Abstract

A Gram-negative, pink-coloured, rod-shaped, motile bacterium, designated YIM 93097(T), was isolated from the desert soil collected from Xinjiang province of China. Strain YIM 93097(T) was found to grow at 20-45 °C (optimum 28-37 °C), pH 5.0-7.0 (optimum pH 7.0) and 0-8 % (w/v) NaCl (optimum 1 %, w/v). Based on 16S rRNA gene sequence similarity studies, it belongs to the genus Skermanella. The 16S rRNA gene sequence similarity was identified to be 98.7 % to Skermanella xinjiangensis CCTCC AB 207153(T) while the DNA-DNA hybridization value was found to be only 48.1 %. The predominant isoprenoid quinone was determined to be Q-10. The major fatty acids were identified to be C16:0, C18:1 ω7c and summed feature 4 (consisting of C17:1 anteiso B/iso I). The major polar lipids were identified as phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, two unidentified phospholipids and one unidentified aminolipid. The DNA G+C content was found to be 67.2 mol %. The analysis of the genotypic and phenotypic data indicated that strain YIM 93097(T) belongs to a novel species of the genus Skermanella, for which the name Skermanella rubra sp. nov. is proposed. The type strain is YIM 93097(T) (=DSM 21389(T)=CCTCC AB 2015161(T)).
