Quantitative characterization of run-and-tumble statistics in bulk bacterial suspensions
Yongfeng Zhao, Christina Kurzthaler, Nan Zhou +8
We introduce a numerical method to extract the parameters of run-and-tumble dynamics from experimental measurements of the intermediate scattering function. We show that proceeding…
Helical and oscillatory microswimmer motility statistics from differential dynamic microscopy
Ottavio A. Croze, Vincent A. Martinez, Theresa Jakuszeit +3
The experimental characterisation of the swimming statistics of populations of microorganisms or artificially propelled particles is essential for understanding the physics of acti…
Osmotaxis in Escherichia coli through changes in motor speed
Jerko Rosko, Vincent Martinez, Wilson Poon +1
Bacterial motility, and in particular repulsion or attraction towards specific chemicals, has been a subject of investigation for over 100 years, resulting in detailed understandin…
What is the 'minimum inhibitory concentration' (MIC) of pexiganan acting on Escherichia coli? - A cautionary case study
Alys K Jepson, Jana Schwarz-Linek, Lloyd Ryan +2
We measured the minimum inhibitory concentration (MIC) of the antimicrobial peptide pexiganan acting on Escherichia coli, and report an intrinsic variability in such measurements.…
Resonant alignment of microswimmer trajectories in oscillatory shear flows
Alexander Hope, Ottavio A. Croze, Wilson C. K. Poon +2
Oscillatory flows are commonly experienced by swimming microorganisms in the environment, industrial applications and rheological investigations. We experimentally characterise the…
Enhanced diffusion of nonswimmers in a three-dimensional bath of motile bacteria
A. Jepson, V. A. Martinez, J. Schwarz-Linek +2
We show, using differential dynamic microscopy, that the diffusivity of non-motile cells in a three-dimensional (3D) population of motile E. coli is enhanced by an amount proportio…
