A novel Gram-strain-positive, non-spore-forming bacterial strain, designated GP-S2-8T, was isolated from a sea-tidal flat sediment sample from Gopado, Republic of Korea. Cells were aerobic, catalase-negative, oxidase-positive, non-motile and cocci, occurring singly, in pairs or in tetrads, and often tending to form aggregates. The strain grew at 4-45 °C (optimum, 28-37 °C), at pH 4.0-11.0 (pH 7.0-9.0) and in the presence of 0-11 % (w/v) NaCl (0-3 %). Phylogenetic analyses based on 16S rRNA gene sequences represented that the isolate belongs to the genus Blastococcus. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. Whole-cell sugar analysis of strain GP-S2-8T revealed rhamnose, glucose and mannose as characteristic sugars. The predominant respiratory quinone was MK-9(H4) and the major fatty acids were iso-C16 : 0, iso-C16 : 1 H, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0 and iso-C14 : 0. The polar lipid profile included diphosphadidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol, one unidentified glycophospholipid, two unidentified phospholipids and five unidentified lipids. The DNA G+C content was 74.2 mol%. DNA-DNA relatedness values between strain GP-S2-8T and type strains of the genus Blastococcus ranged from 14.6 to 48.6 %. On the basis of the phenotypic differences and DNA-DNA relatedness data, the isolate represents a new species of the genus Blastococcus, for which the name Blastococcuslitoris sp. nov. is proposed. The type strain is GP-S2-8T (=KCCM 43275T=JCM 32354T=DSM 106127T=KCTC 49078T).
