RT Journal Article SR Electronic(1) A1 Lee, Dong Wan A1 Lee, Soon DongYR 2008 T1 Tessaracoccus flavescens sp. nov., isolated from marine sediment JF International Journal of Systematic and Evolutionary Microbiology, VO 58 IS 4 SP 785 OP 789 DO https://doi.org/10.1099/ijs.0.64868-0 PB Microbiology Society, SN 1466-5034, AB A novel actinobacterium, designated strain SST-39T, was isolated from a marine sediment sample collected in Jeju, Republic of Korea. Cells were facultatively anaerobic, Gram-positive, non-endospore-forming, non-motile rods. Colonies were circular, slightly convex, opaque and brilliant yellow. The cell-wall peptidoglycan of the organism contained ll-diaminopimelic acid as the diagnostic diamino acid. Polar lipids included phosphatidylglycerol and diphosphatidylglycerol. The predominant menaquinone was MK-9(H4). The major cellular fatty acids were anteiso-C15 : 0, C18 : 0 and C16 : 0. The DNA G+C content was 68.4 mol%. A phylogenetic tree based on 16S rRNA gene sequences indicated that the isolate belonged to the family Propionibacteriaceae and formed a unique cluster with the type strain of Tessaracoccus bendigoensis (97.0 % sequence similarity). Other phylogenetic neighbours were the type strains of Luteococcus peritonei (95.1 % 16S rRNA gene sequence similarity) and Propionibacterium propionicum (95.1 %). On the basis of its phenotypic and phylogenetic distinctiveness, strain SST-39T is considered to represent a novel species of the genus Tessaracoccus, for which the name Tessaracoccus flavescens sp. nov. is proposed. The type strain is SST-39T (=DSM 18582T =KCTC 19196T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64868-0
