WebMar 2, 2024 · Higher chemotactic motility was found in pH 7.0 media, compared with in pH 7.4 . Thus the chemotactic motility toward nutrition can be assumed to change colony morphology from volcano-like (pH 7.4) to crater-like (pH 7.0). The result also suggests that we can selectively and continuously regulate bacterial chemotaxis by making a slight pH ...

Webchemotactic: [adjective] involving, inducing, or exhibiting chemotaxis. WebNov 27, 2024 · The chemotactic rings of ∆ aer6 and ∆ aer234567 were approximately two-fold larger than that of the wild type. Chemotaxis of the ∆ aer4 mutant was inhibited notably. In contrast, bacteria were less chemotactic to potassium chloride, and the chemotactic ring diameter of the aer mutants were similar to that of the wild type (Figure 4C).
Chemotaxis (from chemo- + taxis) is the movement of an organism or entity in response to a chemical stimulus. Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.
