Autores: Gaboyer, Frédéric.
Microbial communities inhabiting marine subsurface sediments were described up to 1922 mbsf (meters below the sea floor) andcould represent 0.6% of the total biomass. This microbial diversity, remaining elusive to cultivation, comprises groups specific to subsurface environments and groups of generalists found in contrasted habitats, all belonging to the 3 domains of life (Bacteria,Eukarya and Archaea). Although playing a major role in global geochemical cycles, the microbial ecology of the subseafloor remains largely unknown. The hostile conditions of subsurface sediments contrast with the descriptions of microbial activity andviability in the subseafloor. In this context, many questions related to the microbial physiology and the lifestyles of buried...
