Methanotrophy in Extreme Environments
Abstract Methanotrophy is the ability of a few prokaryotes to grow on methane as a sole energy source. Aerobic methanotrophic bacteria are active in natural environments with pH values ranging from 1 to 11, temperatures ranging from 0 to 72°C and salinities up to 30%. In addition, anaerobic methanot...
