PH Control Enables Simultaneous Enhancement of Nitrogen Retention and N₂O Reduction in Shewanella loihica Strain PV-4.

ABSTRACT: pH has been recognized as one of the key environmental parameters with significant impacts on the nitrogen cycle in the environment. In this study, the effects of pH on NO₃^-/NO₂^- fate and N₂O emission were examined with Shewanella loihica strain PV-4, an organism with complete denitrification and respiratory ammonification pathways. Strain PV-4 was incubated at varying pH with lactate as the electron donor and NO₃^-/NO₂^- and N₂O as the electron acceptors. When incubated with NO₃^- and N₂O at pH 6.0, transient accumulation of N₂O was observed and no significant NH₄⁺ production was observed. At pH 7.0 and 8.0, str
