Abstract

A bacterial strain, designated T20R-70, was isolated from tomato rhizosphere soil collected in Yecheon-gun, Gyeongsangbuk-do in South Korea. Growth was observed within the ranges 10–40 °C (optimally at 28–30 °C), pH 7.0–8.0 (optimally at pH 7.0) and 0–1 % NaCl (optimally at 0 %). The 16S rRNA gene sequence showed the highest similarities with those of KTCe-2 (98.7 %), KCTC 12130 (98.0 %), ‘' Dae08 (97.2 %) and 107-E2 (97.1 %). The phylogenetic tree showed that strain T20R-70 formed a clade with KTCe-2 and KCTC 12130. The dominant fatty acids (>10 %) were iso-C, iso-C, iso-Cω9 and summed feature 3 (including iso-C 2-OH and/or iso-Cω7). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The major respiratory quinone was Q-8. DNA–DNA hybridization data revealed that strain T20R-70 had a hybridization value of 42±4 % (mean±) to the most closely related species of the genus . The DNA G+C content was 63.0 mol%. The physiological, biochemical and chemotaxonomic data allowed the discrimination of the new isolate from its phylogenetic relatives. Strain T20R-70 is thus considered to be a representative of a novel species of the genus , for which the name sp. nov. is proposed. The type strain is T20R-70 (=KACC 18656=NBRC 111881).
