Strain HY02(T) 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(T) (98.08 %). This strain was positive for oxidase but negative for catalase activity and acid production from glucose. Growth of strain HY02(T) was observed at 15-30 degrees 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(T) was 44.0 mol%. Phenotypic and chemotaxonomic data supported the affiliation of strain HY02(T) with the genus Adhaeribacter. However, strain HY02(T) 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(T) 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(T) (=KCTC 52512(T) = JCM 31652(T)).
