Bacteria capable of degrading 4-nonylphenol (NP) were isolated and identified, and their ability to degrade NP was determined. The screening of microorganisms in river water and soil led to a collection of 23 strains of bacteria and five strains of fungi. Two strains of bacteria, identified as <I>Pseudomonas</I> sp. and <I>Acidovorax</I> sp., possessed great ability for degrading NP. The NP degradation rate of <I>Pseudomonas</I> sp. did not change with the NP concentration (50-100mg/L) . In contrast, the NP degradation rate of <I>Acidovorax</I> sp. increased with increasing NP concentration. <I>Acidovorax</I> sp. possessed the greatest NP degradation activity at 35°C. No NP degradation activity was observed for <I>Pseudomonas</I> sp. at temperatures higher than 30°C. Even when non-NP carbon sources such as glucose or sucrose were added, the NP degradation rates for both bacteria did not decrease. In addition, the estrogenic activity of NP decreased depending on the amount of NP residues determined by the yeast two-hybrid system.
