| Abstract |
A Gram-stain-positive, aerobic, non-motile, non-spore-forming, short rod-shaped actinobacterium, designated strain PB243(T), was isolated from grass soil sampled in Daejeon, Republic of Korea. Comparative 16S rRNA gene sequence studies showed the isolate was clearly affiliated with the class Actinobacteria, and most closely related to Amnibacterium kyonggiense KEMC 51201-037(T), showing 98.8 % 16S rRNA gene sequence similarity. Cells of strain PB243(T) formed yellow colonies on R2A agar, contained MK-11 and MK-12 as the predominant menaquinones, l-2,4-diaminobutyric acid as the diagnostic cell-wall diamino acid, and anteiso-C15:0 and iso-C16:0 among the major fatty acids. The acyl type of the muramic acid was acetyl. The G+C content of the genomic DNA of strain PB243(T) was 71.5 mol%. Thus, the combined genotypic and phenotypic data supported the conclusion that strain PB243(T) represents a novel species of the genus Amnibacterium, for which the name Amnibacterium soli sp. nov. is proposed. The type strain is PB243(T) ( = KCTC 33147(T) = JCM 19015(T)).
