Each of the six Prolixibacter strains was grown anaerobically at
25°C for 30 days under an atmosphere of
N2:CO2 (4:1) in a 50-ml serum bottle
containing 20 ml of ammonium-free YSw medium or the medium supplemented
with 10 mM nitrate and/or 2.8 mM ammonium. The concentrations of
nitrate, nitrite, and ammonium in each culture or in an aseptic control
at day 30 were determined, and those in the aseptic control were
subtracted from the respective values in each culture. Data represent
means and standard deviations (n = 3).
