摘要
A bacterial strain designated BG109T was isolated from bamboo grove soil, and subjected to polyphasic taxonomic characterization. BG109T is an aerobic, non-motile, Gram-stain-positive and endospore-forming bacterium. BG109T 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 BG109T was MK-7, and the cell wall peptidoglycan contained major amounts of meso-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-C15 : 0, iso-C15 : 0, iso-C14 : 0, iso-C16 : 0 and C16 : 0. The chemotaxonomic properties of BG109T were generally consistent with those of members of the genus Metabacillus. BG109T shared highest 16S rRNA gene sequence similarities with 'Metabacillus elymi' KUDC1714 (99.26 %), Metabacillus sediminilitoris DSL-17T (98.17 %), Metabacillus litoralis SW-211T (98.16 %) and Metabacillus crassostreae JSM 100118T (97.13 %), all of which were well below the suggested cutoff level for species distinction. The genome level relatedness also confirmed the separation of BG109T from other species of the genus Metabacillus. Thus, it is evident that BG109T merits recognition as representing a novel species of the genus Metabacillus, for which the name Metabacillus bambusae sp. nov. is proposed. The type strain is BG109T (=KCTC 43190T=JCM 34515T).
