sp. nov., isolated from desert soil Free

Abstract

A gamma- and UV radiation-tolerant, Gram-negative, short-rod-shaped bacterial strain, designated X-121, was isolated from soil samples collected from the Taklimakan desert in Xinjiang, China. Strain X-121 showed the highest 16S rRNA gene sequence similarity with TDMA-24 (94.7 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain X-121 is a member of a novel species belonging to the clade formed by members of the genus in the family The DNA G+C content of strain X-121 was 63.6 mol%. The chemotaxonomic charateristics of strain X-121 were typical of members of the genus , with MK-8 being the predominant respiratory quinone, summed feature 3 (16 : 1ω7,16 : 1ω6), 16 : 0 and 17 : 1ω8 as major cellular fatty acid, several unidentified phosphoglycolipids and glycolipids as the dominant polar lipids, galactose as the predominant cell-wall sugar and the presence of peptidoglycan with -ornithine. Strain X-121 is therefore identified as representing a novel species, for which the name sp. nov. is proposed, with the type strain X-121(=CCTCC AB 207228=KCTC 33842).
