sp. nov., isolated from cow faeces.

A Gram-stain-negative, obligately anaerobic, non-motile, non-spore-forming, helical rod-shaped bacterium, designated AGMB01872, was isolated from faeces of a cow deposited in the National Institute of Animal Science (Wanju, Republic of Korea). Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain AGMB01872 was most closely related to DSM 3072 (= KCTC 25222, 96.6 %) which belonged to the family . Growth was occurred at 30-40 °C (optimum, 37 °C), pH 6-7 (optimum, pH 7) and in the presence of 0.5-1.0 % (w/v) NaCl. The genomic DNA G+C content of strain AGMB01872 was 35.9 mol%. The average nucleotide identity value between strain AGMB01872 and DSM 3072 was 72.1 %. Cells of strain AGMB01872 utilized d-glucose, maltose, d-xylose and l-arabinose. The major fatty acids (>10 %) were C (23.9 %), C (29.4 %), summed feature 5 (10.8 %) and summed feature 10 (30.3 %). The major end-product of glucose fermentation was succinate. Based on the phenotypic, phylogenetic, biochemical, genotypic and chemotaxonomic data, AGMB01872 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is AGMB01872 (= KCTC 25201=NBRC 115007=GDMCC 1.2573).
