| Abstract: | Morphological and biochemical properties of the nitrogen-fixing strain Ochrobactrum intermedium ANKI, intensely growing on media with azo compounds, and its resistance to various common xenobiotics were investigated. The kinetics of azobenzene transformation by O. intermedium ANKI was studied. Under cometabolism conditions, up to 40 mg of azobenzene per liter of medium were decolorized within one week. It was shown that the strain possessed molybdenum-dependent nitrogenase activity, and its nitrogenase system was sensitive to oxygen and fixed nitrogen in the medium. |
