Web1 de nov. de 2014 · As part of their life cycle, neutralophilic bacteria are often exposed to varying environmental stresses, among which fluctuations in pH are the most frequent. In particular, acid environments can be encountered in many situations from fermented food to the gastric compartment of the animal host. Webbacteria [4,9,10]. The advantage that chemotaxis confers on cells in such dynamic environments [1,11,12] may help explain why chemotactic responses to transient nutrient sources are so common among marine bacteria [5,6,8,10]. Although chemotaxis appears to be an important driver of bacterial compe- gold statue pngWebenvironments 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). gold statues birmingham

"WebMany chemotactic bacteria inhabit environments in which chemicals appear as localized pulses and evolve by processes such as diffusion and mixing. We show that, in such environments, physical limits on the accuracy of temporal gradient sensing govern when and where bacteria can accurately measure the cues they use to navigate.
