Early stationary phase
WebStationary-phase definition: (chemistry) The solid or liquid phase of a chromatography system on which the materials to be separated are selectively adsorbed. WebMotility and chemotaxis allow cells to move away from stressful microenvironments. Motility of Escherichia coli in batch cultures, as measured by cell swimming speed, was low in early-exponential-phase cells, peaked as the cells entered post-exponential phase, and declined into early stationary phase.
