High salinity environments
WebHypersaline environments are considered extreme because normal cell physiologies cannot withstand the strong salt concentrations: the salinity gradient from inside to outside the … High salinity represents an extreme environment in which relatively few organisms have been able to adapt and survive. Most halophilic and all halotolerant organisms expend energy to exclude salt from their cytoplasm to avoid protein aggregation ('salting out'). To survive the high salinities, halophiles employ two differing strategies to prevent desiccation through osmotic movement of water out of their cytoplasm. Both strategies work by increasing the internal osmolarity of the cell…
