Abstract

Strain 15J11-11T was isolated from soil collected at the seashore and was Gram-staining-negative, short-rod-shaped, gliding and pale-pink pigmented. Flexirubin-type pigments were absent. The isolate grew at a temperature range of 15 to 30 °C and a pH range of 7 to 8. Comparative 16S rRNA gene sequence studies showed that strain 15J11-11T belonged to the genus Larkinella within the phylum Bacteroidetes and was most closely related to Larkinella arboricola Z0532T (95.6 %), Larkinella bovis M2TB15T (95.4 %), and Larkinella insperata LMG 22510T (95.2 %). The genomic DNA G+C content of strain 15J11-11T was 53.2 mol%. The strain contained phosphatidylethanolamine, phosphatidylserine, an unidentified aminophospholipid and two unidentified polar lipids as the major polar lipids; menaquinone-7 as the predominant quinone and C16:1ω5c, iso-C15:0 and iso- C17:0 3-OH as the major fatty acids which supported the affiliation of strain 15J11-11T to the genus Larkinella. Based on its phenotypic properties and phylogenetic distinctiveness, strain 15J11-11T represents a novel species of the genus Larkinella, for which the name Larkinella ripae sp. nov. is proposed. The type strain is 15J11-11T (=KCTC 42996T=JCM 31657T).
