Characterization of Picric Acid Degradation by Rhodococcus sp. PN1.

Mechanism of 4-Nitrophenol Oxidation in Rhodococcus sp. Strain PN1: Characterization of the Two-Component 4-Nitrophenol Hydroxylase and Regulation of Its Expression

“…This bacterium can degrade not only mono-NPs, including 4-NP, but also poly-NPs, such as 2,4-dinitrophenol and 2,4,6-trinitrophenol (picric acid) (1). Analyses of the metabolites in NP degradation revealed that PN1 degrades 4-NP through the 4-NC pathway, whereas it also degrades 2,4-dinitrophenol and picric acid via the corresponding hydride-Meisenheimer complexes (1,13,44). Thus, PN1 has at least two quite different pathways for NP degradation.…”
