ABSTRACT:
There is provided a process for breaking or at least destabilizing oil-in-water emulsions and water-in-oil emulsions, which comprises adding to the emulsion a broth or portion of a broth resulting from the culture therein of specifically selected bacterial microorganisms of the genus Nocardia, Rhodococcus, Arthrobacter, Corynebacterium or Mycobacterium. In particular, the microorganisms, Nocardia amarae, Rhodococcus aurantiacus and Rhodococcus rubropertinctus have been found to yield broths, following cultivation, having exceptionally good properties as de-emulsifying agents.
