摘要: Nitrous oxide (N 2 O) is an important greenhouse gas and fundamental questions about the capacity of soil microbial communities to act not only as sources, but also as sinks for N 2 O remains unanswered. We evaluated the capacity of non-denitrifying N 2 O-reducers to mitigate the production of this greenhouse gas in soil. We showed experimentally that the addition of the non-denitrifying strain Dyadobacter fermentans, which possesses the previously unaccounted N 2 O reductase NosZII, to 11 different soils significantly reduced N …
