Corrosion Behavior of Microbes in the Crude Oil from South Siberian of Russia

The kinds of microbes separated from the crude oil of south Siberian of Russia were determined,Those microbes were cultivated and put into solutions.Some steel specimens were tested in the solution and in the crude oil under the same conditions for about 6 month.The corrosive behavior of microbes was compared and analyzed by observation of the corrosion characteristics on the surface of steel specimens.The steel specimens were markedly corroded in the solutions with microbes.
