ABSTRACT
A Gram-stain-negative, non-motile, coccobacillus-shaped bacterium, designated CPCC 101021T, was isolated from a sandy soil sample collected from Badain Jaran desert, China. Its 16S rRNA gene sequence was closely related to those of members of the genus Roseomonas, showing high similarities with Roseomonas hibiscisoli THG-N2.22T (98.0â%), Roseomonas oryzae KCTC 42542T (97.9â%), Roseomonas rhizosphaerae YW11T (97.9 %) and Roseomonas suffusca S1T (97.8â%). In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 101021T formed a distinct subclade with R. oryzae KCTC 42542T within the genus Roseomonas. Growth of the isolate occurred at 15-37 °C and pH 6.0-8.5, with optimal growth at 30 °C and pH 7.0. The major cellular fatty acids were C18ââ1ω7c, summed feature 8 (C16ââ1ω7c/C16ââ1ω6c), summed feature 3 (C16ââ1ω6c/C16ââ1ω7c) and C16ââ0ω6c. Q-10 was detected as the main component in the respiratory quinone system, with Q-9 as a minor component. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, an unidentified phospholipid, an unidentified aminolipid and an unidentified glycolipid were found in the polar lipid profile. The genomic DNA G+C content was 68.7 mol%. The average nucleotide identity was 84.6â% when comparing the draft genome sequences of strain CPCC 101021T with R. oryzae KCTC 42542T. On the basis of genotypic, chemotaxonomic and phenotypic characteristics, strain CPCC 101021T is proposed to represent a novel species of the genus Roseomonas with the name Roseomonas vastitatis sp. nov. Strain CPCC 101021T (=J1A743T=KCTC 62043T) is the type strain of the species.
