Abstract

A novel Gram-stain-positive, motile, endospore-forming, rod-shaped bacterium, designated strain NEAU-3TGS17, was isolated from the head of an ant (). The isolate grew at 0–35 °C (optimum 28–30 °C), at pH 6.0–11.0 (optimum pH 7.0–8.0) and with 0–6 % (w/v) NaCl (optimum 0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-3TGS17 belonged to the genus Sequence similarities between strain NEAU-3TGS17 and members of the genus with validly published names DSM 11706, DSM 5, DSM 11713 and NBRC 110600) were 98.4–99.1 %. DNA–DNA relatedness values between strain NEAU-3TGS17 and its closest relatives were below 70 %. The major cellular fatty acids (>5 %) were iso-C, anteiso-C, C and iso-C. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The cell-wall peptidoglycan type was A4β with ornithine as the diamino acid and the predominant menaquinones were MK-8 and some MK-7. The DNA G+C content was 35.8 mol%. On the basis of phenotypic data and phylogenetic inference, strain NEAU-3TGS17 was classified as representing a novel species in the genus , for which the name sp. nov. is proposed. The type strain is NEAU-3TGS17 (=DSM 100484=CGMCC 1.15308).
