Gammaproteobacterial methanotrophs dominate methanotrophy in aerobic and anaerobic layers of boreal lake waters
Rissanen, Antti J.; Saarenheimo, Jatta; Tiirola, Marja Annika; Peura, Sari; Aalto, Sanni L; Karvinen, Anu; Nykänen, Hannu (2018)
articleSmall oxygen-stratified humic lakes of the boreal zone are important sources of methane to the atmosphere. Although stable isotope profiling has indicated that a substantial part of methane is already oxidized in the ... -
Microbial community response on wastewater discharge in boreal lake sediments
Saarenheimo, Jatta; Aalto, Sanni L; Rissanen, Antti J.; Tiirola, Marja (2017)
articleDespite high performance, municipal wastewater treatment plants (WWTPs) still discharge significant amounts of organic material and nitrogen and even microbes into the receiving water bodies, altering physico-chemical ... -
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 (10 / 2023)
articleEutrophication 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 ... -
Sediment diffusion method improves wastewater nitrogen removal in the receiving lake sediments
Aalto, Sanni L; Saarenheimo, Jatta; Ropponen, J; Juntunen, J; Rissanen, Antti J.; Tiirola, Marja (2018)
articleSediment microbes have a great potential to transform reactive N to harmless N2, thus decreasing wastewater nitrogen load into aquatic ecosystems. Here, we examined if spatial allocation of the wastewater discharge by a ... -
Vertical stratification patterns of methanotrophs and their genetic controllers in water columns of oxygen-stratified boreal lakes
Rissanen, Antti J; Saarela, Taija; Jäntti, Helena; Buck, Moritz; Peura, Sari; Aalto, Sanni L; Ojala, Anne; Pumpanen, Jukka; Tiirola, Marja; Elvert, Marcus; Nykänen, Hannu (2021)
articleThe vertical structuring of methanotrophic communities and its genetic controllers remain understudied in the water columns of oxygen-stratified lakes. Therefore, we used 16S rRNA gene sequencing to study the vertical ...
