Abstract 

A lipolytic, Gram-stain-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterial strain, designated BPTF-M16T, was isolated from tidal flat sediment on the Yellow Sea in the Republic of Korea. Strain BPTF-M16T grew optimally at 30 C and in the presence of 2.0?3.0% (w/v) NaCl. A phylogenetic tree of 16S rRNA gene sequences showed that strain BPTF-M16T fell within the clade comprising the type strains of Altererythrobacter species. Strain BPTF-M16T exhibited 16S rRNA gene sequence similarity values of 98.0 and 97.1% to the type strains of Altererythrobacter ishigakiensis and Altererythrobacter marinus, respectively, and of less than 97.0% to the type strains of the other recognized species. Strain BPTF-M16T contained Q-10 as the predominant ubiquinone and C18 : 1!7c as the major fatty acid. The major polar lipids detected in strain BPTF-M16T were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid and one unidentified glycolipid. Mean DNA?DNA relatedness values of strain BPTF-M16T with the type strains of A. ishigakiensis and A. marinus were 22 and 13 %, respectively. The average nucleotide identity value between strain BPTF-M16T and the type strain of A. ishigakiensis was 76.80 %. Differential phenotypic properties, together with the phylogenetic and genetic data, revealed that strain BPTF-M16T is separated from recognized Altererythrobacter species. On the basis of the data presented here, strain BPTF-M16T is considered to represent a novel species of the genus Altererythrobacter, for which the name Altererythrobacter insulae sp. nov. is proposed. The type strain is BPTF-M16T (=KCTC 62421T=KACC 19609T=NBRC 113190T).
