Structure and function of high Arctic pelagic, particle-associated and benthic bacterial communities.

abstract：:Specialized organotrophic Bacteria 'syntrophs' and methanogenic Archaea 'methanogens' form a unique metabolic interaction to accomplish cooperative mineralization of organic compounds to CH4 and CO2 . Due to challenges in cultivation of syntrophs, mechanisms for how their organotrophic catabolism circumvents thermodyn...
