Sediments with their natural nematofauna communities from Bizerte lagoon (Tunisia) were subjected to a PAH mixture (100&nbsp;ppm) of phenanthrene, fluoranthene, and pyrene during 30&nbsp;days. Nematode abundance and diversity significantly decreased, and the taxonomic structure was altered. Results from multivariate analyses of the species abundance data revealed that PAH treatments were significantly different from the control. <em class=\"EmphasisTypeItalic \">Spirinia parasitifera</em> became the dominant species (70&nbsp;% relative abundance) and appeared to be an “opportunistic” species to PAH contamination while <em class=\"EmphasisTypeItalic \">Oncholaimus campylocercoides</em> and <em class=\"EmphasisTypeItalic \">Neochromadora peocilosoma</em> were strongly inhibited. Biostimulation (addition of mineral salt medium) and bioaugmentation (inoculation of a hydrocarbonoclastic bacterium) were used as bioremediation techniques. Bioremediation treatments enhanced degradation of all three PAHs, with up to 96&nbsp;% degradation for phenanthrene resulting in a significant stimulation of nematode abundance relative to control microcosms. Nevertheless, these treatments, especially the biostimulation provoked a weak impact on the community structure and diversity index relative to the control microcosms suggesting their feasibility in biorestoration of contaminated sediments.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Responses of a free-living benthic marine nematode community to bioremediation of a PAH mixture","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:49.738056","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sediment; Polycyclic aromatic hydrocarbons; Free-living nematodes; Community response; Biostimulation; Bioaugmentation ","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2019-07-17","DateCreate":"2019-07-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000363966900010","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s11356-014-3343-4"},"refs":null,"anarec":{"AnaID":312832,"PubliDate":2015,"Pagination":"15307-15318","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":"20","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45312,"SerRR":"Environmental Science and Pollution Research.
