N2 - A gram-negative, motile, fermentative, thermophilic bacterium, designated AR80T, was isolated from a high-temperature oil reservoir in Yabase Oilfield in Akita, Japan. Cells were rod-shaped, motile by means of polar flagella, and formed circular, convex, white colonies. The strain grew at 40-65 °C (optimum 60 °C), 0.5-9 % (w/v) NaCl (optimum 0.5-1 %), pH 6-9 (optimum pH 7.5), and elemental sulfur or thiosulfate serves as terminal electron acceptor. Phylogenetic analysis of 16S rRNA gene sequences indicated that strain AR80T belonged to the genus Petrotoga and shared approximately 94.5 % sequence similarity with the type species of this genus. The G + C content of genomic DNA was 32.4 mol% while the value of DNA-DNA hybridization between the closest relative species Petrotoga miotherma and AR80T was 58.1 %. The major cellular fatty acids of strain AR80 T consisted of 18:1 w9c, 16:0, and 16:1 w9c. Based on genetic and phenotypic properties, strain AR80T was different with other identified Petrotoga species and represents as a novel species, for which the name Petrotoga japonica sp. nov. is proposed. The type strain is AR80 T (=NBRC 108752T = KCTC 15103T = HUT 8122 T).
