Abstract

A pink-pigmented, facultatively methylotrophic bacterium, designated strain JT1, was isolated from a thallus of the liverwort L. and was analysed by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis placed the strain in a clade with AR27, DSM 5686, JCM 2831 and S2R03-9, with which it showed sequence similarities of 97.8, 97.7, 97.2 and 97.4 %, respectively. However, levels of DNA–DNA relatedness between strain JT1 and these and the type strains of other closely related species were lower than 70 %. Cells of JT1 stained Gram-negative and were motile, rod-shaped and characterized by numerous fimbriae-like appendages on the outer surface of their wall (density up to 200 µm). Major fatty acids were Cω7 and C. Based on the morphological, physiological and biochemical data presented, strain JT1 is considered to represent a novel species of the genus, for which the name sp. nov. is proposed. The type strain is JT1 ( = DSM 21328  = CCUG 56108).
