Alejandra's paper on "Analysing seasonal variations of methane oxidation processes coupled with denitrification in a stratified lake using stable isotopes and numerical modeling" got accepted in Geochimica et Cosmochimica Acta, a leading peer-reviewed journal in biogeochemistry.
In the 1970s, methane oxidation in anaerobic environments was observed to be linked to bacterial sulfate reduction and has become a history of inquiry into the biological phenomena responsible for anaerobic methane oxidation. Later, it was demonstrated under laboratory conditions that methane can also be oxidized with nitrate as electron acceptor. In our first study performed at Ostersee, located close to Munich, we have demonstrated that anaerobic oxidation of methane (AOM) is linked with nitrate and additionally coupled to anammox (Einsiedl et al. 2020, Biogeosciences). In the new study published by Alejandra we could clearly show that the process of AOM with nitrate is important over nearly a full year within the lake by separating aerobic and anaerobic methane oxidation by numerical modeling.
Thanks to everyone involved in this interesting and outstanding study that provide important information on the C and N cycles of lakes.
