A Gram negative, yellow-coloured, non-motile, chemoheterotrophic, strictly aerobic, rod-shaped bacterium, designated IMCC1616T, was isolated from the marine polychaete Periserrula leucophryna inhabiting tidal flat sediment of the Yellow Sea, and characterized by a polyphasic approach. The temperature, pH and NaCl ranges for growth were 3-37 °C, pH 5.0-11.0 and 0.5 7.5 %, respectively. – Based on 16S rRNA genesequence similarity analyses, the strain was most closely related to the genera Lutibacter (90.7 %), followed by Tenacibaculum (89.2-90.4 %) and Polaribacter (88.4-90.2 %). The DNA G+C content of the strain was 40.1 mol% and the
predominant cellular fatty acids were iso-C15:0 (16.5 %), anteiso-C15:0 (10.9 %), iso-C17:0
3-OH (8.8 %) and iso-C17:1 ω9c (8.2 %). The DNA G+C content, high amount of iso-C17:1 ω9c and several phenotypic characteristics, including growth temperature and catalase activity, differentiated the strain from other related genera within the family. Therefore, it is proposed from the taxonomic evidences collected in this study, that strain IMCC1616T (=KCCM 42379T =NBRC 102041T) represent a new genus and species named Lutimonas vermicola gen. nov., sp. nov.
