Bacteria-induced de-emulsification of water-in-oil petroleum emulsions

Biotechnology Letters Aims and scope Submit manuscript

Summary

The de-emulsifying ability of two bacteria (i.e.,N. amarae andC. petrophilum) has been demonstrated on water-in-oil petroleum field emulsions. De-emulsification by whole cultures and by washed cells was correlated with changes in the culture during growth. For each species, there was a particular growth phase which produced a species-dependent de-emulsification optimum.
