Abstract
An obligately anaerobic, Gram-stain-positive, non-motile and coccoid- or oval-shaped bacterium, designated strain KGMB01111T, was isolated from faeces from a healthy Korean. Comparative analysis of 16S rRNA gene sequences indicated that KGMB01111T was closely related to Ruminococcus gauveauii CCRI-16110T (93.9 %) and Blautia stercoris GAM6-1T (93.7 %), followed by Clostridium nexile DSM 1787T (93.5 %), Blautia producta ATCC 27340T (93.4 %), Blautia hydrogenotrophica DSM 10507T (93.1 %) and Blautia coccoides ATCC 29236T (93.1 %) within the family Lachnospiraceae (Clostridium rRNA cluster XIVa). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that KGMB01111T formed a separate branch with species in the genus Blautia. The major cellular fatty acids (>10.0 %) were C16:0 and C18:1 cis 9 dimethyl acetal (DMA), and the major polar lipids were aminophospholipids and lipids. KGMB01111T contained meso-diaminopimelic acid in cell-wall peptidoglycan. The predominant end product of fermentation produced by KGMB01111T was acetic acid. Based on the whole-genome sequence, the DNA G+C content of the isolate was 44.7mol%. On the basis of the phenotypic, chemotaxonomic and phylogenetic characteristics, KGMB01111T represents a novel species within the genus Blautia for which the name Blautia faecicola sp. nov. is proposed. The type strain is KGMB01111T (=KCTC 15706T=DSM 107827T).
