Abstract:

As the Elizabethkingia sp.strain W8 isolated by our lab for the dominate bacteria of our further research,the degradation kinetics and biodegradation pathway were studied.The result shows that the optimal temperature,initial pH value and salt concentration for W8 is 35℃,pH 7.0 and 0.5% respectively.When the initial concentration of DBP was between 50 and 400mg/L,thestrain on the degradation of DBP is tested in line with the Gr.1 Monod kinetics model.The FT-IR analysis demonstrates that the degradation of DBP most likely follows the pathway: DBP→MBP→PA.
