Bacterial swarming is a rapid mass-migration, in which thousands of cells spread collectively to colonize surfaces. Physically, swarming is a natural example for active particles that use energy to generate motion. Accordingly, understanding the constraints physics imposes on these dynamics is essential for understanding the mechanisms underlying swarming. We present new experiments of swarming Bacillus subtilis mutants with different aspect ratios and at different densities; two physical… 

Physical characteristics of mixed-species swarming colonies.

In nature, bacterial collectives typically consist of multiple species, which are interacting both biochemically and physically. Nonetheless, past studies on the physical properties of swarming

Mechanistic underpinning of cell aspect ratio-dependent emergent collective motions in swarming bacteria.

Mechanical underpinning of the collective motions reveals that it is a joint venture of the short-range repulsive and the size-dependent motility forces, which determines the characteristics of swarming, which reinforces the mechanical interactions among neighboring cells leading to the overall fastest motion.

Heterogeneous bacterial swarms with mixed lengths.

The results suggest a physical advantage for the spontaneous heterogeneity of bacterial swarm populations, particularly around which aggregates of short, rapidly moving cells can form, resulting in enhanced swarming speeds.

Biophysical aspects underlying the swarm to biofilm transition

The experimental findings rule out previously suggested purely physical effects as a trigger for biofilm formation, and show how physical processes, such as clustering and jamming, accelerateBiofilm formation.

Surveying a Swarm: Experimental Techniques To Establish and Examine Bacterial Collective Motion

This minireview highlights aspects of swarming motility that differentiate it from other methods of bacterial locomotion, facilitatory mechanisms deployed by diverse bacteria to overcome different surface challenges, the approaches required to cultivate genuine swarmers, the methods available to observe and assess the various facets of this collective motion, and the features exhibited by the population as a whole.

Formation, collective motion, and merging of macroscopic bacterial aggregates

A novel process through which populations of bacteria cooperate and control the movement of large groups of cells is identified, identified and characterize a new mechanism for collective bacterial motility driven by a transient, density-dependent change in motility.

Swarming bacteria undergo localized dynamic phase transition to form stress-induced biofilms

A promising strategy of antibiotic treatment is proposed to effectively inhibit the transition from swarms to biofilms by targeting the localized phase transition using Bacillus subtilis, a model system for bacterial multicellularity.

Biofilm and swarming emergent behaviours controlled through the aid of biophysical understanding and tools

This minireview overviews recent studies unveiling physical and mechanical cues that trigger and affect swarming and biofilm development and focuses on cell shape, motion and density as the key parameters for mechanical cell–cell interactions within a community.

A mechanistic understanding of biofilm morphogenesis: Coexistence of mobile and sessile aggregates and phase-separated patterns

A particle-based biophyiscal model of bacterial cells and self-secreted extracellular polymeric substances (EPS) is developed to decipher the interplay of growth, motility-mediated dispersal, and mechanical interactions during microcolony morphogenesis and provides a significant understanding of the mechano-self-regulation during biofilm morphogenesis.

Cluster and conquer: the morphodynamics of invasion of a compliant substrate by active rods.

Furrow networks created by the active particles have a fractal-like structure whose dimension varies systematically with substrate stiffness but is less sensitive to particle activity, suggesting that, to sustain such extensive furrow networks, colonies must regulate their overall growth rate.



A statistical physics view of swarming bacteria

This review presents a physical point of view of swarming bacteria, with an emphasis on the statistical properties of the swarm dynamics as observed in experiments, and suggests a paradigm according to which bacteria have optimized some of their physical properties as a strategy for rapid surface translocation.

Effect of Cell Aspect Ratio on Swarming Bacteria.

It is shown that the swarming statistics depends on the aspect ratio in a critical, fundamental fashion not predicted by theory, which suggests that the robust mechanisms to maintain aspect ratios may be important for efficient swarming motility.

Collective motion and density fluctuations in bacterial colonies

This work reports simultaneous measurements of the positions, velocities, and orientations as a function of time for up to a thousand wild-type Bacillus subtilis bacteria in a colony, demonstrating that bacteria are an excellent system to study the general phenomenon of collective motion.

Learning the space-time phase diagram of bacterial swarm expansion

This work combines a high-throughput adaptive microscopy approach with machine learning, to identify key biological and physical mechanisms that determine distinct microscopic and macroscopic collective behavior phases which develop as Bacillus subtilis swarms expand over five orders of magnitude in space.

Emergence of macroscopic directed motion in populations of motile colloids

It is reported that dilute populations of millions of colloidal rolling particles self-organize to achieve coherent motion in a unique direction, with very few density and velocity fluctuations, in the polar-liquid state.

Dynamics of bacterial swarming.

Collective Motion of Spherical Bacteria

It is shown that the spherical motile bacteria Serratia marcescens exhibit robust collective dynamics and correlated coherent motion while grown in suspensions and opens a door for a new perspective on the role of cell aspect ratio and alignment of cells with regards to collective motion in nature.

Correlation properties of collective motion in bacterial suspensions

This work demonstrates the delicate balance between various physical mechanisms governing collective motion in bacterial suspensions and provides important insights into its mesoscopic nature and demonstrates that the particle shape is critical for the onset of collective effects.

Swarming bacteria migrate by Lévy Walk

By tracking trajectories of fluorescently labelled individuals within such dense swarms, it is found that the bacteria are performing super-diffusion, consistent with Lévy walks.

Swarming: Flexible Roaming Plans

The signature swirling and streaming motion within a swarm is an interesting phenomenon in and of itself, an emergent behavior with properties similar to flocking behavior in diverse systems, including birds and fish, providing a convenient new avenue for modeling such behavior.
