| Abstract |
A yellow, aerobic, Gram-stain-negative, non-motile, rod-shaped and non-flagellated bacterial strain, designated T16R-129T, was isolated from the rhizosphere of a tomato plant collected at a farm located on Buyeo-gun of Chungcheongnam-do, South Korea. Strain T16R-129T grew at 15-40 °C and pH 7.0-9.0, and did not require NaCl for growth. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain T16R-129T clustered with members of the genus Terrimonas, and it shared highest similarity with Terrimonas arctica R9-86T (96.1 %), Terrimonas pekingensis QHT (95.9 %), Terrimonas lutea DYT (94.9 %), Terrimonas crocea M1-33108T (95.4 %) and Terrimonas rhizosphaerae CR94T (95.3 %). The major isoprenoid quinone was menaquinone 7 (MK-7). The major cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G. The polar lipids of strain T16R-129T were phosphatidylethanolamine, two unidentified aminolipids, two unidentified aminophospholipids and five unidentified polar lipids. The G+C content of the genomic DNA was 46.0 mol%. On the basis of data from this polyphasic taxonomic study, strain T16R-129T represents a novel species in the genus Terrimonas, for which the name Terrimonas terrae sp. nov. is proposed; the type strain is T16R-129T (=KACC 18787T=JCM 31603T).
