Compatible solutes, ionic stress, salt
Halotolerance is tolerance to ionic stress, or the ability of an organism to grow at salt concentrations higher than those required for growth. Halotolerant organisms are able to survive at high salt concentrations but do not require these conditions for growth.
Halotolerance is a relative term that refers to the ability to survive or thrive at salt concentrations higher than those necessary for growth. A microorganism is considered extremely halotolerant if its growth range extends above 2.5 M salt. A 0.9% NaCl would be considered an isotonic solution by most nonmarine and non-halophilic organisms. In nature, halotolerant organisms can be found in settings such as saline waters and soils that are inhabited by autochthonous halophilic microbiota, or even in association with animals. Such is the case of microbiota such as Staphylococcusspecies that live on human skin. Because of their...
