A novel Gram-stain-negative, motile by gliding and straight rod-shaped bacterial strain, designated HMF3635 T , was isolated from seawater of the East Sea, Republic of Korea. Strain HMF3635 T grew optimally on marine agar at 30 °C, pH 7.0-8.0 and 2.0 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HMF3635 T belonged to the genus Maribacter and was most closely related to Maribacter arenosus CAU 1321 T (96.4 % sequence similarity) and Maribacter polysiphoniae KMM 6151 T (96.0 %). The major fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The only respiratory quinone was menaquinone 6. The major polar lipids were phosphatidylethanolamine, four unidentified aminolipids, one unidentified phospholipid and three unidentified polar lipids. The DNA G+C content was 38.7 mol%. On the basis of the evidence presented in this study, strain HMF3635 T represents a novel species of the genus Maribacter, for which the name Maribacter maritimus sp. nov. is proposed. The type strain of the species is strain HMF3635 T (=KCTC 52399 T =NBRC 112671 T ).
