Seeing new depths: Three-dimensional flow of a free-swimming alga
Gregorius Pradipta, Wanho Lee, Van Tran +8
A swimming microorganism stirs the surrounding fluid, creating a flow field that governs not only its locomotion and nutrient uptake, but also its interactions with other microorga…
Swimming patterns of a multi-mode bacterial swimmer in fluid shear flow
Valeriia Muraveva, Agniva Datta, Jeungeun Park +5
Bacterial swimming is well characterized in uniform liquids at rest. The natural habitat of bacterial swimmers, however, is often dominated by moving fluids and interfaces, resulti…
Flagellum Pumping Efficacy in Shear-Thinning Viscoelastic Fluids
Aaron Barrett, Aaron L. Fogelson, M. Gregory Forest +3
Microorganism motility often takes place within complex, viscoelastic fluid environments, e.g., sperm in cervicovaginal mucus and bacteria in biofilms. In such complex fluids, stra…
Bundling instability of lophotrichous bacteria
Jeungeun Park, Yongsam Kim, Wanho Lee +4
We present a mathematical model of lophotrichous bacteria, motivated by Pseudomonas putida, which swim through fluid by rotating a cluster of multiple flagella extended from near o…
