| Abstract |
A novel bacterial strain DCY89(T) was isolated from soil sample of ginseng field and was characterized using a polyphasic approach. Cells were Gram-reaction-positive, rod-shaped, spore-forming and motile with flagella. The strain was aerobic, esculin and starch positive, catalase- and oxidase-negative, optimum growth temperature, and pH were 25-30 °C and 6.0-7.5, respectively. On the basis of 16S rRNA gene sequence analysis, strain DCY89(T) was shown to belong to the genus Paenibacillus and the closest phylogenetic relatives were Paenibacillus cellulosilyticus KACC 14175(T) (98.2%), Paenibacillus kobensis KACC 15273(T) (98.1%), Paenibacillus xylaniclasticus KCTC 13719(T) (96.9%), and Paenibacillus curdlanolyticus KCTC 3759(T) (96.64%). The DNA G+C content was 52.5 mol%, and the predominant respiratory quinone was MK-7. The major fatty acids were iso-C15:0, iso-C16:0, and anteiso-C15:0. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. The results of the genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that DCY89(T) represented a novel species within the genus Paenibacillus, for which we propose the name Paenibacillus ginsengiterrae. The type strain is DCY89(T) (JCM 19887(T) = KCTC 33430(T)).
