Claims4
A method of inhibiting biocorrosion of a metal, comprising placing an agent comprising 1,9-nonanedial and/or 2-methyl-1,8-octanedial as an active ingredient in an environment where a microorganism causing the biocorrosion is present,
- wherein said biocorrosion is caused by at least one kind selected from the group consisting of a sulfate-reducing bacterium, a nitrate-reducing bacterium, a methane-producing bacterium, an iodide-oxidizing bacterium, an iron-oxidizing bacterium and a sulfur-oxidizing bacterium.
A method of inhibiting biocorrosion of a metal, comprising sterilizing a microorganism causing the biocorrosion with an agent comprising 1,9-nonanedial and/or 2-methyl-1,8-octanedial as an active ingredient,
- wherein said biocorrosion is caused by at least one kind selected from the group consisting of a sulfate-reducing bacterium, a nitrate-reducing bacterium, a methane-producing bacterium, an iodide-oxidizing bacterium, an iron-oxidizing bacterium and a sulfur-oxidizing bacterium.
