Microbiological contamination of turbine fuel in integral fuel tanks and fuel distribution systems has been a quality control problem since the late 1950’s. Many of these microorganisms found in aircraft fuel tanks and storage tanks utilize kerosene as a sole carbon and energy source and they often colonize at the interface of the fuel (upper) and water (lower) layers, forming a membranous pellicle. These interfacial pellicles adhere strongly to metal components and often produce corrosion and malfunctioning of these parts. The microbiological corrosion of aluminum alloys has been described by many investigators.1-3
