Flaviaesturariibacter aridisoli sp. nov., A Bacterium Isolated from Dry Soil

A novel bacterial strain, designated 17J68-15^T, was isolated from dry soil collected in Jeju Island, South Korea. Cells of strain 17J68-15^T are Gram-negative, pale-yellow-colored, non-motile, non-spore-forming, rod-shaped was able to grow at 18-42 °C with 0-1% NaCl on R2A agar. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain was distinct from any previously known species of the genus Flaviaesturariibacter. The highest degrees of 16S rRNA gene sequence similarity found with Flaviaesturariibacter terrae HY03^T (97.6%), Flaviaesturariibacter amylovorans (96.2%) and Flaviaesturariibacter luteus AW305^T (96.0%). The DNA G + C content of the novel strain, 17J68-15^T, was 9.3 mol%. Chemotaxonomic data revealed that the major fatty acids were iso-C_15:0, iso-C_15:1 G, iso-C_17:0 3-OH and summed feature 3 (C_16:1 ω6c and/or C_16:1 ω7c); the major polar lipid was identified as phosphatidylethanolamine, and the major quinone was identified as MK-7. Based on polyphasic characterization, strain 17J68-15^T represents a novel species of the genus Flaviaesturariibacter for which the name Flaviaesturariibacter aridisoli sp. nov. is proposed, with the type strain 17J68-15^T (= KCTC 62220^T = JCM 19635^T).
