A Gram-stain-negative, non-motile, non-spore-forming, ovoid rod-shaped bacterium, designated strain CAU11-72(T), w t iSOlated from lagoon 'sediments along th-e east coast of the Republic of Korea. Strain CAU1172(T) formed a yellow pigment on marine agar. Growth occurred at 20-37 degrees C (optimum, 30 degrees C), at pH 6.5-10 (optimum, 7.5) and in the presence of 0-4% (w/v) NaCI (optimum, 1%). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU1172(T) formed a separate lineage within the genus Altererythrobacter, and was most closely related to Altererythrobacter gangjinensisKJ7(T) (96.1% similarity). Ubiquinone 10 (Q-10) was the predominant respiratory quinone. The dominant fatty acids were C-18:1 omega 7c, C-17:1 omega 6c and summed feature 3 (comprising C-16:1 omega 7c and/or C-16:1 omega 6c). The polar lipids were composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, phospatidylcholine and four unidentified lipids. The DNA G+C content of strain CAU1172(T) 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 CAU1172(T) (KCTC 42453(T)=NBRC 110917(T)).
