Outline of Final Research Achievements |
Prolixibacter denitrificans strain MIC1-1 from a crude-oil sample at an oil well is the first Fe0-corroding nitrate-reducing representative belonging to the order Bacteroidales. Thus, we characterized isolates from oil field and belonging to the phylum Bacteroidetes. Three strains MIC1-1, MIC1-4 and MIC3-8 isolated from crude-oil sample collected at an oil well in Tohoku region were a facultatively aerobic mesophilic chemoheterotrophic non-hydrogenotrophic bacteria. Strains MIC1-1 and MIC1-4 were Fe0-corroding nitrate-reducing bacteria. Strain MIC3-8 was a ferric-reducing bacterium. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MIC1-1 and MIC1-4 were a member of the genus Prolixibacter in the order Bacteroidales, and strain MIC3-8 was a member of the genus Draconibacterium in the order Bacteroidales. On the basis of a polyphasic taxonomic approach, novel species is proposed for strain MIC1-1, to be named Prolixibacter denitrificans.
