METHOD FOR PREVENTING CORROSION OF METAL

摘要

PROBLEM TO BE SOLVED: To provide a method capable of preventing corrosion of a steel material without requiring a power source or the like.SOLUTION: The method for preventing corrosion of metal by causing yeast (budding yeast) to stick onto the surface of a steel material to increase the potential on the surface thereof to suppress the reduction of oxygen or the like on the surface thereof, comprises causing bacterial flora 102 including yeast to stick onto the surface of a steel material 101. Yeast is stuck onto the surface of the steel material together with water. Yeast may be at least one selected from MT8-1 and BY4741. Such yeast proliferates by itself in the natural environment.
