Introduction: Fluid inclusion studies have the potential to record various important features of impact sites including the heating effects due to impact, hydrothermal fluid circulation history, the subsequent behavior of exposed rocks at the planetary surface and, of most interest to astrobiology, the preservation of organic matter [1, 2, 3]. “Water is of interest not only from the perspective...

Extreme halophilic archaea are a yet unexploited source of natural carotenoids. At elevated salinities, however, material corrosivity issues occur and the performance of analytical methods is strongly affected. The goal of this study was to develop a method for identification and downstream processing of potentially valuable bioproducts produced by archaea. To circumvent extreme salinities duri...

Background: D-Phenylglycine aminotransferase (D-PhgAT) is highly beneficial in pharmaceutical biotechnology. Like many other enzymes, D-PhgAT suffers from low stability under harsh processing conditions, poor solubility of substrate, products and occasional microbial contamination. Incorporation of miscible organic solvents into the enzyme’s reaction is considered as a solution...

Currently, the reduction of reactive dyes present in the textile effluent is a big challenge due to the threat to the environment. Existing physical and chemical methods contains many drawbacks. In the present scenario microbial reduction pays much attention and current focus of research. Therefore, the present study isolated dye decolorizing bacterium Exiguiobacterium aurantiacum (TSL7) from a...

The Smr family of multidrug transporters consists of small membrane proteins that extrude various drugs in exchange with protons rendering cells resistant to these drugs. Smr proteins identified to date have been found only in Eubacteria. In this work we present the cloning and characterization of an Smr protein from the archaeon Halobacterium salinarum, the first Smr in the archaeal kingdom. T...

Despite the wide interest in halophilic bacteria for practical and scientific reasons, very little has been done on their organic nutritional requirements, although their inorganic requirements have received considerable attention (Robinson, 1950; Schoop, 1935). Various complex media utilizing fish infusions (Gibbons, 1936; Harrison and Kennedy, 1922; Lochhead, 1934), beef and yeast extracts or...

BACKGROUND Extensive use of phenolic compounds in industry has resulted in the generation of saline wastewaters that produce significant environmental contamination; however, little information is available on the degradation of phenolic compounds in saline conditions. Halomonas organivorans G-16.1 (CECT 5995(T)) is a moderately halophilic bacterium that we isolated in a previous work from sali...
