| Abstract |
A Gram-stain negative, non-motile, rod-shaped, aerobic bacterium, designated 15J8-8T, was isolated from a soil sample collected on Jeju Island, South Korea, and characterized taxonomically using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain 15J8-8T belongs to the family Cytophagaceae and is related to Larkinella bovis M2TB15T (95.0%), 'Larkinella harenae' 15J9-9 (94.5%), Larkinella arboricola Z0532T (93.2%), and Larkinella insperata LMG 22510T (93.0%). The DNA G+C content of strain 15J8-8T was 50.5 mol%. The detection of phosphatidylethanolamine and two unidentified polar lipids as major polar lipids; menaquinone-7 as the predominant quinone; and C16:1 ω5c, C16:0 N alcohol, and iso-C15:0 as the major fatty acids also supported the affiliation of the isolate to the genus Larkinella. Based on its phenotypic properties and phylogenetic distinctiveness, strain 15J8-8T should be classified in the genus Larkinella as representative of a novel species, for which the name Larkinella terrae sp. nov. is proposed. The type strain is 15J8-8T (= KCTC 52001T = JCM 31990T).
