Duganella is a genus of bacteria in the Oxalobacteraceae family.{{cite journal | vauthors = Hiraishi A, Shin YK, Sugiyama J | title = Proposal to reclassify Zoogloea ramigera IAM 12670 (P. R.

Duganella is named after the American microbiologist, P.R. Dugan, who first isolated the organism from sewage and polluted water.{{cite book | chapter = Genus II, Duganella | title = Bergey's Manual of Systematic Bacteriology | last = Garrity | first = George M. | name-list-style = vanc | date = 2001 | publisher = Springer Science & Business Media | isbn = 978-0-387-24145-6 | edition = 2nd | volume = 2 | chapter-url=https://books.google.com/books?id=9cwgo-9IyTUC&dq=genus+duganella&pg=PA628 }} Duganella is in class Betaproteobacteria and order Burkholderiales. The molecular percent of Duganella's G/C content is 63–64. 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.” 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.{{cite journal | vauthors = Choi SY, Kim S, Lyuck S, Kim SB, Mitchell RJ | title = High-level production of violacein by the newly isolated Duganella violaceinigra str.

Duganella needs need oxygen to survive. Duganellais mesophilic, neutrophilic, and chemoorganotrophic. 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. The colonies appear to be dry and wrinkly, “leather-like.”
