Abstract: THIS SPECIFICATION DISCLOSES A PROCESS FOR THE GROWTH AND RECOVERY OF CELLS OF AN AEROBIC, HYDROCARBON-UTILIZING MICROORGANISM. THE CELLS OF THE MICROORGANISM ARE GROWN IN AN OXYGENATED CULTURE MEDIUM WHICH IS AN EMULSION OF A HYDROCARBON SUBSTRATE AND AN AQUEOUS MINERAL SALT NUTRIENT. THE CULTURE MEDIUM CONTAINS A NONIONIC SURFACTANT OF MAINTAIN THE EMULSION. THE PROCESS INVOLVES A PRELIMINARY STEP OF DETERMINING IN AN EMULSION SIMILAR TO THAT OF THE CULTURE MEDIUM THE PROPORTION OF THE SURFACTANT AT WHICH INVERSION OF THE EMULSION OCCURS. IN A SUBSEQUENT STEP, THE GROWTH OF THE MICROORGANISM IS CARRIED OUT EMPLOYING IN THE CULTURE MEDIUM A PROPORTION OF THE HYDROCARBON SUBSTRATE, AQUEOUS MINERAL SALT NUTRIENT AND THE SURFACTANT SUBSTANTIALLY EQUIVALENT TO THAT AT WHICH INVERSION IS ATTACHED. WITH THIS PROPORTION OF SURFACTANT IN THE CULTURE MEDIUM, THE MICROORGANISM GROWS AT AN OPTIMUN RATE AND THE CELLS THEREOF ARE READILY SEPARATED AND RECOVERED FROM THE CULTURE MEDIUM.

Abstract: THIS SPECIFICATION DISCLOSES INHIBITION OF FOAMING IN A LIQUID SYSTEM CONTAINING WATER AND A HYDROCARBON. INHIBITION IS EFFECTED BY THE PRESENCE IN THE SYSTEM OF PARTICLES OF A SOLID, INSOLUBLE MATERIAL. THESE PARTICLES HAVE A SURFACE AREA OF LESS THAN 50 SQUARE METERS PER GRAM AND A PORTION OF THEIR SURFACES IS OCCUPIED BY POLAR SITES. REPRESENTATIVE SOLID MATERIALS ARE POLY-2,6-DIMETHYL-1,4-PHENYLENE OXIDE, A COPOLYMER OF 2,6-DIMETHYL PHENOL AND 2METHYL-1,6-TETRADECYL PHENOL WHEREIN THE PROPORTION OF THE LATTER COMPOUND DOES NOT EXCEED ABOUT 20 PERCENT BY WEIGHT OF THE COPOLYMER, A COPOLYMER OF VINYL STEARATE AND MALEIC ANHYDRIDE, SUBLIMED SULFUR, SILICON CARBIDE, AND POLYTETRAFLUOROETHYLENE COMMINUTED UNDER CRYOGENIC CONDITIONS.
