Kelthane degradation by genetically engineered Pseudomonas aeruginosa BS827 in a soil ecosystem.

Abstract

The aim of this study was to study the degradation of kelthane by Pseudomonas aeruginosa BS827, which carried the plasmid pBS3. This plasmid encodes naphthalene oxidation. The strain was able to survive in the presence of kelthane and to retain its degradative ability. Kelthane also stabilized the biodegradative plasmid that was preserved by 70 to 100% of the cell population. Cells deficient in Nah or Sal characters were less effective in degrading kelthane, whereas plasmid-free cells lost this ability completely. Evidently, the degradative activity of P. aeruginosa BS827 was conditioned by plasmid determinants coupled with genes of the plasmid pBS3 Nah region
