Resumo: | At continental margins, and more particularly in cold seep areas, microbial and animal communities were locally detected at the surface of the sediments. These communities grow using reduced chemical compounds (H2S, Methane, COZ ...) contained in the percolated cold fluids and produced by both geological and microbial processes. ln order to study microbial community diversity in these ecosystems and their role in the environment as well as to understand the environmental factors influencing the distribution and ecophysiology of these communities, surface (0-20 cmbsf) but also deeper (&lt;9 mbsf) sediments were collected at the Sonora Margin. Microbial communities have been studied using various molecular, cultural and microscopy approaches. This research allowed: i) to determine the structure and diversity of metabolically active microbial communities in sediments, ii) to highlight different ecophysiologies for methane cycling microorganisms (methanogens, ANME, SRB) and iii) to discover the presence of new microbial lineages and functions in the cold seeps sediments of the continental margins.
