Study on the Growth and Degradation Characteristics of Atrazine Degradation Strain J6

This paper mainly studies the growth and degradation characteristics of the Atrazine degradation strain J₆ which is isolated from the soil, collected from the corn field in northern China with a long history of atrazine application. The growth and the degradation characteristics at different pHs and temperatures are also studied. Adding J₆ into the medium by the ratio of 1 %(v/v), J₆ is able to degrade the atrazine completely in 84 h whose concentration in medium is 100 mg/L. When the medium was cultured at 30degC with a pH of 7, the growth and the degradation ability of J₆ become best.
