| Popis: | A novel orange-coloured bacterium, designated strain SYSU D00508T, was isolated from a sandy soil sampled from the Kumtag Desert in China. Strain SYSU D00508T was aerobic, Gram-stain-negative, oxidase-positive, catalase-positive and non-motile. Growth occurred at 4–45°C (optimum 28–30°C), pH 6.0–9.0 (optimum pH 7.0–8.0) and with 0–2.5 % NaCl (w/v, optimum 0–1.0 %). The major polar lipids consisted of phosphatidylethanolamine (PE), unidentified aminolipids (AL1-3) and unidentified polar lipids (L1-5) were also detected. The major respiratory quinone was MK-7 and the major fatty acids (>10 %) were iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 1 G. The genomic DNA G+C content was 42.6 %. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SYSU D00508T belonged to the family Chitinophagaceae and showed 93.9 % ( Segetibacter koreensis DSM18137T), 92.9 % ( Segetibacter aerophilus NBRC 106135T), 93.0 % ( Terrimonas soli JCM 32095T) and 92.8 % ( Parasegetibacter terrae JCM 19942T) similarities. Based on the phylogenetic, phenotypic and chemotaxonomic data, strain SYSU D00508T is proposed to represent a novel species of a new genus, named Aridibaculum aurantiacum gen. nov., sp. nov., within the family Chitinophagaceae . The type strain is SYSU D00508T (=KCTC 82286T=CGMCC 1.18648T=MCCC 1K05005T). |
