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 an Fe0 foil immersed in 20 ml of
corrosion-test medium or the medium containing 10 mM sulfate in place of
nitrate. The concentrations of oxidized iron, nitrate, nitrite, and
ammonium in each culture 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).
–: Not determined.
