- Abstract
A Gram-positive, non-motile, aerobic, coccus-shaped bacterium, designated strain LNB-140, was isolated from a sewage treatment plant in the Republic of Korea and was characterised using a polyphasic taxonomic approach. Comparative 16S rRNA gene sequence analysis showed that strain LNB-140 belongs to genus Tessaracoccus in the family Propionibacteriaceae of the phylum Actinobacteria. The 16S rRNA gene sequence similarities between strain LNB-140 and type strains of the genus, Tessaracoccus flavescens SST-39 and Tessaracoccus rhinocerotis YIM101269 are 97.8 and 97.4 %, respectively. The chemotaxonomic properties of strain LNB-140 are consistent with those of members of the genus Tessaracoccus: a quinone system with MK-9(H4) as the predominant menaquinone; anteiso-C and iso C as the predominant cellular fatty acids; and ll-2,6-diaminopimelic acid as the diagnostic peptidoglycan diamino acid. The major polar lipids were identified as diphosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genomic DNA was determined to be 67.1 mol%. Differential phenotypic properties along with low DNA-DNA relatedness (<30 ± 3.2 %) with closely related type strains show that strain LNB-140 is distinct from previously described members of the genus Tessaracoccus and represents a novel species in this genus, for which the name Tessaracoccus defluvii sp. nov. is proposed. The type strain is LNB-140 (=KEMB 5401-076 = JCM 17540).
