Arctic lakes are a significant source of the greenhouse gas methane (CH(4) ), but the role that methane oxidizing bacteria (methanotrophs) play in limiting the overall CH(4) flux is poorly understood. Here, we used stable isotope probing (SIP) techniques to identify the metabolically active aerobic methanotrophs in upper sediments (0-1 cm) ...
