A Gram-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated SK3863 T , was isolated from rotten biji (residue remaining after making tofu). This bacterium was characterized in order to determine its taxonomic position by using the polyphasic approach. Strain SK3863 T grew well at 25-37 °C on Reasoner’s 2A agar plates. On the basis of 16S rRNA gene sequence similarity, strain SK3863 T belonged to the family Comamonadaceae and was related to Ottowia beijingensis GCS-AN-3 T (96.5% sequence similarity) and Ottowia pentelensis RB3-7 T (96.4 %). Lower sequence similarities (96.2 %) were found to all of the other recognized members of the genus Ottowia. The G+C content of the genomic DNA was 65.8 mol%. The major respiratory lipoquinone was ubiquinone 8 and the major fatty acids were C 16: 1ω6c /C 16: 1ω7c , C 16: 0 and C 18: 1ω7c /C 18: 1ω6c . Strain SK3863 T could be differentiated genotypically and phenotypically from the recognized species of the genus Ottowia. The isolate therefore represents a novel species, for which the name Ottowia konkukae sp. nov. is proposed, with the type strain SK3863 T (=KCCM 43236 T =DSM 105395 T ).
