An orange-pigmented bacterium, designated strain 13-9-B8T, was isolated from a seawater sample collected at Marado, Jeju Island, South Korea. The novel strain was Gram-stainingnegative, non-motile, non-gliding, rod-shaped and aerobic. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain clustered with members of the genus Lewinella of the family Saprospiraceae in the phylum Bacteroidetes and was most closely related to the species Lewinella marina (95.6% similarity to the type strain). Strain 13-9-B8T grew optimally at 30 °C, pH 7.0 and with 2% (w/v) NaCl. Strain 13-9-B8T contained MK-7 as the predominant menquinone and summed feature 3, iso-C15: 0 and iso-C17: 0 3-OH as the major fatty acids. The polar lipids detected in strain 13-9-B8T were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and eight unidentified lipids. The DNA G+C content of strain 13-9-B8T was 59.1 mol%. Based on phenotypic, chemotaxonomic and phylogenetic data presented, strain 13-9-B8T is considered to represent a novel species of the genus Lewinella, for which the name Lewinella xylanilytica sp. nov. is proposed. The type strain is 13-9-B8T (=DSM 29526T=KCTC 32663T).
