Ethene as an auxiliary substrate for the cooxidation of cis-1, 2-dichloroethene and vinyl chloride.

Cultures able to dechlorinate cis-1,2-dichloroethene (cDCE) were selected with ethene (3-20%, v/v) as the sole source of carbon and energy. One mixed culture (K20) could degrade cDCE (400 &mgr;mol l(-1)) or vinyl chloride (100 &mgr;mol l(-1)) in the presence of ethene ( View Article and Find Full Text PDF

A dynamic river model for biodegradability studies: investigations with selected aromatic compounds at low concentrations and comparison with aquatic batch tests.

The objective of this publication is to present a new dynamic aerobic biodegradation test method simulating a river. A laboratory cascade test system and standardized batch shake flask tests were used for biodegradation studies with the non-volatile and non-sorbing model compounds 2,4-dinitrophenol, naphthalene-1-sulphonic acid and sulphanilic acid. To be closer to the often very low concentrations of substances in the environment the concentrations of the compounds used were standard test concentrations and lower.
