Nitrate dissimilation under microaerophilic conditions by a magnetic spirillum.
During microaerophilic growth of magnetic spirillum MS-1 on tartrate and nitrate, a maximal cell density was obtained at an initial oxygen partial pressure of 17 Pa. A transient accumulation of nitrous oxide and a 1:2 (mol/mol) stoichiometry between tartrate oxidation and nitrate reduction were observed, indicating that the organism carried out a respiratory type of metabolism.
