Among them, the echinoid <i>Asterechinus elegans</i> is found in various localities from the West-Pacific region and observations of its gut content indicate that it is a wood-feeding species. The diversity of the microflora associated with its gut content was investigated by 16 rRNA gene cloning analysis and identified <i>Proteobacteria, Planctomycete, Firmicutes, Cytophaga-Flexibacter-Bacteroides</i> and <i>Actinobacteria</i>. Clones were related to bacteria from the gut of phytophageous (including wood-feeding) animals but also from sulphide-rich environments such as whale carcasses, mangrove soils and marine sediments of notably hydrothermal vents and cold seeps. Furthermore, the analysis of the adenosine 5'-phosphosulphate (APS) reductase gene Put in evidence the presence of several sulphide-oxidizing bacteria (SOB) belonging to the Alpha- and Gamma-proteobacteria While some sulphate-reducing bacteria (SRB) affiliated to the Delta-proteobacteria were also detected. APS reductase clones were related to thioautotrophic symbionts of various marine invertebrates including tube worms and gutless oligochaetes. These results suggest that a part of the bacterial community associated with the gut content of <i>A. elegans</i> would be able to participate in the wood digestion and therefore to the echinoid nourishment. Further analyses are however needed to clarify several aspects of this association.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"First insights into the gut microflora associated with an echinoid from wood falls environments","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":"Wood falls; Echinoids; Gut bacteria; 16S rRNA gene analysis;","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2013-06-17","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000273205200006","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":210712,"PubliDate":2009,"Pagination":"343-352","XtraPublOfAnaID":null,"ISBN":null,"Volume":"50","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42348,"SerRR":"Cahiers de Biologie Marine.
