  Abstract:  Saline environments are widely distributed in the world as a consequence of the geological steps in the evolution of the Earth. A lot of saline lakes and salt deposit are also found on the Romania territory, the most representative being Ursu Lake, complex of saline lakes in Slanic Prahova or Ocna Sibiului and Salt Lake (Braila County). The salt deposits on the Romania territory have geological age from the periods of Triassic (in Moesic platform – south of Romania) and Miocene (Transylvania and Maramures areas). Over 300 salt massifs were identified in- or extra-Carpathian areas and in some places (Slanic Prahova, Praid, Sarata Monteoru) piercing the Earth in the form of salt mountains (Ciobanu, 2002). This work will be focused on the main results obtained in our laboratories in last years and the main investigated saline ecosystems will be presented. The studies on the salt lake complex and from salt deposit from Slanic Prahova area conducted to the isolation of a novel haloarchaea strain, namely Haloferax prahovense and have highlighted some relationship between microbial composition in lakes and deposit. Recently investigated saline lake Letea, located inner Danube Delta revealed a seasonally variable salinity of this ecosystem which is reflected in microbial communities not only halophilic one, but also involved in main biogeochemical cycles of nitrogen and sulphur. On the other hand, the halophilic microorganisms belonging to Garicola genus have been isolated from so called „unusual habitat for halophiles”, namely mural painting from refectory of Hurezi Monastery.

Keywords: halophiles, pink coloration, saline ecosystem.
