| Outline of Final Research Achievements |
Microbiologically influenced corrosion (MIC) of metallic materials imposes a heavy economic burden. Eleven novel bacterial strains were isolated from brine of a natural gas recovery facility in Japan. Among eleven strains, strain NT050 oxidized the iron (Fe0) foil in the presence of nitrate and yeast extract. On the other hand, strain NT017 was related to nitrate-reducing and iron-oxidizing Prolixibacter denitrificans MIC1-1 based on the 16S rRNA gene sequence similarity, while did not oxidized Fe0 foil under any culture condition In this study, a novel iron-corroding bacterium was obtained by culture-depend technique. Furthermore, Prolixibacter contained both Fe0-corroding bacteria and Fe0-non-corroding bacteria.
