| Abstract: | Degradation of phenanthrene by strains Pseudomona, Moscow, KMK, 2004simova, I.A. and Chernov, I.s putida BS3701 (pBS1141, pBS1142), Pseudomonas putida BS3745 (pBS216), and Burkholderia sp. BS3702 (pBS1143) were studied in model soil systems. The differences in accumulation and uptake rate of phenanthrene intermediates between the strains under study have been shown. Accumulation of 1-hydroxy-2-naphthoic acid in soil in the course of phenanthrene degradation by strain BS3702 (pBS1143) in a model system has been revealed. The efficiency of phenanthrene biodegradation was assessed using the mathematical model proposed previously for assessment of naphthalene degradation efficiency. The efficiency of degradation of both phenanthrene and the intermediate products of its degradation in phenanthrene-contaminated soil is expected to increase with the joint use of strains P. Putida BS3701 (pBS1141, pBS1142) and Burkholderia sp. BS3702 (pBS1143). |
