	%X The objectives were to identify cyanide-degrading
bacteria and study cyanide removal efficiency. Agrobacterium
tumefaciens SUTS 1 was isolated. This is a new strain of
microorganisms for cyanide degradation. The maximum growth rate
of SUTS 1 obtained 4.7 × 108 CFU/ml within 4 days. The cyanide
removal efficiency was studied at 25, 50, and 150 mg/L cyanide. The
residual cyanide, ammonia, nitrate, nitrite, pH, and cell counts were
analyzed. At 25 and 50 mg/L cyanide, SUTS 1 obtained similar
removal efficiency approximately 87.50%. At 150 mg/L cyanide,
SUTS 1 enhanced the cyanide removal efficiency up to 97.90%. Cell
counts of SUTS 1 increased when the cyanide concentration was set
at lower. The ammonia increased when the removal efficiency
increased. The nitrate increased when the ammonia decreased but the
nitrite did not detect in all experiments. pH values also increased
when the cyanide concentrations were set at higher.
