Kurzfassung:
A Gram-negative, aerobic, rod-shaped, motile Brevundimonas -like bacterial strain, J22 T , was isolated from black sand collected from Soesoggak, Jeju Island, Korea. Growth of strain J22 T was observed in R2A medium at temperatures between 10 and 42 °C (optimum 30 °C), between pH 6.5 and 10.5 (optimum pH 7.5) and at a NaCl concentration between 0 and 4 % (w/v) (optimum 0–1 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain J22 T belonged to the genus Brevundimonas , with high sequence similarities of 〉 97 % to the sequence of the type strains Brevundimonas alba CB88 T , Brevundimonas lenta DS-18 T , Brevundimonas variabilis CB17 T , Mycoplana bullata TK0051 T , Brevundimonas kwangchunensis KSL-102 T , Brevundimonas intermedia CB63 T , Brevundimonas subvibrioides CB81 T and Brevundimonas bacteroides CB7 T . Strain J22 T exhibited DNA–DNA relatedness values of less than 22.2 % with the phylogenetically related species of the genus Brevundimonas . The DNA G+C content of strain J22 T was 66.3 mol%. The predominant cellular fatty acids were C 18 : 1 ω 7 c , C 16 : 0 and C 16 : 1 ω 9 c ; C 12 : 0 3-OH was present, which chemotaxonomically characterizes the members of the genus Brevundimonas . Phylogenetic, genomic and biochemical characteristics served to differentiate this isolate from recognized members of the genus Brevundimonas . Strain J22 T (=KCTC 22177 T =JCM 15911 T ) should be classified as a novel species in the genus Brevundimonas , for which the name Brevundimonas basaltis sp. nov. is proposed.
