Abstract (EN):
A bacterium, designated strain DC-196(T), isolated from kitchen refuse compost was analysed by using a polyphasic approach. Strain DC-196(T) was characterized as a Gram-negative short rod that was catalase- and oxidase-positive, and able to grow at 10-40 degrees C, 16-9 and in NaCl concentrations as high as 3%. Chemotaxonomically, C(18:1) 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(T) was assigned to the genus Shinella, 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 Shinella species confirmed that strain DC-196(T) represents a novel species of the genus, for which the name Shinella fusca sp. nov. is proposed (type strain DC-196(T)=CCUG 55808(T)=LMG 24714(T)).
