Abstract
Due to unique genomic adaptations, Methanococcus maripaludis Mic1c10 exhibits severe corrosive behavior when in direct contact with Fe0. These adaptations are linked to attachment and effective growth on constructed surfaces. One such adaptation is that of a specific [NiFe]-hydrogenase that may anchor on the cell surface via glycosyl-glycosyl interactions to receive Fe0-electrons directly. Such an evolutionary response to constructed environments requires us to rethink methane cycling in human-altered ecosystems.
