Abstract

Abstract Process for the immobilisation of one or more hydrocarbon - utilising microorganism on a plastic carrier in which the immobilisation is carried out in an aqueous nutrient medium to which a minor amount of a water-immiscible hydrocarbon substrate has been added. Further plastic carriers on which microorganisms have been immobilised and the use of the latter have been described.
