Abstract

A bacterial strain, PSGM2-16, 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 PSGM2-16 revealed the highest sequence similarities with DMZ1 (97.4 %), YIM C003 (97.2 %) and R-Ac013 (97.0 %), and the phylogenetic tree showed that strain PSGM2-16 formed a subgroup with HB09001 and YIM C003 within the family . The major fatty acids (>10 % of the total fatty acids) of strain PSGM2-16 were iso-C, Cω8 and iso-C. The predominant menaquinone was MK-8(H). The polar lipids present were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, three aminophospholipids and two phospholipids. The peptidoglycan was type A4γ with -diaminopimelic acid as the diagnostic diamino acid. DNA–DNA hybridization values between strain PSGM2-16 and closely related taxa were much less than 70 %. The genomic DNA G+C content of strain PSGM2-16 was 70.0 mol%. On the basis of the evidence presented, it is concluded that strain PSGM2-16 represents a novel species of a new genus in the family , for which the name gen. nov., sp. nov. is proposed. The type strain of the type species is PSGM2-16 ( = KACC 17299 = DSM 27137 = NBRC 109598).
