyl chloride.

Type IV pili of pathogenic Neisseriae elicit cortical plaque formation in epithelial cells.
TL;DR: It is shown that type IV pili allow gonococci to overcome the inhibitory effect of heparin, a soluble receptor analogue, on gonococcal invasion of Chang and A431 epithelial cells, and a multistep model for neisserial colonization of mucosal epithelia is proposed.
