ABSTRACT The Okinawa Trough (OT) is a back-arc basin with a wide distribution of active
cold seep systems. However, our understanding of the metabolic function of microbial …

Shallow methane/sulfate transition zones in cold seeps are hotspots to study microbially
mediated geochemical cycles due to high methane fluxes. However, our knowledge about …

Deep-sea hydrothermal vents have been extensively explored around the globe in the past
decades, and the diversity of microbial communities and their ecological functions related to …

In deep-sea cold seeps, microbial communities are shaped by geochemical components in
seepage solutions. In the present study, we report the composition of microbial communities …

A combination of physicochemical and radiotracer analysis, high-throughput sequencing of
the 16S rRNA, and particulate methane monooxygenase subunit A (pmoA) genes was used …

Environmental heterogeneity in cold seeps is usually reflected by different faunal
aggregates. The sediment microbiome, especially the geochemical cycling-associated …

Cold seeps create diverse habitats in the deep sea and play an important role in the global
carbon cycling. Anaerobic oxidation of methane (AOM) and biogenic mineralization are …

Due to their extreme water depths and unique physicochemical conditions, deep-sea
ecosystems develop uncommon microbial communities, which play a vital role in …

Cold seep ecosystems are developed from methane-rich fluids in organic rich continental
slopes, which are the source of various dense microbial and faunal populations. Extensive …

Summary Diversity of Bacteria and Archaea was studied in deep marine sediments by PCR
amplification and sequence analysis of 16S rRNA and methyl co‐enzyme M reductase …
