Degradation of methyl parathion by Pseudomonas putida

N L Rani, D Lalithakumari
Canadian Journal of Microbiology 1994, 40 (12): 1000-6
Pseudomonas putida utilized methyl parathion as sole carbon and (or) phosphorus source. The bacterium elaborated the enzyme organophosphorus acid anhydrase, which hydrolyzed methyl parathion to p-nitrophenol. p-Nitrophenol was further degraded to hydroquinone and 1,2,4-benzenetriol. The final ring compound, 1,2,4-benzenetriol, was cleaved by benzenetriol oxygenase to maleyl acetate.
