Abstract

A bacterial strain designated BG109 was isolated from bamboo grove soil, and subjected to polyphasic taxonomic characterization. BG109 is an aerobic, non-motile, Gram-stain-positive and endospore-forming bacterium. BG109 showed growth at 10–40 °C (optimum, 37 °C), at pH 4–10 (optimum, 8), and in the presence of 0–7 % NaCl concentration (optimum, 0–1 %). The predominant menaquinone of BG109 was MK-7, and the cell wall peptidoglycan contained major amounts of –diaminopimelic acid as the diagnostic diamino acid. The diagnostic polar lipids were diphosphatidylglycerol and phosphatidylglycerol, and unidentified phospholipids and glycolipids were also present. The major fatty acids were anteiso-C, iso-C, iso-C, iso-C and C. The chemotaxonomic properties of BG109 were generally consistent with those of members of the genus . BG109 shared highest 16S rRNA gene sequence similarities with ‘’ KUDC1714 (99.26 %), DSL-17 (98.17 %), SW-211 (98.16 %) and JSM 100118 (97.13 %), all of which were well below the suggested cutoff level for species distinction. The genome level relatedness also confirmed the separation of BG109 from other species of the genus . Thus, it is evident that BG109 merits recognition as representing a novel species of the genus , for which the name sp. nov. is proposed. The type strain is BG109 (=KCTC 43190=JCM 34515).
