title: Orbus sasakiae sp. nov., a bacterium isolated from the gut of the butterfly Sasakia charonda, and emended description of the genus Orbus.
abstract: A novel Gram-stain-negative, facultatively anaerobic, non-motile and coccus-shaped bacterium, strain C7(T), was isolated from the gut of the butterfly Sasakia charonda. Strain C7(T) grew optimally at 20-25 °C, at pH 7-8 and with 1 % (w/v) NaCl. The strain was negative for oxidase activity but positive for catalase activity. The 16S rRNA gene sequences of strain C7(T) and Orbus hercynius CN3(T) shared 96.8 % similarity. The major fatty acids identified were C14 : 0, C16 : 0, C18 : 1ω7c and summed feature 2 (comprising C14 : 0 3-OH/iso-C16 : 1). The major respiratory quinone was ubiquinone-8 (Q-8). The polar lipids of strain C7(T) were phosphatidylethanolamine, phosphatidylglycerol, an unidentified phospholipid and two unidentified aminophospholipids. The G+C content of the genomic DNA extracted from strain C7(T) was 32.1 mol%. Taken together, the phenotypic, genotypic and phylogenetic analyses indicate that strain C7(T) represents a novel species of the genus Orbus, for which the name Orbus sasakiae sp. nov. is proposed. The type strain is C7(T) ( = KACC 16544(T) = JCM 18050(T)). An emended description of the genus Orbus is provided.
