Abstract

Degradation of phenanthrene by strains Pseudomonas putida BS3701 (pBS1141, pBS1142), Pseudomonas putida BS3745 (pBS216), and Burkholderia sp. BS3702 (pBS1143) was 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 (pBS143) 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).

摘要

在模型土壤系统中研究了恶臭假单胞菌BS3701（pBS1141，pBS1142）、恶臭假单胞菌BS3745（pBS216）和伯克霍尔德氏菌属BS3702（pBS1143）菌株对菲的降解情况。研究表明了所研究菌株之间菲中间体积累和摄取速率的差异，揭示了在模型系统中菌株BS3702（pBS143）降解菲过程中土壤中1-羟基-2-萘甲酸的积累情况。使用先前提出的用于评估萘降解效率的数学模型评估了菲的生物降解效率。预计联合使用恶臭假单胞菌BS3701（pBS1141，pBS1142）菌株和伯克霍尔德氏菌属BS3702（pBS1143）菌株可提高菲污染土壤中菲及其降解中间产物的降解效率。
