Abstract

A Gram-stain-positive and obligately anaerobic bacterial strain, BR72, forming ivory yellow colonies was isolated from a faecal sample of a healthy Korean woman. 16S rRNA gene sequence analysis indicated that strain BR72 belongs to cluster XIVa and represents a distinct phyletic line within the family . The most closely related strains were DSM 1787 (94.1 % 16S rRNA gene sequence similarity), ATCC 27758 (93.5 %), ATCC 27756 (93.5 %), ATCC 29176 (93.5 %), DSM 5434 (93.1 %) and DSM 3598 (92.9 %). The DNA G+C content of strain BR72 based on its genome sequence was 45.3 mol%. The major cellular fatty acids were C, C, and iso-C I and/or anteiso-C B. Acetic acid was produced from glucose fermentation. Other physiological and biochemical comparisons allowed the phenotypic differentiation of strain BR72 from the members of the family . Based on the phylogenetic and phenotypic findings, this strain is considered to represent a novel species of a new genus belonging to the family and the name gen. nov., sp. nov. is proposed. The type strain of is BR72 ( = KCTC 15479 = JCM 30749).
