PROBLEM TO BE SOLVED: To provide a method for simply recovering a microorganism existing in the corroded portion of a metal corroded in an environment contacting with a liquid containing a liquid fuel or an oil. SOLUTION: This method for recovering the microorganism related to the corrosion of the metal comprises adding and suspending at least one of a liquid, attachments, rusts, and sludge existing in the corroded portion of a metal, separating the phase to recover the water phase, adjusting the recovered water to pH 7 to 10 to precipitate a metal ion existing in the recovered water, filtering the supernatant with a membrane having a pore diameter of≤0.5μm to recover the microorganism related to the corrosion of the metal on a filtration membrane.
