Bacillus subtilis grown on glucose produced a de-emulsifier that broke down model oil-in-water emulsions. The deemulsification increased with contact time and the recovery of oil was 98% with 0.6 mg de-emulsifier/ml emulsion. GLC and i.r. analysis of the molecule extracted from cell-free broth demon

โฆ Synopsis
Nocardia c~arae has been shown to be a potent biological de-emulsifier of model oil-in-water emulsions and petroleum water-in-oil field emulsions. N. amarae is reported here to de-emulsify petroleum oil-in-water field emulsions. Parameters affecting the growth and the de-emulsifying ability of this bacterium have been examined. Bacteria-induced de-emulsifying activity could be useful in clarifying tailings ponds and sludges.

The stability of water-in-Guanipa crude emulsion was studied as a function of pH and the electrolyte concentration of mono-and polyvalent metal chlorides in the initial aqueous phase. The natural crude showed a medium to strong i.r. absorbance from silicon groups indicating that emulsion stability i
