Abstract: | bacterial consortium has been isolated containing Pseudomonas spp. strains S1 and S2, which was able to degrade p‐nitrophenol (PNP). The strains were isolated from agricultural soil contaminated with organophosphorus pesticides. Pseudomonas spp. strain S2 could convert p‐nitrophenol to 4‐nitrocatechol (4NC) after pre‐exposure to phenol, when PNP was used as the only carbon source in the medium. Pseudomonas spp. strain S2, when mixed with strain S1 in the ratio 1:5 respectively, decolorised PNP completely. |
