Abstract

Strain HY02 was 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 (98.08 %). This strain was positive for oxidase but negative for catalase activity and acid production from glucose. Growth of strain HY02 was 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 C18 : 0, iso-C15 : 0, summed feature 4 (anteiso-C17 : 1 B/iso-C17 : 1 I) and C16 : 0 were the major fatty acids. The major polar lipid was phosphatidylethanolamine. The genomic DNA G+C content of strain HY02 was 44.0 mol%. Phenotypic and chemotaxonomic data supported the affiliation of strain HY02 with the genus Adhaeribacter . However, strain HY02 exhibited 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 should 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 (=KCTC 52512=JCM 31652).
