In marine anaerobic environments, methane is oxidized where sulfate-rich seawater meets
biogenic or thermogenic methane. In those niches, a few phylogenetically distinct microbial …

The oxidation of methane with sulfate is an important microbial metabolism in the global
carbon cycle. In marine methane seeps, this process is mediated by consortia of anaerobic …

To understand the biogeochemical roles of microorganisms in the environment, it is
important to determine when and under which conditions they are metabolically active …

Eukaryotic genomes are known to have garnered innovations from both archaeal and
bacterial domains but the sequence of events that led to the complex gene repertoire of …

Cold seep is a unique habitat for microorganisms in deep marine sediments, and microbial
communities and biogeochemical processes are still poorly understood, especially in …

Sulfate-coupled anaerobic oxidation of methane (AOM) is a major methane sink in marine
sediments. Multiple lineages of anaerobic methanotrophic archaea (ANME) often coexist in …

Tenericutes are a unique class of bacteria that lack a cell wall and are typically parasites or
commensals of eukaryotic hosts. Environmental 16S rDNA surveys have identified a number …

Abstract Archaeal anaerobic methanotrophs (“ANME”) and sulfate-reducing
Deltaproteobacteria (“SRB”) form symbiotic multicellular consortia capable of anaerobic …

Mangrove sediment is a crucial component in the global mercury (Hg) cycling and acts as a
hotspot for methylmercury (MeHg) production. Early evidence has documented the ubiquity …

Authigenic carbonates are one type of conspicuous manifestation in seep environments that
can provide long-term archives of past seepage activity and methane cycling in the oceans …
