Biofilms enhance rates of gene exchange, access to specific nutrients, and cell survivability. Haloarchaea in Deep Lake, Antarctica, are characterized by high rates of intergenera gene exchange, metabolic specialization that promotes niche adaptation, and are exposed to high levels of UV-irradiation in summer. Halorubrum lacusprofundi from Deep Lake has previously been reported to form biofilms...

Tuz Lake is the second biggest lake with an extreme hypersaline environment (over 32% (w/v) salt) in Turkey. It reported that was of marine origin, and its formation began tensional movements during Late Cretaceous Eocene. We conducted this research to determine prokaryotic diversity by metagenomics approach, which 16S rRNA amplicon sequencing microbial communities their natural environments. H...

BACKGROUND Archaeosomes (ARC), vesicles prepared from total polar lipids (TPL) extracted from selected genera and species from the Archaea domain, elicit both antibody and cell-mediated immunity to the entrapped antigen, as well as efficient cross priming of exogenous antigens, evoking a profound memory response. Screening for unexplored Archaea genus as new sources of adjuvancy, here we report...

The halophilic Archaeon Halorubrum lacusprofundi, isolated from the perennially cold and hypersaline Deep Lake in Antarctica, was recently sequenced and compared to 12 Haloarchaea from temperate climates by comparative genomics. Amino acid substitutions for 604 H. lacusprofundi proteins belonging to conserved haloarchaeal orthologous groups (cHOGs) were determined and found to occur at 7.85% of...

In vitro studies of the haloarchaeal genus Haloferax have demonstrated their ability to frequently exchange DNA between species, whereas rates of homologous recombination estimated from natural populations in the genus Halorubrum are high enough to maintain random association of alleles between five loci. To quantify the effects of gene transfer and recombination of commonly held (relaxed core)...
