A bacterial strain, PSGM2-16T, was isolated from a pot of paddy soil grown with rice in Suwon region, Republic of Korea, and was characterized as having aerobic, Gram-stain-positive, short-rod-shaped cells with one polar flagellum. The 16S rRNA gene sequence of strain PSGM2-16T revealed the highest sequence similarities with Knoellia locipacati DMZ1T (97.4 %), Fodinibacter luteus YIM C003T (97.2 %) and Lapillicoccus jejuensis R-Ac013T (97.0 %), and the phylogenetic tree showed that strain PSGM2-16T formed a subgroup with Ornithinibacter aureus HB09001T and F. luteus YIM C003T within the family Intrasporangiaceae. The major fatty acids (>10 % of the total fatty acids) of strain PSGM2-16T were iso-C16 : 0, C17 : 1ω8c and iso-C14 : 0. The predominant menaquinone was MK-8(H4). The polar lipids present were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, three aminophospholipids and two phospholipids. The peptidoglycan was type A4γ with meso-diaminopimelic acid as the diagnostic diamino acid. DNA–DNA hybridization values between strain PSGM2-16T and closely related taxa were much less than 70 %. The genomic DNA G+C content of strain PSGM2-16T was 70.0 mol%. On the basis of the evidence presented, it is concluded that strain PSGM2-16T represents a novel species of a new genus in the family Intrasporangiaceae, for which the name Oryzobacter terrae gen. nov., sp. nov. is proposed. The type strain of the type species is PSGM2-16T ( = KACC 17299T = DSM 27137T = NBRC 109598T).
