| Abstract: | The possible use of a consortium of actinobacteria from the genus Rhodococcus immobilized on a polymeric carrier has been investigated for oilfield wastewater treatment in a bioreactor. It has been found that Rhodococcus opacus IEGM 263 and Rhodococcus ruber IEGM 231 cells remain viable at high concentrations of mineral salts in water and are able to oxidize oil hydrocarbons up to 62–81%. It has been shown that the consortium of rhodococci was more efficient in the elimination of hydrocarbons from wastewater than monocultures. |
