ABSTRACT
A pink-pigmented bacterium, designated as strain SYSU D00476T, was isolated from sandy soil collected from the Kumtag Desert in China. Colonies were opaque, smooth and of a slight convexity with a clearly defined border. Cells were rod-shaped, Gram-stain-negative, catalase- and oxidase-positive. Growth occurred at 4-45 â (optimum at 28-30 â), pH 6.0-8.0 (optimum at 7.0), and with 0-3.0% NaCl (w/v, optimum at 0-2.0%). Major fatty acids (> 10%) were C160, summed feature 3 (C161 ω7c and/or C161 ω6c), iso-C170 3-OH and iso-C150. Polar lipids comprised of three unidentified polar aminolipids (ALs), two unidentified aminophosphoglycolipids (APLs), one unidentified glycolipid (GL) and three unidentified phospholipids (PLs). The predominant respiratory quinone was MK-7. The genomic DNA G + C content was 50.5%. The low digital DNA-DNA hybridization (dDDH, 27.4%) and average nucleotide identity (ANI, 85%) values between strain SYSU D00476T and Telluribacter humicola KCTC 42819T indicated that SYSU D00476T represent a distinct species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SYSU D00476T belonged to the genus Telluribacter, showing 97.5% similarity with T. humicola KCTC 42819T. All these data support that strain SYSU D00476T represent a novel species of the genus Telluribacter within the family Spirosomataceae, named as Telluribacter roseus sp. nov. The type strain is SYSU D00476T (= KCTC 82285T = CGMCC 1.18647T = MCCC 1K04983T).
