In the present study, nine species of Aspergillus, viz., A. alliaceus, A. ochraceus, A. persii, A. leproris, A. parasiticus, A. fumigatiaffinis, A. sydowii, A. niger, A. tubingensis and Eurotium amstelodami were obtained and identified from soils of the National Park of Urmia Lake, based on cultural and morphological characteristics. All of the species are newly recorded from hypersaline soils ...

Previous investigations of the salinity effects on the microbial community composition have largely been limited to dynamic estuaries and coastal solar salterns. In this study, the effects of salinity and mineralogy on microbial community composition was studied by using a 900-cm sediment core collected from a stable, inland hypersaline lake, Lake Chaka, on the Tibetan Plateau, north-western Ch...

Abstract The Urmia Lake National Park (NW Iran) represents a unique ecosystem owing to special ecological conditions prevailing the region. The Urmia Lake National Park comprises a range of normal to extreme environments, with variable range of salinity between 120-300 g/L. The present study was aimed to characterize ascomycetous yeast mycobiota inhabiting hypersaline soils in this region. Soi...

Spatial measurements of conductivity, temperature and depth were used to study salinity variations along the principal channels of the tidal hypersaline creek network in the vicinity of Bushehr Port, Persian Gulf during three 25- tidal cycles in both warm and cold months. Salinity variations and tidal fluctuations were out of phase throughout the short inverse estuary. The salinity values in...

The extremely acidic brine lakes of the Yilgarn Craton of Western Australia are home to some of the most biologically challenging waters on Earth. In this study, we employed metagenomic shotgun sequencing to generate a microbial profile of the depositional environment associated with the sulfur-rich sediments of one such lake. Of the 1.5 M high-quality reads generated, 0.25 M were mapped to pro...

Numerous lineage-specific expansions of the transcription factor B (TFB) family in archaea suggests an important role for expanded TFBs in encoding environment-specific gene regulatory programs. Given the characteristics of hypersaline lakes, the unusually large numbers of TFBs in halophilic archaea further suggests that they might be especially important in rapid adaptation to the challenges o...

Plasma membrane Mg2+, Ca2+ ATPases were isolated from Dunaliella parva by differential centrifugation and subsequent sucrose gradient centrifugation and analyzed for their properties with special emphasis on ecophysiological requirements of this extremely salt-tolerant alga. Most properties (Vmaxand AfM-values, substrate specificity, vanadate and DES sensitivity, resistance against ouabain) ind...
