Zum biologischen Abbau von Dibenzofuran im Hinblick auf dioxinähnliche Verbindungen

A Contribution to the Biological Degradation of Dibenzofurane with Regard to Dioxins A bacteria was isolated by submerse culturing which is growing on dibenzofurane as the sole carbon source. The adaptation was performed on an activated carbon fixedbed reactor in connection with dibenzofurane and dioxins containing drain water of a disposal for waste chemicals. As a first step of metabolism diphenylether was recognised. This indicates why the furanes within the dioxin-family in the environment are not found in the same concentration as the dioxins although both are emitted most in nearly the same ratio. An other particular feature of the bacteria is the forming of saturated hydrocarbons. The number of carbonatoms goes from 20 to 32, as well even as uneven and as well by aerobic as unaerobic culturing.
