  abstract = {{W}ood falls are organic substrates sunken on the ocean floor that house a diversified fauna of marine invertebrates. {A}mong them, the echinoid {A}sterechinus elegans is found in various localities from the {W}est-{P}acific region and observations of its gut content indicate that it is a wood-feeding species. {T}he diversity of the microflora associated with its gut content was investigated by 16 r{RNA} gene cloning analysis and identified {P}roteobacteria, {P}lanctomycete, {F}irmicutes, {C}ytophaga-{F}lexibacter-{B}acteroides and {A}ctinobacteria. {C}lones 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. {F}urthermore, the analysis of the adenosine 5'-phosphosulphate ({APS}) reductase gene {P}ut in evidence the presence of several sulphide-oxidizing bacteria ({SOB}) belonging to the {A}lpha- and {G}amma-proteobacteria {W}hile some sulphate-reducing bacteria ({SRB}) affiliated to the {D}elta-proteobacteria were also detected. {APS} reductase clones were related to thioautotrophic symbionts of various marine invertebrates including tube worms and gutless oligochaetes. {T}hese results suggest that a part of the bacterial community associated with the gut content of {A}. elegans would be able to participate in the wood digestion and therefore to the echinoid nourishment. {F}urther analyses are however needed to clarify several aspects of this association.},
