Abstract

Two bacterial isolates from ginseng fields in Korea, strains GR17-7 and GP18-1, were characterized using a polyphasic approach. Phylogenetic analysis of their 16S rRNA gene sequences revealed a clear affiliation with the , and showed that the closest phylogenetic relationships were with members of the genus . The 16S rRNA gene sequence similarity between strains GR17-7 and GP18-1 was 97.2 %. Both strains showed 16S rRNA gene sequence similarities of 95.2–96.9 % to type strains of recognized species. The G+C contents of the DNA of strains GR17-7 and GP18-1 were 61.0 and 62.5 mol%, respectively. According to the DNA–DNA hydridization tests, the hybridization value between strains GR17-7 and GP18-1 was 34 %. Strains GR17-7 and GP18-1 showed less than 32 % DNA–DNA relatedness with KCTC 12098 and LMG 23181. Strains GR17-7 and GP18-1 were aerobic, Gram-negative, rod-shaped, and catalase- and oxidase-positive. Major fatty acids of both strains were iso-C 9 and iso-C. Based on the data presented, two novel species are proposed, with the names sp. nov. (type strain GR17-7=KACC 11762=DSM 18993) and sp. nov. (type strain GP18-1=KACC 11761=DSM 19241).
