Once thought of extraordinary rarities, extremophiles became appealing gadgets for simple and utilized study starting from nanotechnology to biodiversity to the origins of existence or even to the hunt for extraterrestrial existence. a number of novel features of extremophiles are coated during this publication; the point of interest is to start with on strange and no more explored ecosystems resembling marine hypersaline deeps, severe chilly, barren region sands, and man-made fresh rooms for spacecraft meeting. Secondly, the more and more complicated box of functions from extremophile examine is taken care of and examples equivalent to novel psychrophilic enzymes, compounds from halophiles, and detection concepts for strength extraterrestrial existence varieties are presented.

4). In both brines the most abundant alkane is methane and the dissolved organic carbon (DOC) increases along with depth, indicating the presence of a subsurface DOC sink (Joye et al. 2009). 3 DHABs of the Eastern Mediterranean Sea The chemical composition of Urania, L’Atalante, Bannock and Discovery basins has been investigated extensively. All the hypersaline lakes show a distinct geochemistry, though Bannock, L’Atalante and Urania basins are more similar and signiﬁcantly different from Discovery (van der Wielen et al.
In particular, sequences belonging to the archaeal species Halorhabdus utahensis were not detected in seawater but strongly increased along the chemocline moving towards the brine, where they constituted up to the 33% of the total archaeal community. 8 M MgCl2 (Waino et al. 2000). The abundance of H. utahensis together with the high ectoenzymatic 31 Hypersaline extreme environments: geochemistry and microbiology activities and the low sulphate reduction and methane production occurring in Discovery brines, indicated that heterotrophic prokaryotes might play a major role than just that of being responsible for methanogenesis and sulphate reduction.
2008). These results indicate the potential role of dissolved extracellular DNA in hypersaline environments as a reservoir of genetic information that can be spread by HGT mediated by natural transformation. Hypersaline habitats represent a huge and still largely unknown source of biodiversity exploitable for biotechnological applications. Halophilic microorganisms produce a wide set of enzymes stable under conditions which would lead to denaturation of most proteins and which are commonly used during many industrial processes (Ventosa et al.
