| Abstract: | Twenty Strains were isolated from phosphorous sewage that can grow in medium containing potassium cyanate. Nine of them can remove cyanide at a rate of over 90%. In particular, strain AB200103 in can reduce CN- by 97. 1%. This strain can reduce 50 mg/L cyanide to 0. 5 mg/L after 72 h incubation. The treated water meets the criteria of state for discharged water. The optimum pH and temperature is 7. 7 and 29C respectively. |
