Lysobacter panacisoli sp nov., isolated from ginseng soil

초록

A novel bacterial strain, designated CJ29(T), was isolated from ginseng soil of Anseong in South Korea. Cells of strain CJ29(T) were Gram-stain-negative, facultatively anaerobic, rod-shaped and non-motile. Strain CJ29(T) grew optimally at 28-30 degrees C and pH 7.0. Based on 16S rRNA gene sequence analysis, strain CJ29T was shown to belong to the genus Lysobacter within the class Gammaproteobacteria and was related most closely to Lysobacter soli DCY21(T) (98.5% similarity) and Lysobacter niastensis GH41-7(T) (98.2%). DNA-DNA relatedness between strain CJ29(T) and its closest relatives was below 55.6%. The predominant cellular fatty acids of strain CJ29(T) were iso-C-15:0, iso-C-16:0 and iso-C-17:1 omega 9c. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The major isoprenoid quinone was ubiquinone 8 (Q-8). The G C content of the genomic DNA was 65.6 mol%. Phenotypic, genotypic and phylogenetic characteristics strongly supported the differentiation of strain CJ29(T) from related species of the genus Lysobacter. On the basis of data from this polyphasic taxonomic study, strain CJ29(T) is considered to represent a novel species of the genus Lysobacter, for which the name Lysobacter panacisoli sp. nov. is proposed. The type strain is CJ29(T) (=KACC 17502(T)=JCM 19212(T)).
