Adhaeribacter terrae sp. nov., a novel bacterium isolated from soil

Strain HY02^Twas isolated from a soil sample collected at Namyangju-si, Gyeonggi-do, Republic of Korea. Cells of this strain were observed to be Gram-stain-negative, short and rod-shaped. Colonies were red in colour. A 16S rRNA gene sequence analysis identified this strain as a member of the genus Adhaeribacter in the family Cytophagaceae, with the highest level of 16S rRNA gene sequence similarity to Adhaeribacter terreus DNG6^T(98.08 %). This strain was positive for oxidase but negative for catalase activity and acid production from glucose. Growth of strain HY02^Twas observed at 15–30 °C, pH 7–8 and in the presence of 0–1%NaCl. The isolate contained MK-7 as the predominant respiratory quinone, and C_{18: 0}, iso-C_{15: 0}, summed feature 4 (anteiso-C_{17: 1}B/iso-C_{17: 1}I) and C_{16: 0}were the major fatty acids. The major polar lipid was phosphatidylethanolamine. The genomic DNA G+C content of strain HY02^Twas 44.0 mol%. Phenotypic and chemotaxonomic data supported the affiliation of strain HY02^Twith the genus Adhaeribacter. However, strain HY02^Texhibited a relatively low level of DNA–DNA relatedness with A. terreus (16.3±3.5 %). Based on its phenotypic and genotypic properties, together with its phylogenetic distinctiveness, strain HY02^Tshould be considered a representative of a novel species in the genus Adhaeribacter, for which the name Adhaeribacter terrae sp. nov. is proposed. The type strain is HY02^T(=KCTC 52512^T=JCM 31652^T).
