Ammonium Production by Dissimilatory Nitrate Reducers Isolated from Baltic Sea Water as Indicated by 15N Study

摘要

Bacteria able to perform dissimilatory nitrate reduction to ammonium were isolated from low-oxygen masses in the Baltic Sea. In liquid media enriched with ¹⁵NO3⁻ and incubated anaerobically, the NH4⁺-producing isolates transformed 25 to 72% of the ¹⁵NO3⁻ to ¹⁵NH4⁺.
