Abstract

A novel Gram-stain-negative and strictly anaerobic bacterial strain, designated KGMB02408 <superscript>T</superscript> , was isolated from faeces of a healthy human in the Republic of Korea. The isolate was characterized as non-motile, non-spore-forming and rod-shaped (variable in length). The results of phylogenetic analysis based on 16S rRNA gene sequences revealed that strain KGMB02408 <superscript>T</superscript> belonged to the genus Bacteroides and was most closely related to Bacteroides faecichinchillae JCM 17102 <superscript>T</superscript> (=KCTC 15666 <superscript>T</superscript> ; 96.5 %). Based on its whole-genome sequence, the DNA G+C content of the isolate was 39.5 mol%. The average nucleotide identity value between strain KGMB02408 <superscript>T</superscript> and related species, B. faecichinchillae JCM 17102 <superscript>T</superscript> , was 93.8 %. The major cellular fatty acids (>10 %) of the isolate were anteiso-C <subscript>15 : 0</subscript> , iso-C <subscript>17 : 0</subscript> -OH, summed feature 11 (iso-C <subscript>17 : 0</subscript> -OH and/or C <subscript>18 : 2</subscript> DMA) and C <subscript>16 : 0</subscript> . Menaquinone-8 (28.6 %) and menaquinone-10 (47.1 %) were detected as the major respiratory quinones in the isolate. The major end products of glucose fermentation produced by strain KGMB02408 <superscript>T</superscript> were lactic acid, acetic acid and formic acid. Based on its phylogenetic, phenotypic and chemotaxonomic characteristics, strain KGMB02408 <superscript>T</superscript> represents a novel species of the genus Bacteroides in the family Bacteroidaceae . The type strain is KGMB02408 <superscript>T</superscript> (=KCTC 15687 <superscript>T</superscript> =DSM 107828 <superscript>T</superscript> ).
