A yellow-pigmented, Gram-negative, aerobic bacterial strain comprising rod-shaped cells devoid of flagellar and gliding motility, designated strain A31T, was isolated from a veined rapa whelk (Rapana venosa) collected from the South Sea, Republic of Korea. Results from 16S rRNA gene sequence analysis indicated that the isolate belonged to the family Flavobacteriaceae; the highest level of nucleotide sequence similarity (92.6 %) was observed with Tenacibaculum aestuarii KCTC 12569T. The predominant cellular fatty acids were iso-C15 : 1 G (24.2 %), iso-C15 : 0 (20.1 %) and iso-C17 : 0 3-OH (11.2 %). Flexirubin-type pigments were absent. The major isoprenoid quinone was MK-6. The DNA G+C content was 31.7 mol%. Data from a polyphasic taxonomic study suggested that the isolate represents a novel species in a new genus of the family Flavobacteriaceae, for which the name Maritimimonas rapanae gen. nov., sp. nov. is proposed. The type strain of Maritimimonas rapanae is A31T (=KCTC 22186T =JCM 15075T).
A Fitch–Margoliash tree based on 16S rRNA gene sequences and an SEM of cells of strain A31T are available as supplementary material with the online version of this paper.
