Abstract

A novel Gram-stain-negative, aerobic, oxidase-positive, catalase-positive, non-motile, short rod-shaped, red-pigmented strain, designated as SYSU D00434, was isolated from a dry sandy soil sample collected from the Gurbantunggut desert in Xinjiang, north-west PR China. Strain SYSU D00434 was found to grow at 4–37 °C (optimum, 28–30 °C), pH 6.0–8.0 (optimum, pH 7.0) and with 0–1.5 % (w/v) NaCl (optimum, 0–0.5 %). The predominant respiratory quinone was MK-7 and the major fatty acids (>10 %) were C 5, iso-C, summed feature 3 (C 6 and/or C 7) and summed feature 4 (anteiso-C B and/or iso-C I). The polar lipids consisted of phosphatidylethanolamine, two unidentified polar lipids, two unidentified aminolipids, two unidentified phospholipids and two unidentified glycolipids. The genomic DNA G+C content of strain SYSU D00434 was 50.6 mol%. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain SYSU D00434 belonged to the family , and shared a sequence similarity of less than 94.6 % to all validly named taxa. Based on the phenotypic, phylogenetic and chemotaxonomic properties, strain D00434 is proposed to represent a new species of a new genus, named gen. nov., sp. nov., within the family . The type strain is SYSU D00434 (=CGMCC 1.18624=KCTC 82276=MCCC 1K04975).
