%X Succinonitrile used as a sole source of carbon and nitrogen, two bacterium strains, named as J-1-3 and J-13-1, which had high degrading capacity for succinonitrile were isolated and screened out from acrylic fiber wastewater and biofilm in its treatment structure. Through morphological and biochemical method, the two strains were primarily identified as Pseudomonas spp. By tests in shaking flasks, it was determined that the strains can be optimum growth at 30 degrees C, with shaker rotary speed which indirectly reflected aeration capacity at 250 r/min, inoculum amount of 0.1%, and initial pH6. On the optimum conditions for growth, the degradation experiments on different initial concentrations of succinonitrile were carried out. The results indicate that the two strains, especially J-13-1 had high degrading efficiency for succinonitrile. With the initial concentration of succinonitrile at ca. 6000, 8000 and 10,000 mg/L, the degrading rates of succinonitrile by strain J-13-1 reached to 100% after 12.5 h, 14 h and 16 h, respectively.
