Sutterella faecalis sp. nov., isolated from human faeces

An obligately anaerobic, Gram-stain-negative, non-motile, non-spore-forming, and coccobacilli-shaped bacterial strain, designated KGMB03119 T , was isolated from human faeces from a Korean. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the isolate was a member of the genus Sutterella and most closely related to Sutterlla wadsworthensis KCTC 15691 T (96.8% 16S rRNA gene sequence similarity). The DNA G + C content of strain KGMB03119 T was 58.3 mol% as determined from its whole genome sequence. Strain KGMB03119 T was asaccharolytic, catalase-positive, oxidase- and urease-negative. Furthermore, the isolate was positive for alkaline phosphatase, leucine arylamidase, acid phosphatase, arginine arylamidase, alanine arylamidase, and glycine arylamidase. The major cellular fatty acids (> 10%) of the isolate were C 18:1 ω 9c and C 16:0 . Methylmenaquinone-5 (MMK-5, 100%) was the predominant isoprenoid quinone in the isolate. Based on the phylogenetic, physiological, and chemotaxonomic characteristics, strain KGMB03119 T represents a novel species, for which the name Sutterella faecalis sp. nov. is proposed. The type strain is KGMB03119 T (= KCTC 15823 T = NBRC 114254 T ).
