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 effect of temperature on the phenotypic features and the maceration ability of Dickeya solani strains isolated in Finland, Israel and Poland
TL;DR: Although D. solani strains from different climatic conditions have identical Pulse Field Gel Electrophoresis (PFGE) profiles in addition to the same fingerprint profiles obtained by the repetitive sequence-based polymerase chain reaction (REP, ERIC and BOX repetitive sequences), they differ in the examined phenotypic features, especially in the activities of pectinolytic, cellulolytic and proteolytic enzymes and their capacity to macerate potato tuber tissue.

Self-organization in bacterial swarming: lessons from myxobacteria
TL;DR: Recent efforts to understand how bacteria swarm are briefly reviewed, with integrated computational and experimental approaches, in addressing how order emerges in dense and initially disorganized populations of bacterial cells.

TL;DR: A new perspective is provided that NPs increase the risk of antibiotic resistance through MGEs during AD process, and ZnO NPs significantly reduced the microbial diversity and significantly changed the microbial community structure.

Surface motility of polycyclic aromatic hydrocarbon (PAH)-degrading mycobacteria.
Line Fredslund,Kristel Sniegowski,Lukas Y. Wick,Carsten S. Jacobsen,René De Mot,Dirk Springael +5 more
TL;DR: Surface motility of the polycyclic aromatic hydrocarbon (PAH)-degrading Mycobacterium gilvum VM552 was tested on agar and agarose plates prepared with varying amounts of gelling agents in the presence and absence of phenanthrene and it was suggested that formation of branches was the combined effect of cell division and growth at the tip of a branch and propulsion of cells from the mature basal parts of a Branch towards the tip.

Pseudomonads: a versatile bacterial group exhibiting dual resistance to metals and antibiotics.
TL;DR: Pseudomonads is a versatile and cosmopolitan bacterial group that can occur in metal contaminated as well as clinical environment and many of them possess the ability to proliferate resistance to bacteria from their own or other group.

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.

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.
