Abstract

Trichloroethylene (TCE) was degraded aerobically with the strain Burkholderia cepacia G4. The degradation leveled out after similar to 40 hours, while the removal efficiency depended on the optical cell density (OD540) During the experiment at an OD540 of 0.8, TCE was degraded up to 59.3%, with an isotopic difference between initial and remaining substrate of 12.3 parts per thousand. At a lower OD540 of 0.5 the amount of TCE degraded was only 40.5% and the delta(13)C(TCE) difference between initial and remaining substrate was 10.5 parts per thousand
