  • Compositions containing bioemulsifiers and a method for their preparation
    Patent number: 6512014
    Abstract: A bioemulsifier composition useful for forming and stabilizing oil-in-water emulsions, comprising an esterase protein of 32.5 KD, found in association with emulsan in the bacteria Acinetobacter. The esterase, or parts of it, are isolated from cell extracts of various strains of Acinetobacter, or produced by any other means. The bioemulsifier composition is further comprised of a water-soluble polysaccharide polymer of any source.

  • Cleaning of cargo compartments
    Patent number: 3941692
    Abstract: Oil is removed from sea water, for example, in the cleaning of tanks of oil transport ships, by utilizing bacteria or cell-free solutions from such bacteria in a confined space with the addition of a source of nitrogen and a source of phosphorus, under aerated conditions. The resultant microbial fermentation converts the oil to protein-containing by-products making it possible to discharge the contents of the tanks without oil contamination and, if desired, to recover useful by-products.
