%X One strain of imazethapyr degradable bacteria was isolated from the mixture of imazethapyr production factory's sludge and the soil that was contaminated with imazethapyr for a long time. The strain could degrade imazethapyr more than 90% within 72 h when it grew in 500 mg/L imazethapyr condition. When pH was 5, the bacteria could degrade all the imazethapyr of 500 mg/L in 72 h, but when pH was 8 and 9, only 50% imazethapyr was degraded which showed acid condition was more compatible than that of alkalescency for this bacteria growing. The higher degradation ratio at 25 degrees C and 30 degrees C was observed and the optimum condition for the bacteria to degrade imazethapyr was pH = 5 and 25 degrees C. Characterizing by physiological and biochemical properties as well as 16S rRNA sequence analysis, the strain is related and shared characteristics of the genus Alcaligenes sp.
