Документ Use of biosurfactant preparation of Rhodococcus erythropolis IMV Ac-5017 for remediation of water polluted with oil and heavy metals(2012) Filyuk, IrynaThe 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.Документ Water remediation by biosurfactant preparation of Rhodococcus erythropolis IMV Ac-5017 in presence of Cu2+(2012) Sofіlkanich (Morozova), Anna; Filyuk, Iryna; Pirog, TatianaIt was showed that the oil destruction degree have increased significantly in presence of Cu2+ and surfactant preparation of Rhodococcus erythropolisІМV Ac-5017 strain. The oil destruction intensification in presence of Cu2+ could be caused by Cu2+positive influence on alcanehydroxylase activity in ІМV Ac-5017 strain, as well as in indigenous microflora.
