Abstract:
A gram-positive strain identified as Arthrobacter globiformis CECT 4500, tolerant to up to 1 M nitrate, was isolated from the grounds of a munitions factory. Under strict aerobic conditions, this bacterium used a wide variety of C-sources to obtain the energy required for growth, which took place when the nitrate concentration in the medium was below 150 mM. Cells of this bacterium growing in the absence of nitrate were seen as individual cells or forming pairs, whereas cells grown in the presence of nitrate formed short filaments. With ethylene glycol as the C-source, optimal conditions for the full nitrate removal by Arthrobacter were established under laboratory conditions with wastewaters from the synthesis of dinitroethylene glycol.
