Two actinomycete strains, ID05-A0653(T) and ID06-A0464(T), were isolated from soils of West Timor and Lombok island, respectively, in Indonesia. 16S rRNA gene sequence analysis clearly demonstrated that the isolates belonged to the family Pseudonocardiaceae and were closely related to the genus Actinophytocola. Strains ID05-A0653(T) and ID06-A0464(T). exhibited 98.1 and 98.2% 16S rRNA gene sequence similarity, respectively, with Actinophytocola oryzae GMKU 367(T). The isolates grew well on ISP media and produced white aerial mycelium. Short spore chains were formed directly on the substrate mycelium. The isolates contained mesodiaminopimelic acid, arabinose and galactose as cell-wall components, MK-9(H(4)) as the sole isoprenoid quinone, iso-C(16:0) as the major cellular fatty acid and phosphatidylethanolamine as the diagnostic polar lipid. The DNA G+C contents of strains ID05-A0653(T) and ID06-A0464(T) were 69.7 and 71.2 mol%, respectively. On the basis of phenotypic characteristics, DNA-DNA relatedness and 16S rRNA gene sequence comparisons, strains ID05-A0653(T) and ID06-A0464(T) each represent a novel species of the genus Actinophytocola, for which the names Actinophytocola timorensis sp. nov. (type strain ID05-A0653(T) =BTCC B-673(T) =NBRC 105524(T)) and Actinophytocola corallina sp. nov. (type strain ID06-A0464(T) =BTCC B-674(T) =NBRC 105525(T)) are proposed.
