KINETICS OF THE BIODEGRADATION OF DIMETHYL PHTHALATE AND ANILINE BY SCENEDESMUS OBLIQNUS

Experimental results showed that Scenedesmus obliqnus has the ability of degradation to dimethyl phthalate(DMP) and aniline, the average biodegradation rates per day were found to be 12.0 and 42.6 mg/L under the initial DMP concentrations of 300 and 700mg/L and 2.4 and 4.3 mg/L under the initial aniline concentrations of 100 and 200 mg/L, respectively. Calculation of biodegradation kinetic equation newly suggested fits well with the observed values than Monod kinetic equation, and standard deviation between caloulated and observed values were 1.5 and 7.9mg/L under the initial DMP concentrations of 300 and 700 mg/L, and 1.3 and 1.1 mg/L under the initial aniline concentrations of 100 and 200 mg/L, respectively.
