Pseudomonas sp. CL7 from Sludge Removed 2,3,4,6-Tetrachlorophenol in Vivo and in Vitro Condition
The present research focused on 2,3,4,6-Tetrachlorophenol (2,3,4,6-TeCP) mineralizing bacterium from the sludge of pulp and paper industry and identified as Pseudomonas sp. CL7 by 16s rRNA gene sequences analysis. This isolate degraded 2,3,4,6-TeCP as indicated by stoichiometric release of chloride...

| Zusammenfassung: | The present research focused on 2,3,4,6-Tetrachlorophenol (2,3,4,6-TeCP) mineralizing bacterium from the sludge of pulp and paper industry and identified as Pseudomonas sp. CL7 by 16s rRNA gene sequences analysis. This isolate degraded 2,3,4,6-TeCP as indicated by stoichiometric release of chloride and biomass formation. High pressure liquid chromatography (HPLC) analysis showed that Pseudomonas sp. (CL7) was able to mineralize a higher concentration of 2,3,4,6-TeCP (600 mg/l or 2.5 mM) than any previously reported 2,3,4,6-TeCP degrading bacteria. As the concentration of 2,3,4,6-TeCP increased from 50 (0.21 mM) to 600 mg/l (2.5 mM), the reduction in the cell growth was observed and the 2,3,4,6-TeCP degradation was more than 85% in all the concentrations in the present study. CL7 was able to remove 100% of 2,3,4,6-TeCP from the sludge (in Vitro condition) when supplemented with 100 mg/l (0.42 mM) of 2,3,4,6-TeCP and grown for two weeks. This study showed that CL7 can be used for bioremediation of 2,3,4,6-TeCP |
