Abstract

|
A strictly anaerobic bacterium, designated as strain KGMB-03357T, was isolated from the faeces of a healthy Korean selected by Bundang Seoul National University based on health status. Cells of strain KGMB03357T are Gram-stain-positive, non-motile, non-spore-forming, and observed as straight or curved rods. The isolate grew at 10?45°C (optimum temperature of 40°C) and a pH range of 5.1?10.5 (optimum pH of 6.8). Analysis of phylogenetic trees based on the 16S rRNA gene sequences revealed that strain KGMB03357T forms a lineage within the genus Anaerotignum, and is most closely related to Anaerotignum lactatifermentans G17T (= KCTC 15066T, 96.1%), Anaerotignum propionicum DSM 1682T (= KCTC 5582T, 94.9%), Anaerotignum neopropionicum DSM 03847T (= KCTC 15564T, 94.9%), and Anaerotignum aminivorans SH021T (= KCTC 15705T, 94.8%). The ANI values between strain KGMB 03357T and members of the genus Anaerotignum were 73.3?71.0%, which are below the ANI criterion for interspecies identity. The DNA G + C content based on the whole-genome sequence is 47.3 mol%. The major cellular fatty acids of strain KGMB03357T are C16:0, C18:0, C18?1 cis 9, and anteiso-C15?0. Strain KGMB03357T contains meso-diaminopimelic acid as the diagnostic amino acid in the cell wall peptidoglycan. Based on the phenotypic, phylogenetic, and genomic properties, strain KGMB 03357T represents a novel species of the genus Anaerotignum, for which the name Anaerotignum faecicola sp. nov. is proposed. The type strain is KGMB03357T (= KCTC 15736T = DSM 107953T).
