BIODEGRADATION OF NONYLPHENOL

摘要

Nonylphenol is the primary breakdown intermediate formed during biodegradation ofnonylphenol ethoxylates. Research indicates that nonylphenol has been found to be toxic toaquatic organisms and has been suspected of being xenoestrogenic. In addition to otherestrogenic effects, nonylphenol is suspected of contributing to the feminization of male fish insewage outflows. This paper focuses on determining biodegradation rates of nonylphenol.Conventional models such as the Monod and Haldane were applied to analuze respirometric dataobtained for nonylphenol biodegradation. Biodegradation experiments were conducted atdifferent nonylphenol concentrations. Results indicate that nonylphenol is biodegradable and thebiodegradation can be modeled using Haldane kinetics.
