چکیده

A novel bacterial strain DCY53(T) was isolated from a soil sample from a ginseng field and was characterized using a polyphasic approach. Cells were Gram-reaction-positive, rod-shaped, endospore-forming and motile with flagella. The strain was aerobic, catalase- and oxidase-positive, optimum growth temperature and pH were 30-37 °C and 6.0-7.5, respectively. On the basis of 16S rRNA gene sequence analysis, strain DCY53(T) was shown to belong to the genus Bacillus and the closest phylogenetic relatives were Bacillus pocheonensis KCTC 13943(T) (98.3 %), Bacillus bataviensis LMG 21833(T) (98.0 %), Bacillus soli LMG 21838(T) (97.9 %), Bacillus drentensis LMG 21831(T) (97.8 %), Bacillus niacini DSM 2923(T) (97.8 %), Bacillus novalis LMG 21837(T) (97.7 %), Bacillus vireti LMG 21834(T) (97.6 %) and Bacillus fumarioli LMG 17489(T) (97.3 %). The DNA G+C content was 43.6 mol% and the predominant respiratory quinone was MK-7. The major fatty acids were iso-C14 : 0, iso-C15 : 0, iso-C16 : 0 and anteiso-C15 : 0. The DNA-DNA relatedness with closest relatives was below 55 %. The results of the genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that DCY53(T) represented a novel species within the genus Bacillus, for which we propose the name Bacillus ginsengisoli. The type strain is DCY53(T) ( = KCTC 13945(T) = JCM 17335(T)).
