Abstract

A long, Gram-negative, rod-shaped bacterium, designated strain EMB13, was isolated from a wastewater treatment plant in Korea. The isolate was strictly aerobic and non-motile. The strain grew optimally at 30–35 °C and pH 7.5–8.0, and the predominant fatty acids were iso-C, summed feature 3 (C 7 and/or iso-C 2-OH), C 5 and iso-C 3-OH. The strain contained a large amount of phosphatidylethanolamine and small amounts of phosphatidylcholine and an unknown phospholipid as the polar lipids. The G+C content of the genomic DNA was 40.1 mol% and the major isoprenoid quinone was menaquinone-7. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain EMB13 belonged to the genus and was most closely related to EMB111, with a 16S rRNA gene sequence similarity of 97.1 %. DNA–DNA relatedness between strain EMB13 and EMB111 was approximately 25 %. On the basis of phenotypic, chemotaxonomic and molecular data, it is clear that strain EMB13 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is EMB13 (=KCTC 12614 =DSM 17976).
