Abstract
The role of the proton gradient and external pH in the motility and chemotaxis of Bacillus subtilis was investigated. Presence of a substantial proton gradient is not necessary for motility or chemotaxis, as long as the electrical potential is sufficient to maintain motility. Changes in the proton gradient do, however, lead to changes in swimming behavior, and these changes are mediated by two processes. One is sensitive to external pH and probably operates through a pH receptor. The second is sensitive to changes in the proton gradient. When the level of the protonmotive force is high enough to maintain motiligy, changes in the components of the protonmotive force are sensed by the bacteria and lead to behavioral changes, but changes in the protonmotive force are not necessary for chemotaxis.
摘要
研究了质子梯度和外部pH值在枯草芽孢杆菌运动性和趋化性中的作用。只要电势足以维持运动性，存在大量质子梯度对于运动性或趋化性并非必要。然而，质子梯度的变化确实会导致游泳行为的改变，并且这些变化由两个过程介导。一个对外部pH敏感，可能通过pH受体起作用。另一个对质子梯度的变化敏感。当质子动力势水平高到足以维持运动性时，细菌会感知质子动力势成分的变化并导致行为改变，但质子动力势的变化对于趋化性并非必要。
