Abstract
Methanotrophs play a critical role in the global carbon cycle, as well as in future strategies for mitigating climate change through their consumption of methane, a trace atmospheric gas much more potent than carbon dioxide in global warming potential. Copper uptake is critical for methanotrophic activity, and here, we show different approaches for copper uptake. This study expands our knowledge and understanding of how methanotrophs collect and compete for copper, and such information may be useful in future manipulation of methanotrophs for a variety of environmental and industrial applications.
