Abstract:
Degraded peatlands are often rewetted to prevent oxidation of the peat, which reduces CO 2 emission. However, the created anoxic conditions will boost methane (CH 4 ) production and thus emission. Here, we show that submerged Sphagnum peat mosses in rewetted-submerged peatlands can reduce CH 4 emission from peatlands with 93%. We were able to mimic the field situation in the laboratory by using a novel mesocosm set-up. By combining these with 16S rRNA gene amplicon sequencing and qPCR analysis of the pmoA and mmoX genes, we showed that submerged Sphagnum mosses act as a niche for CH 4 oxidizing bacteria. The tight association between Sphagnum peat mosses and methane oxidizing bacteria (MOB) significantly reduces CH 4 emissions by peatlands and can be studied in more detail in the mesocosm setup developed in this study.
