Abstract

A novel strictly anaerobic bacterium, strain JBNU-10 T, was isolated from BALB/c mouse feces. Cells of the strain JBNU-10 T were Gram-stain positive, non-motile and rod-shaped. Optimum growth occurred at 37℃, with 1% (w/v) NaCl and at pH 7. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain JBNU-10 T belonged to the genus Adlercreutzia and were closely related to Adlercreutzia muris WCA-131-CoC-2 T (95.90%). The genome sequencing of strain JBNU-10 T revealed a genome size of 2,790,983 bp, a DNA G + C content of 69.4 mol%. It contains a total of 2,266 CDSs, 5 rRNA genes and 49 tRNA genes. According to the data obtained strain JBNU-10 T shared ANI value below 77.6- 67.7%, dDDH value below 23.8% with the closely type species. Strain JBNU-10 T possessed iso-C16:0 DMA, C18:1 CIS 9 FAME, and C18:0 DMA as the major fatty acids and had DMMK-6. The major end products of fermentation is propionate and acetate. Based on phylogenetic, physiological and chemotaxonomic characteristics, strain JBNU-10 T represent a novel species of the genus Adlercreutzia. The type strain is JBNU-10 T (= KCTC 25028 T = CCUG 75610 T).
