Description
Summary:A possible adaptation of the association of Rhodococcus ruber and Rhodococcus opacus strains immobilized on modified sawdust to oil hydrocarbons in a column bioreactor was investigated. In the bioreactor, the bacterial population showed higher hydrocarbon and antibiotic resistance accompanied by the changes in cell surface properties (hydrophobicity, electrokinetic potential) and in the content of cellular lipids and biosurfactants. The possibility of using adapted Rhodococcus strains for the purification of oil-polluted water in the bioreactor was demonstrated.
