A gram-negative bacterium, designated FJY1(T), was isolated from a soil sample obtained from a university campus in South Korea. Examination showed that FJY1(T) was red-pigmented, aerobic, motile, and composed of nonspore-forming rods. This strain grew in a temperature range of 15-37 °C and a pH range of 7-9. Based on 16S rRNA gene sequence similarity, strain FJY1(T) was most closely related to Rufibacter roseus H359(T) and Rufibacter tibetensis 1351(T), with sequence similarities of 95.98 and 95.46 %, respectively. Its major cellular fatty acids were iso-C15:0 (18.16 %) and summed feature 4 (C17:1 iso I and C17:1 anteiso B; 15.17 %). The DNA G+C content of FJY1(T) was 49.7 mol%; its predominant quinone was MK-7; and its major polar lipid was phosphatidylethanolamine. Phylogenetic analysis and analysis of its physiological and biochemical characteristics indicated that this isolate constituted a novel species, for which we propose the name Rufibacter soli sp. nov., with the type strain FJY1(T) (=KCTC 42815(T) = JCM 31024(T)).
