A polyphasic study was carried out to clarify the taxonomic position of a Gram-negative bacterium isolated from soil cultivated with Korean ginseng in the Eumseong region of Korea. The novel strain, GP25-8, grew optimally at pH 6–7, 28 °C and 0–1 % NaCl (w/v). The major fatty acids were C 7, summed feature 3 (C 7/C iso 2-OH) and C (together representing 71.2 % of the total). The 16S rRNA gene sequence similarities between strain GP25-8 and members of the genus ranged from 94.7 to 97.4 %, indicating that this novel strain was phylogenetically related to members of that genus. The novel strain showed the highest sequence similarities to ATCC 25418 (97.4 %) and LMG 2247 (97.2 %); the levels of DNA–DNA hybridization with these strains were 28 and 12 %, respectively. These results support the conclusion that strain GP25-8 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is GP25-8 (=KACC 11589=DSM 18235).
