Simultaneous uptake of ammonium and nitrate salts by an aerobic culture of Bacillus licheniformis No. 40-2.
A one-step elimination of NO3- and NH4+ through aerobic culture of Bacillus licheniformis is proposed. The cell growth markedly increased in a medium containing 1.5 mM of FeSO4 under aerobic conditions. At the stationary phase of cell growth, the NO3- and NH4+ disappeared entirely from the medium. This bacterial culture could be applied to bioremediation systems.
