- Abstract
- A novel Gram-strain-positive, non-spore-forming bacterial strain, designated GP-T3-3(T), was isolated from sediment sampled at a tidal flat in Gopado, Republic of Korea. Cells were aerobic, catalase-negative, oxidase-positive, non-motile cocci that occurred singly, in pairs or in clusters. Strain GP-T3-3(T) grew at 4-45 degrees C (optimum, 28-37 degrees C), at pH 4.0-12.0 (pH 8.0-9.0) and in the presence of 0-15 % (w/v) NaCl (3-5 %). Colonies of strain GP-T3-3(T) were deep-yellow, circular, smooth and pulvinate. The results of the phylogenetic analyses based on 16S rRNA gene sequences indicated that strain GP-T3-3(T) was closely related to Serinicoccus profundi MCCC 1A05965(T) (99.1 %), Serinicoccus chungangensis CAU 9536(T) (99.0 %) and Serinicoccus marinus JC1078(T) (98.0 %). The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The predominant respiratory quinone was MK-8(H-4) and the major fatty acids were anteiso-C-17:0, iso-C-16:0, iso-C(15:0 )and anteiso C-15:0. The polar lipid profile consisted of diphosphadidylglycerol, phosphadidylglycerol, phosphatidylcholine, phosphatidylinositol and two unidentified phospholipids. The DNA G+C content was 72.9 mol%. DNA-DNA relatedness values between strain GP-T3-3(T) and type strains of the genus Serinicoccus ranged from 28.9 to 50.5 %. On the basis of the phenotypic differences and DNA-DNA relatedness data, the isolate represents a new species of the genus Serinicoccus, for which the name Serinicoccus sediminis sp. nov. is proposed. The type strain is GP-T3-3(T) (=KCTC 49173 (T) =JCM 32825(T) =KCCM 43309(T) =KACC 19850(T)).
