Here, we used laboratory incubations to determine the potential impact of their activity on the cycling of iron (Fe), phosphorus (P) and sulfur (S). Microsensor depth profiles of oxygen, sulfide and pH in combination with electric potential profiling and fluorescence in situ hybridisation (FISH) analyses showed a rapid development (<span class=\"inline-formula\">&lt;5</span> d) of cable bacteria, followed by a long period of activity (<span class=\"inline-formula\">&gt;200</span> d). During most of the experiment, the current density correlated linearly with the oxygen demand. Sediment oxygen uptake was attributed to the activity of cable bacteria and the oxidation of reduced products from the anaerobic degradation of organic matter, such as ammonium. Pore water sulfide was low (<span class=\"inline-formula\">&lt;</span> 5 <span class=\"inline-formula\">µ</span>M) throughout the experiment. Sulfate reduction acted as the main source of sulfide for cable bacteria. Pore water Fe<span class=\"inline-formula\"><sup>2+</sup></span> reached levels of up to 1.7 mM during the incubations, due to the dissolution of FeS (30 %) and siderite, an Fe carbonate mineral (70 %). Following the upward diffusion of Fe<span class=\"inline-formula\"><sup>2+</sup></span>, a surface enrichment of Fe oxides formed. Hence, besides FeS, siderite may act as a major source of Fe for Fe oxides in coastal surface sediments where cable bacteria are active. Using <span class=\"inline-formula\">µ</span>XRF, we show that the enrichments in Fe oxides induced by cable bacteria are located in a thin subsurface layer of 0.3 mm. We show that similar subsurface layers enriched in Fe and P are also observed at field sites where cable bacteria were recently active and little bioturbation occurs. This suggests that such subsurface Fe oxide layers, which are not always visible to the naked eye, could potentially be a marker for recent activity of cable bacteria.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biogeochemical impact of cable bacteria on coastal Black Sea sediment","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-05-17","DateCreate":"2021-02-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000596664400001","VABBcode":null,"OpenAcc":1,"DOI":"10.5194/bg-17-5919-2020"},"refs":null,"anarec":{"AnaID":333509,"PubliDate":2020,"Pagination":"5919-5938","XtraPublOfAnaID":null,"ISBN":null,"Volume":"17","Issue":"23","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":68092,"SerRR":"<b>Gattuso, J.P.; Kesselmeier, J.
