Methanotrophic Activity in Relation to Methane Efflux and Total Heterotrophic Bacterial Production in a Stratified, Humic, Boreal Lake

Methanotrophic Activity in Relation to Methane Efflux and Total Heterotrophic Bacterial Production in a Stratified, Humic, Boreal Lake

We studied methanotrophic activity in the water column in relation to heterotrophic bacterial production and efflux of methane (CH4) from the lake surface in a small, stratified, humic, boreal lake (Valkea-Kotinen, southern Finland). During summer and winter stratification, the highest methanotrophi...

Zusammenfassung:We studied methanotrophic activity in the water column in relation to heterotrophic bacterial production and efflux of methane (CH4) from the lake surface in a small, stratified, humic, boreal lake (Valkea-Kotinen, southern Finland). During summer and winter stratification, the highest methanotrophic activities were in the metalimnion, where oxygen concentration was $
