Abstract
Here, we report a genome sequence of Afipia carboxidovorans strain SH125 isolated from an anammox reactor. This facultative anaerobic strain possesses the clade I-type nitrous oxide (N(2)O) reductase gene, devoid of nitrite- and nitric oxide reductase genes. Deciphering the genome will help explore N(2)O reducers instrumental in N(2)O mitigation.
