Bradyrhizobium ottawaense efficiently reduces nitrous oxide through high nosZ gene expression.

ABSTRACT: N₂O is an important greenhouse gas influencing global warming, and agricultural land is the predominant (anthropogenic) source of N₂O emissions. Here, we report the high N₂O-reducing activity of Bradyrhizobium ottawaense, suggesting the potential for efficiently mitigating N₂O emission from agricultural lands. Among the 15 B. ottawaense isolates examined, the N₂O-reducing activities of most (13) strains were approximately five-fold higher than that of Bradyrhizobium diazoefficiens USDA110^T under anaerobic conditions. This robust N₂O-reducing activity of B. ottawaense was confirmed by N₂O reductase (NosZ) protein levels and by mitigation of N₂O emitted by nodule decomposition in laboratory sys
