<i>Alteromonas nitratireducens</i> sp. nov., a Novel Nitrate-Reducing Bacterium Isolated from Marine Sediments, and the Evolution of Nitrate-Reducing Genes in the Genus <i>Alteromonas</i>.

ABSTRACT: Nitrate reduction serves as a pivotal process in the global nitrogen cycle, playing a crucial role in natural ecosystems and industrial applications. Although the genus Alteromonas is not traditionally regarded as a nitrate reducer, several Alteromonas strains have recently been found to be capable of doing so. However, the evolutionary trajectory of this capability remains undiscovered. In this study, 32 bacterial strains were isolated and cultivated from the tidal flat sediment in Hangzhou Bay and classified into the classes Cytophagia (n = 2), Alphaproteobacteria (n = 2), Gammaproteobacteria (n = 17), Flavobacteriia (n = 5), and Bacilli (n = 6). One nitrate-reducing strain, designated as CYL-A6^T, was identified by polyphasic ta
