Hypersaline environments are widely distributed on the earth s continent where they exist either as natural water bodies such as permanent saline lakes, ephemeral saltpans and salt marshes,or as artificial solar salterns (Litchfield and Gillevet; 2002). The microbial diversity of saline lakes has been studied primarily by focusing on the isolation and characterization of individual organisms wi...

Coastal photosynthetic microbial mats are highly structured microbial communities that populate a variety of shallow environments such as estuaries, sheltered sandy beaches, intertidal flats, salt marshes and hypersaline salterns. In soft sediments, most of these microbial mats are formed of vertically stratified, multicolored cohesive thin layers, of several functional groups of microorganisms...

The mineral composition of the microbial mats at La Banya spit was studied. The spit is formed by a narrow sand bar and a peninsula and is located south of the main body of the Ebro Delta (Tarragona, Spain). Although quartz was the predominant mineral component in all sampling sites, clay, feldspars, calcite, aragonite, halite, dolomite and gypsum were also found. An increase in both the fine m...

Haloarchaea are the predominant microflora of hypersaline econiches such as solar salterns, soda lakes, and estuaries where the salinity ranges from 35 to 400 ppt. Econiches like estuaries and solar crystallizer ponds may contain high concentrations of metals since they serve as ecological sinks for metal pollution and also as effective traps for river borne metals. The availability of metals i...

The American brine shrimp Artemia franciscana Kellogg, 1906 is invasive in the Mediterranean region where it has displaced native populations of sexual A. salina and clonal A. parthenogenetica from many hypersaline wetlands. Brine shrimps are intermediate hosts of several cyclophyllidean avian cestodes, whose effects have been studied in native Artemia. However, determinants of these infections...

A novel, alkali-tolerant halophilic bacterium-OKH with an ability to produce extracellular halophilic, alkali-tolerant, organic solvent stable, and moderately thermostable xylanase was isolated from salt salterns of Mithapur region, Gujarat, India. Identification of the bacterium was done based upon biochemical tests and 16S rRNA sequence. Maximum xylanase production was achieved at pH 9.0 and ...
