Compositional and Functional Shifts in the Epibiotic Bacterial Community of Shinkaia crosnieri Baba & Williams (a Squat Lobster from Hydrothermal Vents) during Methane-Fed Rearing.

ABSTRACT: The hydrothermal vent squat lobster Shinkaia crosnieri Baba & Williams harbors an epibiotic bacterial community, which is numerically and functionally dominated by methanotrophs affiliated with Methylococcaceae and thioautotrophs affiliated with Sulfurovum and Thiotrichaceae. In the present study, shifts in the phylogenetic composition and metabolic function of the epibiont community were investigated using S. crosnieri individuals, which were reared for one year in a tank fed with methane as the energy and carbon source. The results obtained indicated that indigenous predominant thioautotrophic populations, such as Sulfurovum and Thiotrichaceae members, became absent, possibly due to the lack of an energy source, and epibiotic communities were dominated by indigenous Methylococcaceae and
