Organic matter lability modifies the vertical structure of methane-related microbial communities in lake sediments

Rissanen, Antti J.; Jilbert, Tom; Simojoki, Asko; Mangayil, Rahul; Aalto, Sanni L.; Khanongnuch, Ramita; Peura, Sari; Jäntti, Helena
Microbiology Spectrum (American Society for Microbiology, 2023)

Eutrophication increases the input of labile, algae-derived, organic matter (OM) into lake sediments. This potentially increases methane (CH4) emissions from sediment to water through increased methane production rates and ...
The influence of dissolved organic matter composition on microbial degradation and carbon dioxide production in pristine subarctic rivers

Saarela, Taija; Zhu, Xudan; Jäntti, Helena; Ohashi, Mizue; Ide, Jun'ichiro; Siljanen, Henri; Pesonen, Aake; Aaltonen, Heidi; Ojala, Anne; Nishimura, Hiroshi; Kekäläinen, Timo; Jänis, Janne; Berninger, Frank; Pumpanen, Jukka
Boreal environment research (Finnish Environment Institute, 2024)

Dissolved organic matter (DOM) degradation in freshwaters plays an important role in the global carbon cycle, yet there is limited understanding of how the origin and composition of DOM regulate the production of riverine ...
