Phenols, widely used in Industries, are of growing concern owing to their high toxicity, carcinogenicity and wide distribution in Industrial wastes. In the present study, one Pseudomonas isolate, identified as Pseudomonas spp. was obtained using the enrichment process with 2,4,6- Trichlorophenol (2,4,6-TCP) as a sole carbon source. This isolate was found to be able to degrade phenol. The ability of Pseudomonas spp. isolate to remove phenol from a Industrial effluent was tested by a UV-VIS spectrophotometer. The results indicated that this isolate metabolized phenol in the meta-pathway. The optimal phenol degradation conditions of Pseudomonas spp. isolate were at pH 7.2 and 30oC. At the 160 mg/l of phenol concentration, the highest specific degradation rate was observed. Further increase in phenol concentration slowed down the degradation ability of the isolate. However, the supplementation of 1% glucose stimulated the growth of Pseudomonas spp. isolate and enhanced the ability to utilize phenol from the sample. Visible spectrophotometer results show that 70.70% of phenol in the effluent sample was metabolized after 50 days. In conclusion, pseudomonas spp. isolated in this study has ability of utilizing phenol compounds and demonstrates its potentials of degrading high concentration of phenol in Industrial effluents.
