sp. nov., a nitrate-reducing bacterium isolated from activated sludge of an industrial wastewater treatment plant Free

Abstract

A Gram-reaction-positive, rod-shaped, non-spore-forming bacterium (strain 2C1-5) was isolated from activated sludge of an industrial wastewater treatment plant in Daegu, South Korea. Its taxonomic position was investigated by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarity, the closest phylogenetic relatives were the type strains of (98.6 % similarity), (98.5 %), (98.4 %), (98.3 %), (98.1 %) and (97.5 %); the phylogenetic distance from other species with validly published names within the genus was greater than 3 %. Strain 2C1-5 was characterized chemotaxonomically as having -2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-8(H) as the predominant menaquinone and iso-C, C and Cω6 as the major fatty acids. The G+C content of the genomic DNA was 74.9 mol%. These chemotaxonomic properties and phenotypic characteristics supported the affiliation of strain 2C1-5 to the genus . The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 2C1-5 from existing species with validly published names. Therefore, strain 2C1-5 represents a novel species of the genus , for which the name sp. nov. is proposed, with the type strain 2C1-5 ( = JCM 17460 = KCTC 19799).
