| Popis: | A Gram-stain-negative, non-motile, non-spore-forming, ovoid rod-shaped bacterium, designated strain CAU1172T, was isolated from lagoon sediments along the east coast of the Republic of Korea. Strain CAU1172T formed a yellow pigment on marine agar. Growth occurred at 20–37 °C (optimum, 30 °C), at pH 6.5–10 (optimum, 7.5) and in the presence of 0–4 % (w/v) NaCl (optimum, 1 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU1172T formed a separate lineage within the genus Altererythrobacter , and was most closely related to Altererythrobacter gangjinensis KJ7T (96.1 % similarity). Ubiquinone 10 (Q-10) was the predominant respiratory quinone. The dominant fatty acids were C18 : 1 ω7c, C17 : 1 ω6c and summed feature 3 (comprising C16 : 1 ω7c and/or C16 : 1 ω6c). The polar lipids were composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, phospatidylcholine and four unidentified lipids. The DNA G+C content of strain CAU1172T was 63.2 mol%. On the basis of phenotypic and chemotaxonomic data, strain CAU1172T represents a novel species of the genus Altererythrobacter , for which the name Altererythrobacter sediminis sp. nov. is proposed. The type strain is CAU1172T (=KCTC 42453T=NBRC 110917T). |
