NEW MICROORGANISM, METHOD FOR RATING CORROSION RESISTANCE BASED ON CORROSION BY THE SAME, METHOD FOR JUDGING CORROSION BY THE SAME, AND METHOD FOR REDUCING CARBON DIOXIDE IN GAS USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a new microorganism having the ability to corrode iron or iron-containing alloy, to provide a method for rating the corrosion resistance of iron or an iron-containing alloy based on corrosion caused by the microorganism, to provide a method for judging the presence/absence of such corrosion based on the detection of the microorganism from corroded site(s), and to provide a method for reducing carbon dioxide in a gas utilizing the microorganism. PSOLUTION: The new microorganism is such as to be specified as Accession No. NITE ABP-252, belonging to Methanococcales order Methanococcaeae family. The method for rating corrosion resistance based on corrosion caused by the microorganism is also provided, being characterized in comprising the following procedure: The microorganism is brought into contact with iron or an iron-containing alloy and made to exist in water containing the iron or the alloy to effect corroding the iron or the alloy. The level of the resultant corrosion is then determined, thus rating the corrosion resistance of the iron or the alloy to the microorganism. PCOPYRIGHT: (C)2008,JPO&INPIT
