Diversity and function of epibiotic microbial communities on the galatheid crab, Shinkaia crosnieri. (39/69)

The galatheid crab, Shinkaia crosnieri (Decapoda: Galatheidae), forms dense colonies in the Iheya North and Hatoma Knoll deep-sea hydrothermal fields and has numerous setae covered with filamentous epibiotic microorganisms. Molecular phylogenetic analyses revealed that the epibiotic communities in S. crosnieri consisted mainly of yet-uncultivated phylotypes within Epsilonproteobacteria and Gammaproteobacteria in both hydrothermal vent fields. Uptake experiments using (13)C-labeled tracers clearly demonstrated that both H(13)CO(3)(-) and (13)CH(4) were assimilated into not only the epibiotic microbial communities associated with the setae, but also the epibiont-free tissue of living S. crosnieri. In addition, the incorporation of H(13)CO(3)(-) into the microbial cells was strongly stimulated by the presence of reduced sulfur compounds but not by H(2). In conclusion, the uptake experiments suggested that sulfur-oxidizing chemolithoautotrophic and methanotrophic production by the epibionts provides the nutrition for S. crosnieri.  (+info)
