Abstract

A novel, Gram-stain-positive, non-spore-forming, facultatively anaerobic bacterium, designated strain H21T32, was isolated from the faeces of an Oriental stork, . Cells formed cocci grouped in pairs, tetrads or conglomerates, and colonies on solid medium were pale yellow. Strain H21T32 belonged to the genus , family , order and class . The 16S rRNA gene sequences of the strain showed 97.06–97.34, 96.17–96.31 and 95.93–96.07 % similarity to the type strains of , and , respectively. The strain grew at 10–37 °C (optimum temperature: 30 °C), with 0–7 % (w/v) NaCl (optimum salinity: 0.5 %) and at pH 7–9 (optimum pH: 8). The main cellular fatty acids were C 9, C 9 and C. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. Respiratory quinones were not detected. Sugar components of the peptidoglycan were rhamnose, ribose and glucose. Amino acid components of the cell wall were -alanine, -glucose, -lysine, glycine and aspartic acid. The DNA G+C content of the strain was 37.1 mol%. Average nucleotide identity between strain H21T32 and CECT 9157 was 77.02 %, confirming that strain H21T32 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is H21T32 (=KCTC 33991=JCM 33222).
