Abstract

A Gram-negative bacterium, designated strain EMB34^T, 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^T were iso-C_15:0, C_15:0, iso-C_19:1 G, iso-C_16:O 3-OH and iso-C_15:O 3-OH and the strain contained phosphatidyl-ethanolamine 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^T formed a distinct phyletic line within the genus Flavobacterium. The levels of 16S rRNA gene sequence similarity with other Flavobacterium species were less than 94.5 %. On the basis of phenotypic, chemotaxonomic and molecular data, it is clear that strain EMB34^T represents a novel species within the genus Flavobacterium, for which the name Flavobacterium Mum sp. nov. is proposed. The type strain is EMB34^T (=KCTC 12610^T=DSM 17961^T.
