title: Haloadaptation: salt sensing and cell-envelope changes.
abstract: When moderately halophilic bacteria adapt phenotypically to altered salinity, they modify the composition of their cell envelopes. These alterations are discussed in the context of how external salt concentration could be sensed and the adaptive changes triggered. A general model for salt sensing and signal transduction is suggested.
