The results of present work showed that the oil destruction degree in water treated with surfactant preparation of Rhodococcus erythropolis IMV Ac-5017 have increased significantly in presence of 0.01 mM Cu2+ (55-70 %) compared to the samples without copper cations (30 %). It was determined that the addition of 0.050.1 mM of Cu2+ into the media with fried sunflower oil and glucose or with n- hexadecane led to increasing surfactant synthesis by strain IMV Ac-5017 by 40 % compared to the medium without metal. It was shown that the activity of alcanehydroxylase of IMV Ac-5017 strain increased by 1.5 and 2 fold in the presence of 0.05 and 0.1 mM Cu2+, respectively, in the reaction mixture.
