Anaerosporobacter faecicola sp. nov. isolated from faeces of Korean cow

A novel bacterial isolate designated as strain AGMB01083T was isolated from Korean cow faeces deposited in the National Institute of Animal Science (Wanju, Republic of Korea). The bacterium is obligate anaerobic, Gram-strain-positive, and motile. Cells are straight or curved rod-shaped, flagella and spores are observed. Growth occurs between 20–40 °C (temperature optimum of 35 °C), at pH 7–9 (pH optimum of 7), and in the presence of 0.5–1.0 % (w/v) NaCl. Based on the 16S rRNA gene sequence analysis, the strain belongs to the genus Anaerosporobacter and is most closely related to A. mobilis HY-37-4T (=KCTC5027T, similarity, 95.7 %). The DNA G+C content is 36.2 mol%, determined by the whole-genome sequence. The average nucleotide identity value between strain AGMB01083T and strain A. mobilis HY-37-4T is 75.5 %, below the interspecies identity threshold value. The major cellular fatty acids (>10 %) of strain AGMB01083T are C16 : 0, C16 : 0 dimethyl acetal (DMA), and C16 : 0 3-OH. Based on the phylogenetic, phenotypic, biochemical, chemotaxonomic, and genomic characterization, strain AGMB01083T is proposed to be a novel species, named Anaerosporobacter faecicola, in the genus Anaerosporobacter . The type strain is AGMB01083T (=KCTC 15857T=NBRC 114517T).
