Burkholderia soli sp. nov., isolated from soil cultivated with Korean ginseng

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, GP25-8T, grew optimally at pH 6–7, 28 °C and 0–1 % NaCl (w/v). The major fatty acids were C18 : 1 ω7c, summed feature 3 (C16 : 1 ω7c/C15 : 0 iso 2-OH) and C16 : 0 (together representing 71.2 % of the total). The 16S rRNA gene sequence similarities between strain GP25-8T and members of the genus Burkholderia 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 Burkholderia caryophylli ATCC 25418T (97.4 %) and Burkholderia phenazinium LMG 2247T (97.2 %); the levels of DNA–DNA hybridization with these strains were 28 and 12 %, respectively. These results support the conclusion that strain GP25-8T represents a novel species within the genus Burkholderia, for which the name Burkholderia soli sp. nov. is proposed. The type strain is GP25-8T (=KACC 11589T=DSM 18235T).
