Batch cultures of                     N. maritimus                     grew well in concentrations of 0.1 to 1\uffe2\uff80\uff89mM NH                     4                     +                     and from 0.0001 to 1\uffe2\uff80\uff89mM I                     \uffe2\uff88\uff92                     . There was near 100% conversion of ammonium to nitrite over an 8\uffe2\uff80\uff90day growth period. No loss of I                     \uffe2\uff88\uff92                     or production of IO                     3                     \uffe2\uff88\uff92                     was detected in cultures where I                     \uffe2\uff88\uff92                     was added, indicating that                     N. maritimus                     is unable to drive I                     \uffe2\uff88\uff92                     oxidation under the tested conditions. This contrasts with previous observations of I                     \uffe2\uff88\uff92                     oxidation by ammonium oxidising bacteria (AOB). We explore whether differences between the metabolism of AOA and AOB could explain their differing actions on I                     \uffe2\uff88\uff92                     .                     N. maritimus                     cultures grown with the equivalent IO                     3                     \uffe2\uff88\uff92                     concentrations also showed no reduction in [IO                     3                     \uffe2\uff88\uff92                     ]. In addition, the growth of the                     N. maritimus                     culture was unaffected by inorganic iodine concentrations over 1000 times higher than in ambient seawater, suggesting a resilience to high iodine. These results suggest that AOA might have very little role in inorganic iodine turnover in the global ocean.                   </p", "keywords": ["ammonium", "iodate", "archaea", "oxidation", "iodide", "Nitrosopumilus maritimus", "nitrification", "Research Article"]}, "links": [{"href": "https://doi.org/10.1111/1758-2229.70168"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Environmental%20Microbiology%20Reports", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1111/1758-2229.70168", "name": "item", "description": "10.1111/1758-2229.70168", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1111/1758-2229.70168"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-08-01T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Nitrosopumilus+maritimus&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Nitrosopumilus+maritimus&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Nitrosopumilus+maritimus&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=Nitrosopumilus+maritimus&offset=1", "hreflang": "en-US"}], "numberMatched": 1, "numberReturned": 1, "distributedFeatures": [], "timeStamp": "2026-09-20T13:49:34.616626Z"}
