Aerobic methane-oxidizing bacteria (MOB) are a highly
specialized and important group of ubiquitous bacteria that
are capable of utilizing methane as the sole source of carbon
and energy and, therefore, represent the largest global
methane sink. They inhabit environments where both
methane and oxygen are present, such as soils, wetlands,
freshwater and marine systems, lakes and sediments
(Bowman, 2006).
