Microbial reduction of N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO to dinitrogen (N\u003cjats:sub\u003e2\u003c/jats:sub\u003e) is the major consumption process but microbial N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO reduction under acidic conditions is considered negligible, albeit strongly acidic soils harbor \u003cjats:italic\u003enosZ\u003c/jats:italic\u003e genes encoding N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO reductase. Here, we study a co-culture derived from acidic tropical forest soil that reduces N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO at pH 4.5. The co-culture exhibits bimodal growth with a \u003cjats:italic\u003eSerratia\u003c/jats:italic\u003e sp. fermenting pyruvate followed by hydrogenotrophic N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO reduction by a \u003cjats:italic\u003eDesulfosporosinus\u003c/jats:italic\u003e sp. Integrated omics and physiological characterization revealed interspecies nutritional interactions, with the pyruvate fermenting \u003cjats:italic\u003eSerratia\u003c/jats:italic\u003e sp. supplying amino acids as essential growth factors to the N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO-reducing \u003cjats:italic\u003eDesulfosporosinus\u003c/jats:italic\u003e sp. Thus, we demonstrate growth-linked N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO reduction between pH 4.5 and 6, highlighting microbial N\u003cjats:sub\u003e2\u003c/jats:sub\u003eO reduction potential in acidic soils.\u003c/jats:p\u003e","long_citation_html":"He et al.
