Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Perchloroethylene (PCE) contamination is a problem being paid attention to at home and abroad. Co-biodegradation of microorganism is one of effective methods to remove PCE. Yeast powder is a necessary supply and nitrogen nutrient for microorganism growth. In the paper, experiment was carried out to study the effect of yeast powder on PCE biodegradation. The results show that PCE could be biodegraded to Tetrachloroethylene(TCE) and its biodegradation is in accordance with First-order kinetics equation with yeast powder, methanol, yeast powder plus methanol as matrix. The reaction rate constant is relatively high, 0.2629d-1 and half life is 2.637d with yeast powder plus methanol as matrix. Yeast powder provides both nitrogen vital to microorganism growth and co biodegradation matrix, which accelerate PCE biodegradation rate for other co-biodegradation matrix.
