Abstract

A Gram-stain-negative, strictly aerobic, rod-shaped and pinkish-yellow bacterium, which was motile by gliding and designated strain THG–T11, was isolated from tomato rhizosphere soil in Gyeonggi province, Republic of Korea. Based on 16S rRNA gene sequence comparisons, strain THG-T11 was found to be most closely related to ‘Pedobacter ’ TDMA-5 (95.9 % sequence similarity), PB92 (94.9 %), 01-96 (94.6 %) and NWER-II11 (94.5 %). The DNA G+C content was 38.4 mol%. The only isoprenoid quinone detected in strain THG-T11 was menaquinone-7 (MK-7). The major component in the polyamine pattern was -homospermidine. The major polar lipids were phosphatidylethanolamine, an unidentified phosphoglycolipid, an unidentified glycolipid, an unidentified lipid, unidentified aminophospholipids and unidentified aminolipids. The major ceramide was found to be ceramide phosphorylethanolamine. The major fatty acids were identified as iso-C, summed feature 3 (Cω7 and/or Cω6) and C. These data support the affiliation of strain THG-T11 to the genus . Based on phenotypic, chemotaxonomic and phylogenetic analysis, it is proposed that strain THG-T11 represents a novel species of the genus for which the name sp. nov. is proposed, with THG-T11 as the type strain ( = KACC 17660 = JCM 19461).
