Strain M27-SA2 was isolated from the deep-sea salt-saturated anoxic lake Medee, which represents one of the most hostile extreme environments on our planet. On the basis of physiological studies and phylogenetic positioning this extremely halophilic euryarchaeon belongs to a novel genus  ‘Halanaeroarchaeum’  within the family  Halobacteriaceae . All members of this genus cultivated so far are strict anaerobes using acetate as the sole carbon and energy source and elemental sulfur as electron acceptor. Here we report the complete genome sequence of the strain M27-SA2 which is composed of a 2,129,244-bp chromosome and a 124,256-bp plasmid. This is the second complete genome sequence within the genus  Halanaeroarchaeum.  We demonstrate that genome of ‘ Halanaeroarchaeum sulfurireducens’  M27-SA2 harbors complete metabolic pathways for acetate and sulfur catabolism and for  de novo  biosynthesis of 19 amino acids. The genomic analysis also reveals that  ‘Halanaeroarchaeum sulfurireducens’  M27-SA2 harbors two prophage loci and one CRISPR locus, highly similar to that of Kulunda Steppe (Altai, Russia) isolate ‘ H. sulfurireducens’  HSR2 T . The discovery of sulfur-respiring acetate-utilizing haloarchaeon in deep-sea hypersaline anoxic lakes has certain significance for understanding the biogeochemical functioning of these harsh ecosystems, which are incompatible with life for common organisms. Moreover, isolations of  Halanaeroarchaeum  members from geographically distant salt-saturated sites of different origin suggest a high degree of evolutionary success in their adaptation to this type of extreme biotopes around the world.
