How bacteria navigate varying environments
Webenvironments that wild bacteria navigate are often characterized by short-lived, microscale chemical gradients where background conditions are highly dilute (8, 9). In such ephemeral chemical fields, bacteria experience a gradient in DOM concentration as a noisy, dynamic signal, rather than as a steady concentration ramp (10). Web1 de fev. de 2008 · A simple family of models of a bacterial population in a time varying environment in which cells can transit between dormant and active states is constructed. It consists of a linear system of ordinary differential equations for active and dormant cells with time-dependent coefficients reflecting an environment which may be periodic or …
