Isolation and Characterization of Pseudomonas sp. T-1 Degrading Terephthalic Acid

Terphthalic Acid를 분해한는 Pseudomonas sp. T-1의 분리 및 특성

26 bacterial strains capable of growing on Terephthalic acid (TPA) in minimal medium were isolated from soil and wastewater by selective enrichment culture, and among them, one isolate which was the best in the cell growth and TPA degradation was selected and identified as Pseudomonas sp. T-1 by its characteristics. Cell growth almost revealed a stationary phase at 24 hrs after cultivation. Cell growth dramatically increased in a minimal medium containing 0.1% of TPA as a sole carbon source and TPA was not detected any more at 80 hrs after cultivation. Therefore, it is suggested that Pseudomonas sp. T-1 could be effectively used for the biological treatment of wastewater containing TPA.
