Use of biosurfactant preparation of Rhodococcus Erythropolis IMV AC-5017 forremediation of water polluted with oil and heavy metals

摘要

The results of present work showed that the oil destruction degree inwater treated with surfactant preparation of Rhodococcus erythropolis ?МV Ac-5017have increased significantly in presence of 0.01 mM Cu2+ (55–70 %) compared to thesamples without copper cations (30 %). It was determined that the addition of 0.05–0.1 mM of Cu2+ into the media with fried sunflower oil and glucose or with nhexadecaneled to increasing surfactant synthesis by strain ?МV Ac-5017 by 40 %compared to the medium without metal. It was shown that the activity ofalcanehydroxylase of ?МV Ac-5017 strain increased by 1.5 and 2 fold in the presenceof 0.05 and 0.1 mM Cu2+, respectively, in the reaction mixture.
