| variations in archaeal and bacterial diversity associated with the sulfate-methane transition zone in continental margin sediments (santa barbara basin, california). | the sulfate-methane transition zone (smtz) is a widespread feature of continental margins, representing a diffusion-controlled interface where there is enhanced microbial activity. smtz microbial activity is commonly associated with the anaerobic oxidation of methane (aom), which is carried out by syntrophic associations between sulfate-reducing bacteria and methane-oxidizing archaea. while our understanding of the microorganisms catalyzing aom has advanced, the diversity and ecological role of ... | 2009 | 19139232 |
