摘要
Dissolved methane was investigated in the water column of eutrophic Lake Plu beta see and compared to temperature, oxygen, and sulfide profiles. Methane concentrations and delta-C-13 signatures indicated a zone of aerobic methane oxidation and additionally a zone of anaerobic methane oxidation in the anoxic water body. The latter coincided with a peak in hydrogen sulfide concentration. High cell numbers of aerobic and anaerobic methane-oxidizing microorganisms were detected by fluorescence in situ hybridization (FISH) or the more sensitive catalyst-amplified reporter deposition-FISH, respectively, in these layers.
