The ability of a lipase and surfactant in combined form in solution to remove fatty soil was investigated. The specific conductivities, binding isotherms, surface tensions, solubilization of Yellow OB were measured using Chromobacterium vicosum (Chr) and sodium dodecyl sulfate (SDS) as the lipase and surfactant, respectively. The removal of squalane soil by this means was also examined. <BR>SDS interacts with the protein of Chr to afford a Chr-SDS complex (cluster). The surface tension of the combined lipase-surfactant solution reaches a plateau at a lower concentration than when SDS is present alone. As the concentration of SDS increases, oily materials solubilize in the hydrophobic region as a result of interaction between the cluster and free surfactant. The data of the present study indicate solubilization to be quite important for the removal of fatty soil in a Chr-SDS combined system.
