Nitrate dissimilation under microaerophilic conditions by a magnetic spirillum

Appl Environ Microbiol. 1980 Aug;40(2):429-30. doi: 10.1128/aem.40.2.429-430.1980.


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.
