Description of Tellurirhabdus bombi sp. nov., Isolated from Bumblebee

Abstract

A Gram-stain-negative, aerobic, non-motile, and rod-shaped bacterium, designated IE-0392^T, was isolated from a bumblebee. The 16S rRNA gene sequence (highest 16S rRNA gene sequence similarity with the type strain of Tellurirhabdus rosea (90.0%) and phylogenetic analysis suggest that strain IE-0392^T was a member of the genus Tellurirhabdus. Strain IE-0392^T optimally grew at 25 ℃ and pH 7.0. Menaquinone 7 (MK-7) was the only isoprenoid quinone present in strain IE-0392^T. The major fatty acids (> 10%) of strain IE-0392^T were iso-C_15:0, C_16:1 ω5c, and iso-C_17:0 3-OH. The polar lipids of strain IE-0392^T were phosphatidylethanolamine, phosphatidylserine, unidentified aminophospholipids, unidentified aminolipid, unidentified phospholipid, and unidentified lipids. The genomic DNA G + C content of strain IE-0392^T was 48.8%. The amino acid identity (AAI) and the average nucleotide identity (ANI) values suggest that strain IE-0392^T is a novel member of the genus Tellurirhabdus. The results suggest that strain IE-0392^T represents a novel species of the genus Tellurirhabdus, for which the name Tellurirhabdus bombi sp. nov., is proposed. The type strain is IE-0392^T (= GDMCC 1.2794^T = JCM 35040^T).
