Complete Genome Sequence of Azoarcus sp. Strain DD4, a Gram-Negative Propanotroph That Degrades 1,4-Dioxane and 1,1-Dichloroethylene.

Azoarcus sp. strain DD4 can cometabolically degrade 1,4-dioxane and 1,1-dichloroethylene (1,1-DCE) when grown with propane and other substrates. The complete genome sequence of strain DD4 reveals a diverse collection of bacterial monooxygenase genes that may contribute to its versatility in degrading commingled groundwater pollutants.
