Abstract

A Gram-negative, yellow-colored, rod-shaped, strictly aerobic, motile bacterium was isolated from forest soil in Gyeongsang Province, South Korea. The strain was designated as THG-DA2.1(T). Cells of strain THG-DA2.1(T) grew optimally at pH 7.0, at temperature 28 °C and in the presence of 0.5 % NaCl. Based on 16S rRNA gene sequence, strain THG-DA2.1(T) was shown to belong to the genus Pedobacter and shares highest sequence similarity with Pedobacter ginsengisoli KCTC 12576(T). The DNA G+C content was determined to be 42.3 mol %. The predominant isoprenoid quinone was identified as menaquinone MK-7. The major cellular fatty acids of strain THG-DA2.1(T) were iso-C15:0 and C16:1 ω6c and/or C16:1 ω7c (summed feature 3*). Strain THG-DA2.1(T) contains phosphatidylethanolamine as major polar lipid, but an unidentified aminolipid, two unidentified phospholipids and two unidentified lipids were also detected. On the basis of the data obtained from polyphasic taxonomy in this study, strain THG-DA2.1(T) is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter edaphicus sp. nov. is proposed. The type strain is THG-DA2.1(T) (=KCTC 42232(T) =JCM 30351(T)).
