Caenimonas soli sp. nov., isolated from soil

A non-motile, Gram-stain-negative, rod-shaped bacterium, designated strain S4 T , was obtained from soil sampled at Wonju, Gyeonggi-do, Republic of Korea. Cells were white-coloured, aerobic, grew optimally at 25–32 °C on R2A agar plate. A phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain S4 T formed a lineage within the family Comamonadaceae . The closest members were Caenimonas terrae SGM1–15 T (98.1% sequence similarity), Caenimonas koreensis EMB320 T (97.5%) and Ramlibacter solisilvae 5–10 T (97.8%). The sequence similarities of strain S4 T with other members of the family Comamonadaceae were ≤ 97.5%. The sole respiratory quinone was ubiquinone-8 (Q-8) and the principal polar lipid was phosphatidylethanolamine. The predominant cellular fatty acids were summed feature 3 (iso-C 15 :0 2-OH/C 16 :1 ω 7 c ), C 16:0 and summed feature 8 (C 18:1 ω 7 c and/or C 18:1 ω 6 c ). The DNA G + C content was 65.1 mol%. In addition, the average nucleotide identity (ANIu) and in silico DNA–DNA hybridization (dDDH) relatedness values between strain S4 T and Caenimonas koreensis were 77.6 and 21%, respectively. Based on genomic, chemotaxonomic, phenotypic, and phylogenetic analyses, strain S4 T represents a novel species in the genus Caenimonas , for which the name Caenimonas soli sp. nov. is proposed. The type strain is S4 T (= KCTC 72742 T = NBRC 114610 T ).
