This is the first study to explore the halotolerant soil microbiome of this region with culture-dependent methods.<\/p>\n<p>Forty-nine taxonomically diverse bacterial isolates were obtained from dry biological soil crust, surface soil and permafrost soil. Nine isolates were selected for whole genome sequencing; these genomes showed adaptations to their cold, saline native environment, such as cold shock proteins and a large number of osmoprotectant transporters.<\/p>\n<p>The genomes also contained several biosynthetic gene clusters, including a large variety of clusters involved in the production of antimicrobial compounds. Furthermore, most of the sequenced genomes showed low digital DNA-DNA hybridisation to their closest relatives, suggesting that they represent novel species.<\/p>\n<p>Overall, this study demonstrates the unexplored potential of High Arctic deserts as a source of novel halotolerant bacteria and their secondary metabolites.<\/p>\n<p><a href=\"https:\/\/www.biorxiv.org\/content\/10.1101\/2025.06.13.657406v2\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Genomic adaptations of novel halotolerant bacteria from extreme North Greenland<\/a>, biorxiv.org<\/p>\n<p>Astrobiology<\/p>\n<p>                                                                            <img decoding=\"async\" src=\"https:\/\/www.europesays.com\/dk\/wp-content\/uploads\/2026\/02\/keith_cowing.jpg\" alt=\"\"\/><\/p>\n<p>Explorers Club Fellow, ex-NASA Space Station Payload manager\/space biologist, Away Teams, Journalist, Lapsed climber, Synaesthete, Na\u2019Vi-Jedi-Freman-Buddhist-mix, ASL, Devon Island and Everest Base Camp veteran, (he\/him) \ud83d\udd96\ud83c\udffb<\/p>\n","protected":false},"excerpt":{"rendered":"Sampling sites at Kap K\u00f8benhavn (a) where permafrost soil samples were obtained at the erosion front left of&hellip;\n","protected":false},"author":2,"featured_media":26801,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[5],"tags":[649,17316,17317,17318,57,17319,17320,17321,17322,17323,17324],"class_list":["post-26800","post","type-post","status-publish","format-standard","has-post-thumbnail","category-greenland","tag-arctic","tag-away-team","tag-biorxiv-org","tag-dna","tag-greenland","tag-halotolerant","tag-https-astrobiology-com-2026-02-microbiology","tag-microbiome","tag-peary-land","tag-rna","tag-sample-return"],"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/posts\/26800","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/comments?post=26800"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/posts\/26800\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/media\/26801"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/media?parent=26800"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/categories?post=26800"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/tags?post=26800"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
