| Abstract: | The interaction between the strains degrading polycyclic aromatic hydrocarbons, Pseudomonas putida BS3701 and Burkholderia sp. BS3702, was studied in the course of phenanthrene degradation in plant rhizosphere. Strain BS3702 was shown to accumulate 1-hydroxy-2-naphthoic acid (which is toxic for plants); it was then utilized by strain BS3701, which thereby increased the resistance of plants to the pollutant and to the toxic intermediate. With this type of interaction (cooperation), the efficiency of phenanthrene degradation was noted to decrease. |
