Abstract:
A Gram-stain-negative, aerobic, non-motile, non-gliding, yellow-pigmented and rod-shaped bacterial strain, designated 1KV19 T , was isolated from a surface sediment sample collected near a bay in the Arctic. Growth of strain 1KV19 T occurred in 1–4 % (w/v) NaCl (optimum, 2 %), at 4–35 °C (optimum, 25–30 °C) and at pH 6.5–8.0 (optimum, pH 7.0–7.5). The phylogenetic trees based on the 16S rRNA gene sequences showed that strain 1KV19 T was associated with the genus Lutibacter and had the highest 16S rRNA gene sequence similarity to Lutibacter oceani 325-5 T with 98.1 % similarity. Similarity values between strain 1KV19 T and the type strains of other Lutibacter species were in the range 95.9–97.6 %. The average nucleotide identity and digital DNA–DNA hybridization values between strain 1KV19 T and related species of the genus Lutibacter were 76.4–79.1 and 19.9–22.3 %, respectively. The major cellular fatty acids of strain 1KV19 T were iso-C 15 : 0 3-OH, iso-C 15 : 0 and iso-C 16 : 1 H. The respiratory quinone was MK-6. The major polar lipids of strain 1KV19 T were phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids. The phenotypic, genotypic and chemotaxonomic differences between strain 1KV19 T and its phylogenetic relatives indicate that strain 1KV19 T should be regarded as representing a novel species in the genus Lutibacter , for which the name Lutibacter citreus sp. nov. is proposed. The type strain is 1KV19 T (=KCTC 62595 T =MCCC 1H00307 T ).
