Aerobic cometabolic biodegradation of 1,4-dioxane and its …
2023年4月1日 · Aerobic cometabolic degradation of 1,4-dioxane (14D) offers several advantages over metabolism-based biodegradation processes in which microorganisms use this compound as a sole source of carbon and energy for growth.
Cometabolic Treatment of 1,4-Dioxane in Biologically Active …
This research demonstrates that groundwater contaminated by a relatively dil. but persistent concn. of 1,4-dioxane (1,4-D), approx. 60μg/L, and chlorinated aliph. co-contaminants (1.4 to 10μg/L) can be efficiently and reliably treated by in situ aerobic cometabolic biodegrdn.
for 1,4-dioxane. 1,4-Dioxane is biodegradable under aerobic conditions either by direct metabolism or co-metabolism, but the respective roles of these processes depend on both the concentration of 1,4-dioxane and the presence of common chlorinated co-contaminants, such as 1,1,1-trichloroethane (1,1,1-TCA) and 1,1-dichloroethene (1,1-DCE)
Aerobic biodegradation kinetics for 1,4-dioxane under …
2018年5月15日 · Cometabolism of 1,4-dioxane can be achieved with several primary substrates, including propane, methane, toluene, and THF. Metabolism of a primary substrate induces formation of monooxygenases that initiate the oxidation of 1,4-dioxane [9].
Treatment of 1,4-dioxane via enhanced biodegradation processes provides a viable remedial strategy. Both metabolic (i.e., energy producing) and cometabolic (i.e., fortuitous)
