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

Biophysical processes supporting the diversity of microbial life in soil.
Robin Tecon,Dani Or +1 more
TL;DR: This review explores key drivers for microbial life in soils under different climates and land-use practices at scales ranging from soil pores to landscapes and delineates special features of soil as a microbial habitat and the consequences for microbial communities.

Antibiofilm and quorum sensing inhibitory potential of Cuminum cyminum and its secondary metabolite methyl eugenol against Gram negative bacterial pathogens
Issac Abraham Sybiya Vasantha Packiavathy,Palani Agilandeswari,Khadar Syed Musthafa,Shunmugiah Karutha Pandian,Arumugam Veera Ravi +4 more
TL;DR: The outcome of the present investigation reveals that C. cyminum extract strongly interferes with acyl homoserine lactone (AHL) regulated physiological functions coupled with biofilm formation such as flagellar motility and exopolysaccharide production.
Journal ArticleDOI
Cell density and mobility protect swarming bacteria against antibiotics
TL;DR: It is found that high densities promote bacterial survival, even in a nonswarming state, but that the ability to move, as well as the speed of movement, confers an added advantage, making swarming an effective strategy for prevailing against antimicrobials.

Tuned, driven, and active soft matter
TL;DR: In this article, a review of soft-matter systems that are quasi-statically tuned or switched to a new state by applying external external fields is presented, including those that are driven out of their ground state and out of equilibrium.

Colorimetric method for identifying plant essential oil components that affect biofilm formation and structure.
C. Niu,Eric S. Gilbert +1 more
TL;DR: The SBF assay could be useful as an initial step for finding plant essential oils and their components that affect biofilm formation and structure and indicated that there was reduced toxicity of the essential oil components to cells in biofilms compared to the toxicity to planktonic cells but revealed morphological damage to E. coli after cinnamaldehyde exposure.

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.
