Abstract

|
Pseudomonas putida 3SK, which was constructed by the conjugal transfer of the CAM::TOL^* plasmid of Pseudomonas putida CST3A and the NAH plasmid of Pseudomonas putida KCTC 2403 into n-alkane assimilating Pseudomonas putida KCTC 2405, showed a broad degradation spectrum and floc-forming ability. This strain degraded m-toluic acid, naphthalene, camphor and decane simultaneously. Hg^2+ at the concentration of 1 ppm in the minimal medium could not inhibit the growth of this strain. The degradation of m-toluic acid by Pseudomonas putida 3SK was not repressed by the easily utilizable compounds, such as glucose and succinate. But, the addition of formalin inhibited the growth of Pseudomonas putida 3SK. After the cultivation of this strain on the artificial wastewater containing m-toluic acid, naphthalene, camphor and decane for 24 hr, the initial COD value (1500) of the artificial wastewater was declined to 300.
