Surfactant Enhanced Bioremediation of Saline Diesel Contaminated Water by a Novel Bacterial Halophilic Consortium

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The use of microorganisms is an evolving method for the degradation of hydrocarbon contaminants. In this aim, halophilic hydrocarbon degrading bacteria were isolated from oil contaminated soil in Tunisia. A lipopeptide biosurfactant produced by Bacillus subtilis SPB1 was tested to increase diesel biodegradation along with co‐inoculation with ...

Micellar and Solubilization Properties of Biological Surfactant Surfactin

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.
