Molecular diversity of methanotrophs in Transbaikal soda lake sediments and identification of potentially active populations by stable isotope probing.


Soda lakes are an environment with an unusually high pH and often high salinity. To identify the active methanotrophs in the Soda lake sediments, sediment slurries were incubated with a 10% (v/v) (13)CH(4) headspace and the (13)C-labelled DNA was subsequently extracted from these sediments following CsCl density gradient centrifugation. This DNA was then… (More)
