Echinicola jeungdonensis sp. nov., isolated from a solar saltern

Abstract

A non-motile and yellow-pigmented bacterium, designated strain HMD3054T, was isolated from a solar saltern in Jeungdo, Republic of Korea. The major fatty acids of strain HMD3054T were iso-C15 : 0 (31.4 %), anteiso-C15 : 0 (23.5 %), iso-C17 : 0 3-OH (14.2 %), summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 6.9 %) and summed feature 9 (comprising iso-C17 : 1ω9c and/or 10-methyl C16 : 0; 6.0 %). The major respiratory quinones were MK-6 and MK-7. The DNA G+C content of strain HMD3054T was 46.9 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD3054T formed a lineage within the genus Echinicola. Strain HMD3054T was closely related to Echinicola vietnamensis KMM 6221T (94.3 % 16S rRNA gene sequence similarity) and Echinicola pacifica KMM 6172T (94.0 %). On the basis of the evidence presented in this study, strain HMD3054T represents a novel species of the genus Echinicola, for which the name Echinicola jeungdonensis sp. nov. is proposed. The type strain is HMD3054T ( = KCTC 23122T  = CECT 7682T).
