Actinoallomurus radicium sp nov., isolated from the roots of two plant species

Three strains, K08-0182(T), K08-0178 and K08-0195 were isolated from the paste of ground plant roots collected in Kanagawa Prefecture, Japan. These strains contained meso-diaminopimelic acid and lysine as the diamino acids in cell-wall peptidoglycan, and MK-9(H-6) and MK-9(H-8) as the predominant menaquinones. The G+C contents of the DNA were 72-73 mol%. Taken together, these characteristics combined with 16S rRNA gene sequence analyses revealed that the isolated strains belong to the genus Actinoallomurus. DNA DNA hybridization values showed that the three strains belonged to a novel species of the genus Actinoallomurus. Therefore strains K08-0182(T), K08-0178 and K08-0195 are proposed as representatives of a novel species, Actinoallomurus radicium sp. nov. The type strain is K08-0182(T) (=DSM 45523(T) =NBRC 107678(T) =JCM 17294(T)).
