Lagoon ecosystems are particularly vulnerable to PAE pollution as they are semi-enclosed and receive high loads of organic materials. The present study investigates the distribution of seven common PAEs in three large European lagoons (Curonian, Vistula and Szczecin) in the southern Baltic Sea. The concentration levels of PAEs in the water column, encompassing both the dissolved and particulate-bound phases, and in sediments were assessed to elucidate distribution patterns and potential ecological risks within these lagoon ecosystems. The average concentration of total PAEs in the water column ranged from 0.03 to 1.45 \u03bcg L-1, whereas sediment concentration varied from 0.008 to 1.06 \u03bcg g-1, levels comparable to or lower than those found in other European coastal areas. Distribution patterns of PAEs in sediment showed notable similarity across all three lagoons, whereas variations were observed in the water column. Notably, di(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DOP) and dimethyl phthalate (DMP) emerged as the most concerning congeners in studied lagoons, all of which pose a moderate risk to aquatic organisms. This study applied shotgun transcriptomic analysis to field samples, revealing active microbial communities involved in PAEs degradation in the Baltic lagoons for the first time. The degradation of phthalic acid (PA) into intermediate compounds such as protocatechuate was not identified as a rate-limiting step in the studied environment. The degradation activity was primarily localized in the sediment layers, with Gram-negative bacteria playing a major role, while Gram-positive bacteria appeared incapable of degrading PA. These findings provide valuable insights into the distribution and transformation mechanisms of PAEs in estuarine environments.", "doi": "10.1016/j.scitotenv.2024.177526", "pmid": "39549755", "labels": {"NGI Stockholm (Genomics Production)": "Service", "National Genomics Infrastructure": "Service", "NGI Short read": "Service"}, "xrefs": [{"db": "pii", "key": "S0048-9697(24)07683-6"}], "notes": [], "created": "2025-01-02T10:30:52.543Z", "modified": "2025-04-07T07:29:33.765Z"}, {"entity": "publication", "iuid": "c6fef02079a649c1888d39e0943e5798", "links": {"self": {"href": "https://publications.scilifelab.se/publication/c6fef02079a649c1888d39e0943e5798.json"}, "display": {"href": "https://publications.scilifelab.se/publication/c6fef02079a649c1888d39e0943e5798"}}, "title": "Oxygen\u2010deficient water zones in the Baltic Sea promote uncharacterized Hg methylating microorganisms in underlying sediments", "authors": [{"family": "Capo", "given": "Eric", "initials": "E", "orcid": "0000-0001-9143-7061", "researcher": {"href": "https://publications.scilifelab.se/researcher/a4017e9c8167487b882ee2d045d96494.json"}}, {"family": "Broman", "given": "Elias", "initials": "E", "orcid": "0000-0001-9005-5168", "researcher": {"href": "https://publications.scilifelab.se/researcher/63826da04a1f4f80bc3229df12bac9b7.json"}}, {"family": "Bonaglia", "given": "Stefano", "initials": "S", "orcid": "0000-0003-4366-0677", "researcher": {"href": "https://publications.scilifelab.se/researcher/c02dd99f9fd14dd89d5c231260806720.json"}}, {"family": "Bravo", "given": "Andrea G", "initials": "AG", "orcid": "0000-0002-8341-3462", "researcher": {"href": "https://publications.scilifelab.se/researcher/749bb106ca6b452d82603ef8cf3cbdee.json"}}, {"family": "Bertilsson", "given": "Stefan", "initials": "S", "orcid": "0000-0002-4265-1835", "researcher": {"href": "https://publications.scilifelab.se/researcher/2c17765c2a9f4383b5383138d11ae93f.json"}}, {"family": "Soerensen", "given": "Anne L", "initials": "AL", "orcid": "0000-0002-8490-8600", "researcher": {"href": "https://publications.scilifelab.se/researcher/80c5602b03254dd6a9bee71d0429b678.json"}}, {"family": "Pinhassi", "given": "Jarone", "initials": "J", "orcid": "0000-0002-6405-1347", "researcher": {"href": "https://publications.scilifelab.se/researcher/b352d814c2534b06a79992fda3bbb075.json"}}, {"family": "Lundin", "given": "Daniel", "initials": "D", "orcid": "0000-0002-8779-6464", "researcher": {"href": "https://publications.scilifelab.se/researcher/227cc90e084348a193fee05eb23a6bf3.json"}}, {"family": "Buck", "given": "Moritz", "initials": "M", "orcid": "0000-0001-6632-5324", "researcher": {"href": "https://publications.scilifelab.se/researcher/ba68bf651630488dab4d146b11cf612a.json"}}, {"family": "Hall", "given": "Per O J", "initials": "POJ"}, {"family": "Nascimento", "given": "Francisco J A", "initials": "FJA", "orcid": "0000-0003-3722-1360", "researcher": {"href": "https://publications.scilifelab.se/researcher/5c2cfb0d7a614432b9dfdfcfa3fc4644.json"}}, {"family": "Bj\u00f6rn", "given": "Erik", "initials": "E", "orcid": "0000-0001-9570-8738", "researcher": {"href": "https://publications.scilifelab.se/researcher/d52d4c83dda84cea9e018199a8cfc304.json"}}], "type": "journal-article", "published": "2022-01-00", "journal": {"title": "Limnol Oceanogr", "issn": "0024-3590", "volume": "67", "issue": "1", "pages": "135-146", "issn-l": null}, "abstract": null, "doi": "10.1002/lno.11981", "pmid": null, "labels": {"Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [], "notes": [], "created": "2022-11-09T15:41:58.605Z", "modified": "2024-01-16T13:48:37.891Z"}, {"entity": "publication", "iuid": "f6f8f0ee5824415a8d8a54f6d2553b53", "links": {"self": {"href": "https://publications.scilifelab.se/publication/f6f8f0ee5824415a8d8a54f6d2553b53.json"}, "display": {"href": "https://publications.scilifelab.se/publication/f6f8f0ee5824415a8d8a54f6d2553b53"}}, "title": "High throughput shotgun sequencing of eRNA reveals taxonomic and derived functional shifts across a benthic productivity gradient.", "authors": [{"family": "Broman", "given": "Elias", "initials": "E", "orcid": "0000-0001-9005-5168", "researcher": {"href": "https://publications.scilifelab.se/researcher/63826da04a1f4f80bc3229df12bac9b7.json"}}, {"family": "Bonaglia", "given": "Stefano", "initials": "S", "orcid": "0000-0003-4366-0677", "researcher": {"href": "https://publications.scilifelab.se/researcher/c02dd99f9fd14dd89d5c231260806720.json"}}, {"family": "Norkko", "given": "Alf", "initials": "A"}, {"family": "Creer", "given": "Simon", "initials": "S"}, {"family": "Nascimento", "given": "Francisco J A", "initials": "FJA", "orcid": "0000-0003-3722-1360", "researcher": {"href": "https://publications.scilifelab.se/researcher/5c2cfb0d7a614432b9dfdfcfa3fc4644.json"}}], "type": "journal article", "published": "2021-07-00", "journal": {"title": "Mol.

These communities have traditionally been hard to sample and handle in the laboratory, but DNA sequencing has made such work less time consuming. While DNA sequencing captures both alive and dead organisms, environmental RNA (eRNA) better targets living organisms or organisms of recent origin in the environment. Here, we assessed the biodiversity of three known bioindicator microeukaryote groups (nematodes, foraminifera, and ciliates) in sediment samples collected at seven coastal sites along an organic carbon (OC) gradient. We aimed to investigate if eRNA shotgun sequencing can be used to simultaneously detect differences in (i) biodiversity of multiple microeukaryotic communities; and (ii) functional feeding traits of nematodes. Results showed that biodiversity was lower for nematodes and foraminifera in high OC (6.2%-6.9%), when compared to low OC sediments (1.2%-2.8%). Dissimilarity in community composition increased for all three groups between Low OC and High OC, as well as the classified feeding type of nematode genera (with more nonselective deposit feeders in high OC sediment). High relative abundant genera included nematode Sabatieria and foraminifera Elphidium in high OC, and Cryptocaryon-like ciliates in low OC sediments.

Viruses can therefore alter microbial diversity, community structure, and biogeochemical processes driven by these organisms. Cyanophages are viruses that infect and lyse cyanobacterial cells, adding bioavailable carbon and nutrients into the environment. Cyanobacteria are photosynthesizing bacteria, with some species capable of N2 fixation, which are known to form large blooms as well as resistant resting cells known as akinetes. Here, we investigated cyanophage diversity and community structure plus cyanobacteria in dead zone sediments. We sampled surface sediments and sequenced DNA and RNA, along an oxygen gradient-representing oxic, hypoxic, and anoxic conditions-in one of the world's largest dead zones located in the Baltic Sea. Cyanophages were detected at all stations and, based on partial genome contigs, had a higher alpha diversity and different beta diversity in the hypoxic-anoxic sediments, suggesting that cyanobacteria in dead zone sediments and/or environmental conditions select for specific cyanophages. Some of these cyanophages can infect cyanobacteria with potential consequences for gene expression related to their photosystem and phosphate regulation. Top cyanobacterial genera detected in the anoxic sediment included Dolichospermum/Anabaena, Synechococcus, and Cyanobium RNA transcripts classified to cyanobacteria were associated with numerous pathways, including anaerobic carbon metabolism and N2 fixation. Cyanobacterial blooms are known to fuel oxygen-depleted ecosystems with phosphorus (so-called internal loading), and our cyanophage data indicate the potential for viral lysis of cyanobacteria which might explain the high nutrient turnover in these environments.IMPORTANCE Cyanophages are viruses that target cyanobacteria and directly control their abundance via viral lysis. Cyanobacteria are known to cause large blooms in water bodies, substantially contributing to oxygen depletion in bottom waters resulting in areas called dead zones. Our knowledge of cyanophages in dead zones is very scarce, and so far, no studies have assembled partial cyanophage genomes and investigated their associated cyanobacteria in these dark and anoxic sediments. Here, we present the first study using DNA and RNA sequencing to investigate in situ diversity of cyanophages and cyanobacteria in dead zones. Our study shows that dead zone sediments contain different cyanophages compared to oxic sediments and suggest that these viruses are able to affect cyanobacterial photosystem and phosphate regulation. Furthermore, cyanophage-controlled lysis of cyanobacteria might also increase the turnover of carbon, phosphorus, and nitrogen in these oxygen-free environments at the bottom of the sea.", "doi": "10.1128/mSphere.00208-21", "pmid": "33910994", "labels": {"NGI Stockholm (Genomics Production)": null, "NGI Stockholm (Genomics Applications)": null, "National Genomics Infrastructure": null, "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pii", "key": "6/2/e00208-21"}, {"db": "pmc", "key": "PMC8092138"}], "notes": [], "created": "2021-06-09T12:16:56.678Z", "modified": "2024-01-16T13:48:39.964Z"}, {"entity": "publication", "iuid": "dfba8e4537274d90abb9a4c98eec18ae", "links": {"self": {"href": "https://publications.scilifelab.se/publication/dfba8e4537274d90abb9a4c98eec18ae.json"}, "display": {"href": "https://publications.scilifelab.se/publication/dfba8e4537274d90abb9a4c98eec18ae"}}, "title": "Meiofauna improve oxygenation and accelerate sulfide removal in the seasonally hypoxic seabed.", "authors": [{"family": "Bonaglia", "given": "Stefano", "initials": "S", "orcid": "0000-0003-4366-0677", "researcher": {"href": "https://publications.scilifelab.se/researcher/c02dd99f9fd14dd89d5c231260806720.json"}}, {"family": "Hedberg", "given": "Johanna", "initials": "J"}, {"family": "Marzocchi", "given": "Ugo", "initials": "U", "orcid": "0000-0002-4746-9944", "researcher": {"href": "https://publications.scilifelab.se/researcher/85d1ad4b2b3e48db9cc591f4574cb848.json"}}, {"family": "Iburg", "given": "Sven", "initials": "S"}, {"family": "Glud", "given": "Ronnie N", "initials": "RN", "orcid": "0000-0002-7069-893X", "researcher": {"href": "https://publications.scilifelab.se/researcher/c9598036867244f2a67d4041f179859c.json"}}, {"family": "Nascimento", "given": "Francisco J A", "initials": "FJA", "orcid": "0000-0003-3722-1360", "researcher": {"href": "https://publications.scilifelab.se/researcher/5c2cfb0d7a614432b9dfdfcfa3fc4644.json"}}], "type": "journal article", "published": "2020-07-00", "journal": {"title": "Mar Environ Res", "issn": "1879-0291", "volume": "159", "issue": null, "pages": "104968", "issn-l": null}, "abstract": "Oxygen depleted areas are widespread in the marine realm.

After 6 days, meiofauna increased the volume of oxidized, sulfide-free sediment by 68% and reduced sulfide fluxes from 8.8 to 0.4 mmol m-2 d-1. After 15 days, the difference with the control attenuated due to the presence of a cable bacteria population, which facilitated sulfides oxidation in all treatments. 16S rRNA gene analysis revealed that meiofauna affected microbial community structure (beta diversity).

Microbes are more efficient in degradation under aerobic than anaerobic conditions, but the majority of sediment by volume is generally anoxic. Incubation experiments were conducted to study the biodegradation potential of naphthalene-a common polycyclic aromatic hydrocarbon (PAH)-and the diversity of microbial communities in presence/absence of activated carbon (AC) under aerobic/anaerobic conditions. Radio-respirometry experiments with endogenous microorganisms indicated that degradation of naphthalene was strongly stimulated (96%) by the AC addition under anaerobic conditions. In aerobic conditions, however, AC had no effects on naphthalene biodegradation. Bioaugmentation tests with cultured microbial populations grown on naphthalene showed that AC further stimulated (92%) naphthalene degradation in anoxia. Analysis of the 16S rRNA gene sequences implied that sediment amendment with AC increased microbial community diversity and changed community structure. Moreover, the relative abundance of Geobacter, Thiobacillus, Sulfuricurvum, and methanogenic archaea increased sharply after amendment with AC under anaerobic conditions. These results may be explained by the fact that AC particles promoted direct interspecies electron transfer (DIET) between microorganisms involved in PAH degradation pathways. We suggest that important ecosystem functions mediated by microbes-such as hydrocarbon degradation-can be induced and that AC enrichment strategies can be exploited for facilitating bioremediation of anoxic oil-contaminated sediments and soils.", "doi": "10.1016/j.chemosphere.2020.126023", "pmid": "32007777", "labels": {"National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Applications)": "Service", "NGI Stockholm (Genomics Production)": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pii", "key": "S0045-6535(20)30216-2"}], "notes": [], "created": "2020-07-08T13:03:41.428Z", "modified": "2024-01-16T13:48:42.467Z"}, {"entity": "publication", "iuid": "6ef6a5481f8043e3a6bd28a7ef84d080", "links": {"self": {"href": "https://publications.scilifelab.se/publication/6ef6a5481f8043e3a6bd28a7ef84d080.json"}, "display": {"href": "https://publications.scilifelab.se/publication/6ef6a5481f8043e3a6bd28a7ef84d080"}}, "title": "Uncovering diversity and metabolic spectrum of animals in dead zone sediments.", "authors": [{"family": "Broman", "given": "Elias", "initials": "E", "orcid": "0000-0001-9005-5168", "researcher": {"href": "https://publications.scilifelab.se/researcher/63826da04a1f4f80bc3229df12bac9b7.json"}}, {"family": "Bonaglia", "given": "Stefano", "initials": "S", "orcid": "0000-0003-4366-0677", "researcher": {"href": "https://publications.scilifelab.se/researcher/c02dd99f9fd14dd89d5c231260806720.json"}}, {"family": "Holovachov", "given": "Oleksandr", "initials": "O", "orcid": "0000-0002-4285-0754", "researcher": {"href": "https://publications.scilifelab.se/researcher/7887fd76b35c47aaa67ac8ab7a1d07d5.json"}}, {"family": "Marzocchi", "given": "Ugo", "initials": "U", "orcid": "0000-0002-4746-9944", "researcher": {"href": "https://publications.scilifelab.se/researcher/85d1ad4b2b3e48db9cc591f4574cb848.json"}}, {"family": "Hall", "given": "Per O J", "initials": "POJ"}, {"family": "Nascimento", "given": "Francisco J A", "initials": "FJA", "orcid": "0000-0003-3722-1360", "researcher": {"href": "https://publications.scilifelab.se/researcher/5c2cfb0d7a614432b9dfdfcfa3fc4644.json"}}], "type": "journal article", "published": "2020-03-06", "journal": {"title": "Commun Biol", "issn": "2399-3642", "volume": "3", "issue": "1", "pages": "106", "issn-l": "2399-3642"}, "abstract": "Ocean deoxygenation driven by global warming and eutrophication is a primary concern for marine life. Resistant animals may be present in dead zone sediments, however there is lack of information on their diversity and metabolism. Here we combined geochemistry, microscopy, and RNA-seq for estimating taxonomy and functionality of micrometazoans along an oxygen gradient in the largest dead zone in the world. Nematodes are metabolically active at oxygen concentrations below 1.8 \u00b5mol L-1, and their diversity and community structure are different between low oxygen areas. This is likely due to toxic hydrogen sulfide and its potential to be oxidized by oxygen or nitrate. Zooplankton resting stages dominate the metazoan community, and these populations possibly use cytochrome c oxidase as an oxygen sensor to exit dormancy. Our study sheds light on mechanisms of animal adaptation to extreme environments. These biological resources can be essential for recolonization of dead zones when oxygen conditions improve.", "doi": "10.1038/s42003-020-0822-7", "pmid": "32144383", "labels": {"National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Applications)": "Service", "NGI Stockholm (Genomics Production)": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pii", "key": "10.1038/s42003-020-0822-7"}, {"db": "pmc", "key": "PMC7060179"}], "notes": [], "created": "2020-07-08T13:05:16.537Z", "modified": "2024-01-16T13:48:42.803Z"}]}
