Abstract

A bacterium, designated strain DC-196, isolated from kitchen refuse compost was analysed by using a polyphasic approach. Strain DC-196 was characterized as a Gram-negative short rod that was catalase- and oxidase-positive, and able to grow at 10–40 °C, pH 6–9 and in NaCl concentrations as high as 3 %. Chemotaxonomically, C was observed to be the predominant cellular fatty acid and ubiquinone 10 (Q10) was the predominant respiratory quinone. The G+C content of the genomic DNA was determined to be 66 mol%. On the basis of the genotypic, phenotypic and chemotaxonomic characteristics, strain DC-196 was assigned to the genus , although with distinctive features. At the time of writing, 16S rRNA gene sequence similarities of 97.6–96.8 % and the low DNA–DNA hybridization values of 38.2–32.2 % with the type strains of the three recognized species confirmed that strain DC-196 represents a novel species of the genus, for which the name sp. nov. is proposed (type strain DC-196=CCUG 55808=LMG 24714).
