Duganella

[3] Morphological characteristics consist of: straight or slightly curved rods, and in liquid growth media, either colonies that are “occasionally fingerlike,” appear, or dispersed growth with little or no formation of colonies appear.

When grown on nutrient agar, the colonies are pale yellow to “straw-colored.”[3] Duganella is able to produce violacein, a vibrant purple compound derived from the condensation of two molecules of tryptophan that is known to be anti-tumor, anti-fungal, and anti-viral.

[6] Duganella is Gram negative, with cellular appendages of a single polar flagellum, making it motile.

Duganella zoogleoides display growth on nutrient or mineral media supplemented with simple organic compounds.

Morphological characteristics include: glistening colonies, convex-shaped with entire margins, and are also pale yellow.
