METHANOTROPHIC ABILITY OF MOSSES AND LICHENS ASSOCIATED BACTERIA IN PERMAFROST ECOSYSTEMS OF EASTERN SIBERIA
Methanotrophic bacteria are unique group of microorganisms structurally and functionally adapted to use methane as a source of carbon, which is of great interest due to their ability to oxidize atmospheric methane. Methanotrophs are known to associate with mosses, which provide bacteria by habitat a...
