ABSTRACT This study determines organic-matter (OM) composition in the different color layers of a stratified hypersaline microbial mat and verifies hypothesis that each layer includes distinct group lipids. The relation precursor lipids from to hydrocarbon fossil records was also evaluated. To end, studied glycolipids (GLs), phospholipids (PLs), “neutral” (NLs, including hydrocarbons, n-alkanol...

Biofilm is the dominant habitat for aquatic microbes that can grow in various conditions, including environments with extreme conditions. One of conditions found ecosystems a hypersaline environment. As part biological resources, also live this However, although it predominant microbes, biofilms have yet to be widely explored. Understanding environments, especially salt ponds, will increase kno...

Microbiology of a hypersaline oil reservoir located in Central Africa was investigated with molecular and culture methods applied to preserved core samples. Here we show that the community structure was partially acquired during sedimentation, as many prokaryotic 16S rRNA gene sequences retrieved from the extracted DNA are phylogenetically related to actual Archaea inhabiting surface evaporitic...

The ability of euryhaline Mozambique tilapia to tolerate extreme environmental salinities makes it an excellent model for investigating iono-regulation. This study aimed to characterize and fill important information gap of the expression levels of key ion transporters for Na(+) and Cl(-) in the gill and esophageal-gastrointestinal tract of Mozambique tilapia acclimated to freshwater (0 ppt), s...

The fish brain plays an important role in controlling growth, development, reproduction, and adaptation to environmental change. However, few studies stem from the perspective of whole transcriptome change in a fish brain and its response to long-term hypersaline stress. This study compares the differential transcriptomic responses of juvenile Nile tilapia (Oreochromis niloticus) maintained for...

four halotolerant fungal isolates originating from the saltwater lake urmia in iran were selected during a screening program for salt resistance and α-amylase activity. the isolates were identified based on sequencing the its region and a part of the β-tubulin gene, as penicillium chrysogenum (isolate u1; cbs 132820), fusarium incarnatum (isolate u2; cbs 132821), and penicillium polonicum (isol...

Maras salterns are located 3,380 m above sea level in the Peruvian Andes. These salterns consist of more than 3,000 little ponds which are not interconnected and act as crystallizers where salt precipitates. These ponds are fed by hypersaline spring water rich in sodium and chloride. The microbiota inhabiting these salterns was examined by fluorescence in situ hybridization (FISH), 16S rRNA gen...

For a long time halotolerant and halophilic fungi have been known exclusively as contaminants of food preserved with high concentrations of either salt or sugar. They were first reported in 2000 to be active inhabitants of hypersaline environments, when they were found in man-made solar salterns in Slovenia. Since then, they have been described in different salterns and salt lakes on three cont...
