Surfactants are amphipathic molecules which reduce stress at the interface, thereby increasing water solubility and availability of organic compounds are produced by bacteria, fungi, and yeasts. For the isolation of biosurfactant producing bacteria and lipases, was plant in inducing means 10% of sewage effluent from slaughterhouses and soils contaminated with hydrocarbons Province taps Trujillo - Peru. Isolates were seed in agar cultures lecithin and rhodamine agar for determination of lipase producers. The selected microorganisms were plate on blood agar and agar Siegmund and Wagner (SW) for preliminary selection of biosurfactants bacteria. Later it determined to those microorganisms producing surfactants by Emulsification Index (EI) and measurement of surface tension. Positive cultures these tests were select and identified by API galleries and molecular identification by DNA sequencin...
