Among other characteristics, these organisms produce cold-active enzymes with considerable biotechnological potential. The purpose of this study was to isolate and characterize bacteria from ice core samples collected on Horseshoe, Hovgaard, and Nansen Islands. Microorganisms from the latter two locations have been investigated only to a limited extent to date. Based on the phylogenetic analysis of 16S rRNA nucleotide sequences, eight bacterial isolates, including Sporosarcina, Arthrobacter, Bacillus, Luteimonas, Rhodococcus, and Methylobacterium were ultimately isolated and identified. Additionally, Raman and Fourier Transform Infrared Spectroscopy were used to analyze the biochemical properties of the bacteria. The bacterial culture\u2019s enzyme activity was assessed utilizing semiquantitative and screening techniques, and the API ZYM analysis revealed high enzyme activity, particularly for naphthol-AS-BI-phosphohydrolase, leucine aminopeptidase, esterase, lipase, and esterase. This study clarifies the biochemical characteristics of Antarctic bacteria and offers new perspectives on their enzymatic activity at various temperatures and resistance to antibiotics.<\/jats:p>","DOI":"10.1021\/acsomega.6c03982","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T17:01:46Z","timestamp":1786122106000},"page":"48099-48110","source":"Crossref","is-referenced-by-count":0,"title":["Psychrophilic Bacteria\nand Enzyme Activity in Antarctic\nIce Environments"],"prefix":"10.1021","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6681-0944","authenticated-orcid":true,"given":"Dilara","family":"Devecioglu","sequence":"first","affiliation":[{"name":"Istanbul Technical University , , , ,","place":["Maslak, Istanbul, Tu\u0308rki\u0307ye, 34449"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1514-7166","authenticated-orcid":true,"given":"Dilara Nur","family":"Dikmetas","sequence":"additional","affiliation":[{"name":"Istanbul Technical University , , , ,","place":["Maslak, Istanbul, Tu\u0308rki\u0307ye, 34449"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gamze","family":"Nes\u0327e-O\u0308zcan","sequence":"additional","affiliation":[{"name":"Istanbul Technical University , , , ,","place":["Maslak, Istanbul, Tu\u0308rki\u0307ye, 34449"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6576-0084","authenticated-orcid":true,"given":"Funda","family":"Karbancioglu Guler","sequence":"additional","affiliation":[{"name":"Istanbul Technical University , , , ,","place":["Maslak, Istanbul, Tu\u0308rki\u0307ye, 34449"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6201-6719","authenticated-orcid":true,"given":"Fatma Elif","family":"Genceli Gu\u0308ner","sequence":"additional","affiliation":[{"name":"Istanbul Technical University , , , ,","place":["Maslak, Istanbul, Tu\u0308rki\u0307ye, 34449"]},{"name":"Istanbul Technical University , , , ,","place":["Maslak, Istanbul, Tu\u0308rki\u0307ye, 34449"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"issue":"6496","key":"2026081811100024600_cit1","doi-asserted-by":"publisher","first-page":"1239","DOI":"10.1126\/science.aaz5845","article-title":"Pervasive Ice Sheet\nMass Loss Reflects Competing Ocean and Atmosphere Processes","volume":"368","author":"Smith","year":"2020","journal-title":"Science"},{"issue":"22","key":"2026081811100024600_cit2","doi-asserted-by":"publisher","first-page":"6483","DOI":"10.1111\/gcb.16356","article-title":"Emerging Biological\nArchives Can Reveal Ecological and Climatic Change in Antarctica","volume":"28","author":"Strugnell","year":"2022","journal-title":"Glob.
