Influence of ZJUTB06-99’s concentration on the biodegradation. The effect of ZJUTB06-99’s concentration on the acrylonitrile’s biodegradation rate. The factor of ZJUTB06-99’s concentration showed the strongest influence on the response when it varied in the range of 20 to 100 mg/L. Especially, the degradation rate of acrylonitrile reached to 85.3% with the ZJUTB06-99’s concentration of 100 g/L. The results could be justified by the higher amounts of effective enzymes that were produced as the concentration of ZJUTB06-99 were increased
