Tetracyanonickelate (K2(Ni(CN)4), TCN) is one of the most toxic organics to living organisms. In this study, Klebsiella oxytoca (K. oxytoca) SYSU-011 (a cyanide- degrading bacterium), which was isolated from the wastewater of a metal-plating plant, was shown to be able to biodegrade TCN under anaerobic conditions. Two different media (Burk and NFG) were used to grow K. oxytoca. Results indicate that higher TCN biodegradation rate was observed when Burk medium was used as the growth media for K. oxytoca. In the nitrogen source addition experiment, TCN degradation was inhibited by the addition of nitrite. In the carbon source addition experiment, TCN degradation was enhanced by the addition of glucose and fructose. These findings would be helpful in designing a practical in situ or on-site treatment system inoculated with K. oxytoca for the treatment of TCN-containing wastewater.
