Abstract

A Gram-reaction-negative, rod-shaped, non-motile, red-pigmented bacterium, designated strain GSR3061, was isolated from a water sample of the Mangyung estuary enclosed by the Saemangeum Embankment in JEOLlabuk-do of South Korea, and characterized using a polyphasic approach. 16S rRNA gene sequence analysis of strain GSR3061 indicated that the isolate belonged to the phylum and exhibited similarity levels of 94.7 % to NRRL B-51285, 92.4 % to KACC 14257 and 91.9 % to KACC 15371. Growth was observed at 15–40 °C and pH 6.5–9.5. The major cellular fatty acids of the novel strain were summed feature 4 (comprising iso-C I and/or anteiso-C B), iso-C, Cω6 and iso-C H. Flexirubin-type pigments were absent. The DNA G+C content of strain GSR3061 was 44.9 mol% and the major quinone was MK-7. The polar lipid profile consisted mainly of phosphatidylethanolamine; three unidentified lipids, two unknown aminolipids, two unknown phospholipids, an unknown aminophospholipid and an unknown glycolipid were also present. On the basis of the evidence presented, it is concluded that strain GSR3061 represents a novel species of a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain of is GSR3061 ( = KACC 16450 = JCM 17917).
