Abstract
Methods of removing dioxane and optionally one or more CAHs such as 1,1-DCE, cis-1,2-DCE, trans-1,2-DCE, 1,2-DCA, 1,1-DCA, VC, and TCE from a liquid medium contaminated therewith include applying a feedstream of propane to the liquid medium in the presence of at least one propanotrophic bacteria strain selected from Azoarcus sp. DD4 (DD4) and Mycobacterium sp. DT1 (DT1). Propane, 1-propanol and/or 1-butanol may be employed as substrates in the bioaugmentation of the propanotrophic bacteria strain.
