Abstract

Proteobacterial methanotrophs—groups of microorganisms that utilize methane as a source of energy and carbon—have been known to utilize unique mechanisms to scavenge copper, namely, utilization of methanobactin, a polypeptide that binds copper with high affinity and specificity. Previously the possibility that copper sequestration by methanotrophs may lead to alteration of cuproenzyme-mediated reactions in denitrifiers and consequently increase emission of potent greenhouse gas N 2 O has been suggested in axenic and coculture experiments.
