NCBI Taxonomy ID:[1]

Description and Significance

Samples of this organism have been extracted from petroleum contaminated soil characterized in acidic sandy loam Cambisol soil in a protected habitat in Rio de Janeiro state, Brazil as well as the perianal swab from a patient with a bone marrow transplant (Yassin, 2006; von der Weid, 2006). Multiple strains of Dietzia have been found in soil, deep sea sediment, and soda lakes (Gerday & Glansdorff, 2007).Dietzia cinnamea is rod shaped in the medical swab while the P4 strain from the soil samples produces a coccoid shape. The organism forms smooth, yellow to orange colonies on agar plates and is single or arranges in small connected colonies. It is gram positive and has a high G+C content, meaning a high number of Guanine and Cytosine linkages in its DNA(Von der Weid, 2006). It displays snapping division, which is the arrangement of cells in a palisade or angular manor resulting from binary fission (Prescott, 2002). This is a characteristic of the genera Arthrobacter and Corynebacterium.
