Impact of microbial Nocardia vaccinii IMB B-7405 surfactants on oil destruction in water

Abstract

The degree of oil degradation, as well as complex oil pollution with heavy metal in water in the presence of Nocardia vaccinii ІMV B-7405 biosurfactants was studied. The destruction of crude oil (2,6−6,0 g/l) in water) at 25−30 days after treatment with the post-fermentative culture liquid (5−10% v/v) containing biosurfactant was 76−94%.
