Succinivibrio faecicola sp. nov., isolated from cow faeces

A Gram-stain-negative, obligately anaerobic, non-motile, non-spore-forming, helical rod-shaped bacterium, designated AGMB01872T, 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 AGMB01872T was most closely related to Succinivibrio dextrinosolvens DSM 3072T (= KCTC 25222T, 96.6 %) which belonged to the family Succinivibrionaceae . 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 AGMB01872T was 35.9 mol%. The average nucleotide identity value between strain AGMB01872T and S. dextrinosolvens DSM 3072T was 72.1 %. Cells of strain AGMB01872T utilized d-glucose, maltose, d-xylose and l-arabinose. The major fatty acids (>10 %) were C14 : 0 (23.9 %), C16 : 0 (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, AGMB01872T represents a novel species within the genus Succinivibrio , for which the name Succinivibrio feacicola sp. nov. is proposed. The type strain is AGMB01872T (= KCTC 25201T=NBRC 115007T=GDMCC 1.2573T).
