- Two strains, PB34T and PB261T, were isolated from grass soil sampled in Daejeon, Republic of Korea. Comparative 16S rRNA gene sequence studies showed the two bacteria to be clearly affiliated with the phylum Actinobacteria and most closely related to the genus Geodermatophilus, showing 16S rRNA gene sequence similarities to the type strains of species of the genus Geodermatophilus of 95.0-96.3 % and sharing 98.5 % similarity between the two strains. The two strains were Gram-stain-positive, aerobic, motile and rod-shaped bacteria. The peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinones were MK-9(H4) and MK-9(H0). The major fatty acids were iso-C15: 0, iso-C16: 0, iso-C17: 0 and summed feature 3 (C16: 1ω7c and/or C16: 1ω6c) for strain PB34T and iso-C14: 0, iso-C15: 0, iso-C16: 0 and C16: 0 for strain PB261T. The G+C contents of the genomic DNA of strains PB34T and PB261T were 73.2 mol% and 74.1 mol%, respectively. Thus, based on the evidence of a polyphasic study, it is proposed that strains PB34T and PB261T represent two novel species, for which the names Geodermatophilus soli sp. nov. (type strain PB34T = KCTC 19880T = JCM 17785T) and Geodermatophilus terrae sp. nov. (type strain PB261T = KCTC 19881T = JCM 17786T) are proposed.
