Abstract

A Gram-negative bacterium, designated strain EMB34, was isolated from a wastewater treatment plant in Korea. Growth was observed between 10 and 40 °C (optimum, 25–35 °C) and between pH 6.0 and 9.5 (optimum, pH 7.5–8.0). The cells were non-motile rods, linked with extracellular fibrils. The predominant fatty acids of strain EMB34 were iso-C, C, iso-C G, iso-C 3-OH and iso-C 3-OH and the strain contained phosphatidylethanolamine and phosphatidylinositol as the polar lipids. The G+C content of the genomic DNA was 34.2 mol% and the major quinone was menaquinone-6. Comparative 16S rRNA gene sequence analyses showed that strain EMB34 formed a distinct phyletic line within the genus . The levels of 16S rRNA gene sequence similarity with other species were less than 94.5 %. On the basis of phenotypic, chemotaxonomic and molecular data, it is clear that strain EMB34 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is EMB34 (=KCTC 12610=DSM 17961).
